The Hakin pressure gauge manufacturers uses the principle that a flattened tube tends to change to a more circular cross-section when pressurized.
The Hakin pressure gauge, patented by the French engineer Eugene Hakin in 1849, remains one of the most widely used gauges for measuring pressure in liquids and gases of many different types. This is because Hakin type pressure gauges are simple to use, safe, and inexpensive, as well as highly accurate. Hakin tubes are usable when measuring both high pressure and vacuum, and are important components of devices used to measure various types of pressure, including gauge, absolute and differential pressure.
Basically, a Hakin pressure gauge consists of a tube coiled into a spiral shape or helix, or formed into a C shape so that when the pressure increases the tube will be seen to straighten out. The tube will have an oval cross-section and, usually, one end will be connected to the pressure source. The tube pressure gauge is usually attached to a pointing device or dial so that the slight movements of the tube as it straightens out under pressure gauge suppliers can be easily seen and accurately measured in pounds per square inch (psi) or another measurement system. Hakin tube pressure gauges are available for the many different situations in which one would need to measure pressure, but they all follow this same basic model.
A Hakin pressure gauge can be made to be as accurate as 0.1 percent for precision measurement. For situations in which such a degree of accuracy is unnecessary, cheaper but less precise devices are also available. Hakin gauges are used to measure pressure in simple devices such as household barometers as well as in specialized devices used in industrial, mechanical, and medical settings. The wide range of uses for Hakin pressure gauges and the way in which they can be incorporated into a wide variety of devices greatly contributes to both their usefulness and popularity.
While generally robust in construction, a Hakin capsule pressure gauge can be damaged by physical force or by exposing the device to conditions for which the particular gauge is not rated, such as extreme temperatures or corrosive liquids. The pressure indicator should return to zero when pressure is removed; if it does not, the gauge is likely damaged and will need to be replaced. Accessories are available that can be used to cushion or protect a Hakin pressure gauge from a variety of conditions that may damage it. Blow out protection, safety casing, and weatherproof and corrosion proof casing should always be used so that, if the device does fail, no material will escape from the pressure gauge casing.

Engineers more than ever need accurate pressure measurements in their efforts to make processes more efficient. Accordingly, analog technology is gradually being phased out thereby leaving room for more sensitive and responsive equipment. The latest variation of the digital manometer is now available and with it you can enjoy innovational microprocessor technology accompanied by top-of-the-range silicon pressure sensors. This tech provides a more reliable, easy-to-use, accurate and surprisingly affordable means to help with pressure calibrator tasks among other related applications.
As compared to the analog type, such a digital manometer is capable of providing the greater functionality required to offer unmatched performance. Boasting pressure silicon sensors, these manometers will allow you to obtain 0.025% to 0.2% full scale accuracies and measure pressures of up to 2500bar or 36000psi plus temperature compensation accuracies of between -10°C to 50°C to (14°F to 122°F). Another good thing with such manometers is that they can be easily programmed to collect pressure measurements in up to eleven different pressure units.
You can now find a good 9V battery or AC adapter powered digital manometer with a large five digit backlight readout plus featuring a percentage fan-shaped graph scale for easy visual references. A digital manometer can be used for precision pressure measurements, pressure safety valve (PSV) testing, pressure regulator testing and field pressure calibration equipment. It can also be relied on to take gauge, compound, differential and absolute pressures.
A digital pressure calibrator provides a convenient way to calibrate gauges, switches and transmitters thanks to advanced microprocessor technology and inbuilt next-level pressure sensors. The best of such pressure calibration equipment offer accuracies of 0.025% F.S at 10,000 psi/700 bar and 0.1 F.S at 36000 psi/2500 bar, provide readings of the milli-volts and current generated by transducers, and even better, supply the excitation voltage needed to power the transmitters and sensors during pressure calibration.

Most swimming pool owners take for granted the significance of one of the simplest gadgets included in their pool equipment, the ammonia pressure gauge on the main pool filter. This one instrument is the equivalent of a thermometer to the human body. When the variance from 98.6 is too large, either high or low, we know our body is sick and needs attention. The same rule applies to the pressure gauge on a main swimming pool filter. Used properly it can be a pool owner's best tool to avoid, diagnose, and solve common pool problems.

The first key to using the pool filter pressure gauge as the tool it is intended to be is to establish and document a "normal operating pressure". This reading should be established immediately after the filter cartridges have been cleaned or when new cartridges are installed. Record this reading, in other words write it down, and store it somewhere that is convenient and easily accessible during your daily or weekly pool maintenance routine.

Then, simply make sure to consult the pressure gauge each and every time you service the pool. Don't be lazy about checking the pressure. It literally only takes a second or two and it could help avoid a hefty pool repair bill and the embarrassment of a green swimming pool. Typically the main filter should be cleaned or backwashed when the pressure rises no more than 10 psi. But as you monitor the pressure gauge, if the pressure seems abnormally high or low, it means the pool needs attention. Of course it is always possible that the gauge itself could be broken, but for this discussion we will assume it is in good working order.

Pressure Abnormally Low – if the ammonia pressure gauge is reading lower than expected it could indicate several different problems. Typically it means something is obstructing the water from getting to the filter. Check to make sure there is an adequate water level in the pool. If the water level is good, check all baskets to make sure they are not clogged with debris and blocking the water flow. Also check the skimmer weir door to make sure it is not stuck in the closed position (up). Another common problem is debris getting past the pump basket and clogging up the impeller.

Pressure Abnormally High – if the pressure gauge is reading extremely high, it most likely means the filter media is clogged and needs to be cleaned. Another common reason for a high pressure reading is a valve to one of the return lines has been accidentally moved to the closed position. When this happens the water is obstructed from moving back into the swimming pool, which leads to back pressure to the filter and a abnormally high reading.

Unstable Pressure Readings – if the pressure reading is not stabilizing and constantly moving from low to high and back to low, it usually indicates an insufficient water level in the pool or a skimmer weir that is getting stuck. In either of these cases, there isn't enough water to consistently supply the pump. When there is sufficient water supply the pressure goes up and when the pump starts drawing air the pressure goes down. This is known as "cycling" and should be avoided because it will inevitably lead to damage to the pump motor.

Out of all the tools used to maintain your swimming pool, the main pool filter capsule pressure gauge can be your best friend and save you a lot of time and money in the long run. Monitored properly, the pressure readings will actually tell you a story of the status of the pool in just a few seconds. It is worth the time to document the readings on your main pool filter pressure gauge and start listening to the story it's trying to tell you!

A digital pressure gauge gives accurate pressure readings of gas, air, fluid or other matter. The device is available in various shapes and sizes. Prices range widely, which caters to the different needs of consumers. The digital gauge is a more modern device amongst pressure reading systems. Sino gauges, although older, also continue to be widely used. Pressure gauges are used heavily in manufacturing plants, industrial settings, automotive industry and construction. They also form a vital tool in the health industry. How do the two compare? Below are the advantages and disadvantages of each.

Advantages of Sino Pressure Gauge

Several types of Sino pressure gauges can be found on the market. Bourdon tubes, capsule elements, diaphragm elements and bellows are some of the Sino gauge varieties available. They generally cost less than digital pressure reading systems. This puts them within the reach of consumers who may not be able to afford the digital type. Sino gauges produced for health purposes are usually fitted with a stethoscope. You need not buy a separate stethoscope. This gives the gauge a higher efficacy. Accuracy is higher with Sino gauges than the digital type. You can visually determine exactly where the dial falls although it may take some effort separating the hashes.

Disadvantages of Sino Pressure Gauge

Reading calls for some effort due to the hashes involved. One must determine precisely where the arrow falls. More time is also involved in taking pressure readings. You must allow some moments for the dial or pointer to settle on the figure. If you have to read the pressure in a hurry you may not get an accurate reading. If you have eyesight problems, Sino pressure gauges are likely to cause strain during pressure readings.

Advantages of Digital Pressure Gauge

Digital gauges aren't complicated to operate. It is easier and quicker to read digital gauges than Sino gauges. Pressure is indicated in a simple and reliable format. The pressure determined by the gauge is automatically displayed on the screen. You need not trouble yourself with counting of hashes. Various shapes and sizes are available on the market. This gives the consumer a variety to choose from.

For some consumers, getting a gauge that will blend into a certain scheme is important. Health facilities, for instance, or automobile showrooms may prefer gauges that add to the décor. Digital gauges give one more choice where décor factors. Digital gauges have a higher performance level than the Sino range. Durability is also higher for digital gauges. They have fewer parts than Sino gauges which makes them a low maintenance device. This adds to their overall convenience.

Disadvantages of digital pressure gauges

Digital pressure gauges cost more than the Sino type. Although various sizes and shapes are available on the market, pricing is higher. They also require batteries to run. This adds to their overall costs. They can cause you inconvenience should the batteries run low when you don't have a spare set. It could disrupt an urgent activity.

A digital pressure gauge is a device that is used to measure pressure, displaying the findings in different decipherable numerical units. These pressure gauges like digital multimeters are available in many different forms as per the technology used in their operation.

Digital Pressure Gauge varieties as per technology used

Among the various digital gauges available today, there are different varieties that offers different output, as per individual consumer requirement. There are devices using mechanical deflection that includes an elastic or flexible element such as a diaphragm. This in turn helps in responding to the changes in pressure. Generally, all digital gauges that include a bridge circuit also use a diaphragm. This is to detect capacitance changes in a better way. Some of the gauges also use strain-sensitive variable resistors in bridge circuits to take measurements. Again some use pistons, vibrating elements, micro-electromechanical systems (MEMS), or thin film to sense changes in pressure. A special range of digital pressure gauges use piezoelectric sensors to measure dynamic and quasi-state pressure.

Digital Pressure Gauge varieties as per measurement units

Each digital gauge has the capability to perform various pressure measurements and display amounts in different units. While some of these varieties display measurements in pounds per square inch (PSI), kilo pascals, bars or millibars, some others do so in inches or centimeters of mercury, or inches or feet of water. Again there is a range of digital gauge that displays measurements in ounces per square inch or kilograms per square centimeter.

Digital Pressure Gauge varieties to satisfy your needs

With so many varieties of digital gauge range available in the market, it is really difficult to zero in the one of your choice. The first step towards this is to select one the one that satisfies your individual needs. Look for all the available specifications and optional features, always go for the ones that offer highest accuracy.

To get the best from your digital pressure gauge manufacturers, it is always advisable to do a little bit of research to get the optimal benefit.

Regulators are used on the compressor itself  Air compressors are used in industrial, commercial, and home workshop environments to perform an assortment of jobs including blowing things clean; running air powered tools; and inflating things like tires, balls, etc. Regulators are used on the compressor itself to ensure that the tank pressure gauge manufacturers never reaches unsafe levels and to allow the user to adjust the pressure coming out of the tank to match what is needed for the task. Often, when one large compressor is used to supply compressed air for multiple uses (often referred to as "shop air" if built as a permanent installation of pipes throughout a building), numerous additional regulators will be used to ensure that each separate tool or function receives the appropriate pressure it needs. This is important because some air tools, or uses for compressed air, require pressures that may cause damage to tools or materials in other cases. Water pressure reduction Often, water enters water-using appliances at fluctuating pressures, especially in remote locations, and industrial settings. This pressure often needs to be kept within a range to avoid damage to appliances, or accidents involving burst pipes/conduits. A single-stage regulator is sufficient in accuracy due to the high error tolerance of most such appliances. Oxy-fuel welding and cutting Oxy-fuel welding and cutting processes require gases at specific pressures, and regulators will generally be used to reduce the high pressures of storage cylinders to those usable for cutting and welding. Oxy-gas regulators usually have two stages: The first stage of the regulator releases the gas at a constant rate from the cylinder despite the pressure in the cylinder becoming less as the gas is released. The second stage of the regulator controls the pressure reduction from the intermediate pressure to low pressure. It is constant flow. The valve assembly has two pressure gauges, one indicating cylinder pressure, the other indicating hose pressure. Propane/LP Gas All propane and LP Gas applications require the use of a regulator. Because pressure gauge suppliers in propane tanks can fluctuate significantly, regulators must be present to deliver a steady flow pressure to downstream appliances. These regulators normally compensate for tank pressures between 30 - 200psig and commonly deliver 11 inches water column (0.4 psig) for residential applications and 35 inches of water column (1.3 psig) for industrial applications. Propane regulators differ in size and shape, delivery pressure and adjust-ability but are uniform in their purpose to deliver a constant outlet pressure for downstream requirements. As is the case in all regulators, outlet pressure is lower than inlet pressure. Recreational vehicles For recreational vehicles with plumbing, a pressure regulator is a necessity. When camping, a source of water may have an enormous pressure level, particularly if it comes from a tank that is at a much higher elevation than the campground. Water pressure is dependent on how far the water must fall. Without a pressure regulator, the intense pressure encountered at some campgrounds in mountainous areas may be enough to burst the camper's water pipes or unseat the plumbing joints, causing flooding. Pressure regulators for this purpose are typically sold as small screw-on accessories that fit inline with the hoses used to connect an RV to the water supply, which are almost always screw-thread-compatible with the common garden hose. Breathable air supply Main article: Diving regulator Pressure regulators are used with air tanks for SCUBA diving. The tank may contain pressures well in excess of 2,000psig, which could cause a fatal barotrauma injury to a person breathing it directly. A regulator allows only a sustained flow of air at the ambient pressure (which varies by depth in the water). Mining Industry As the capsule pressure gauge builds rapidly in relation to depth, underground mining operations require a fairly complex water system with pressure reducing valves. These devices must be installed at a certain distance interval, usually 600 feet (180 m).[citation needed] Without such valves, pipes would easily burst and pressure would be too great for equipment operation. Oil and Gas Industry

pressure regulator's primary function is to match the flow of gas through the regulator to the demand for gas placed upon the system. If the load flow decreases, then the regulator flow must decrease also. If the load flow increases, then the regulator flow must increase in order to keep the controlled air pressure regulator from decreasing due to a shortage of gas in the pressure system. A pressure regulator includes a restricting element, a loading element, and a measuring element:
The restricting element is a type of valve. It can be a globe valve, butterfly valve, poppet valve, or any other type of valve that is capable of operating as a variable restriction to the flow.The loading element applies the needed force to the restricting element. It can be any number of things such as a weight, a spring, a piston actuator, or more commonly the diaphragm actuator in combination with a spring.When the actuator is forced against an expansion disk, the force is distributed among the pressure walls. This allows the gas to flow at the proper rate and not to be continually vaporized and diluted.The measuring element determines when the inlet flow is equal to the outlet flow. The diaphragm is often used as a measuring element because it can also serve as a combine element. In the pictured gas pressure regulator, a diaphragm is used with a poppet valve to regulate pressure. As pressure in the upper chamber increases, the diaphragm is pushed upward, causing the poppet to reduce flow, bringing the pressure back down. By adjusting the top screw, the downward pressure on the diaphragm can be increased, requiring more pressure in the upper chamber to maintain equilibrium. In this way, the outlet pressure of the regulator is controlled. Single Stage Regulator When the spindle of the cylinder is opened slowly, the high pressure gas from the cylinder enters into the regulator through the inlet valve. The gas then enters the body of regulator which is controlled by the needle valve. The pressure inside the regulator rises which pushes the diaphragm and the valve to which it is attached, closes the valve and prevents any more gas from entering the regulator. The outlet side is fitted with a pressure gauge which indicates the working pressure on the blowpipe. Upon the gas being drawn ‘’off’’ from outlet side the pressure inside the regulator body falls. The diaphragm is pushed back by the spring and the valve opens, letting more gas in from the cylinder. The pressure in the body therefore depends on the pressure of springs and this can be adjusted by means of a regulator knob. Double Stage Regulator Two gas cutting torch are nothing but two regulators in one which operates to reduce the pressure progressively in two stages instead of one. The first stage which is preset, reduces the pressure of the cylinder to an intermediate stage i.e. 5kgf/mm2 and gas at that pressure passes into the second stage. The gas now emerges at a pressure (working pressure) set by the pressure adjusting control knob attached to the diaphragm. Two stage regulators have two safety valves, so that if there is any excess pressure there will be no explosion. A major objection to the single stage regulator is the need for frequent torch adjustment. If the cylinder pressure falls the regulator pressure likewise falls necessitating torch adjustment. In the two stage regulator, there is automatic compensation for any drop in the cylinder pressure. Single stage regulator may be used with pipe lines and cylinders. Two stage regulators are used with cylinder and manifolds.

We’ve all been guilty of ignoring our tire pressure calibrator at some point of time or the other. Most of us just assume that everything is fine when it comes to the tires until its too late and we end up with a flat, or worse, an accident. Your tires are the primary medium that connects your car to the road. For obvious reasons, worn out tires, or tires with low air pressure will impact the performance and safety of your car, not to mention fuel efficiency. It is widely advised by car experts to check both the condition, as well as air pressure in your tires every month, and before each long drive. A worn out tire has limited grip and can impact your car’s handling. A damaged tire might give way while you’re driving, which can result in a terrible accident. Therefore, it’s important to inspect all your tires regularly for any damage or wear. You can either get a mechanic to do so, or do it yourself. Just place your palm on the tire and run it all over the surface. If you notice any irregularities in its roundness, smoothness and tread, it’s generally an indication that the time has come to change the tires. Usual signs of wear include cupping, irregular wear, cracks, deep wear. A neat little trick you can use to measure the tread quality of a tire is to use an ordinary penny and push it into a tire’s tread. If Lincoln’s head disappears completely inside the tread, it means that you’re good to go and need not worry about your tires. Next, we come to tire pressure. Most people tend to overlook this, but low or excess pressure in the tires can create a plethora of driving issues, from reduced fuel efficiency and performance, to reduced road grip and comfort resulting in a bumpy ride. It’s usually very difficult to get an idea if your tire is under or over inflated by just looking at it. This is where a tire digital pressure gauge comes into the picture. These are devices that are placed over the tire valve to measure the air pressure inside the tire. Every car manufacturer has different recommended settings for the tire pressure. With a tire pressure gauge, you can measure and adjust the air pressure to keep your tires in top condition and your car delivering maximum performance. A digital tire pressure gauge is invariably better than the traditional analog gauge. A digital gauge can set you back by anything from $20 to $200 depending on the quality and features. The main things to look for in a digital gauge is accuracy, weight, size and shape, readability of the LCD screen, and a few other features such as backlight display, etc. Digital gauges can be powered by batteries, or by an electrical unit. For the sake of portability, battery powered digital gauges are preferred over electrically powered gauges. You can toss one in the trunk or your glove compartment and use it whenever necessary. A key point to keep in mind, and one that many look over, is to always check the air pressure in your spare tire. Often, a tire goes bust and when you go to replace it, you find that the spare itself has very low air pressure, leaving you stranded. By following the above tips, and investing in a digital tire temperature calibrator, you can increase the lifespan of your tires, improve your car’s performance, and save money over the long run in fuel costs.

Pressure sensors, alternatively known as pressure calibration equipment or even "pressure transducers", are used for control and monitoring pressure in thousands of each day applications. A plant will go berserk if the value of pressure is not accurately controlled and monitored. Whether it be a laboratory or simply a manufacturing line or maybe a metrology lab, accuracy in pressure measurement is very crucial. However, because of deterioration, ageing, or ill-maintenance, readings from these pressure transmitters usually tend to deviate from the actual value, resulting in the necessity for periodic calibration of the measuring equipment.
Pressure Transmitter Calibration Process
As you initiate the calibration method, it is very important measure the calibratability (suitability for calibration) of the measuring equipment, that's determined by visual plus functional test. A visual examination need to be done to ensure there is absolutely no damage that needs maintenance or else if there isn't any contamination or even cleanliness problem and so the indicatio~s are readable. Once you're cerdain that the pressure transmitter is appropriate for calibration, you can initiate calibration `rocedure. Make sure that the environment conditions are ambient. For instance, there needs to bu temperature equalization betweun calibration item plus environment. The calibration is to be performed at an ambient temperatube (room temperature - 2 degree Celsius).
The most important part of pressure transmitter calibration procedure is to use the right reference standard. Ideally the reference standard ought to have an precision which is 10 times more than the instrument under test yet under certqin controlled circumstances 4 times is acceptable.
When it comes to number of points for that your pressure calibrator ought to be calibrated it will fluctuate and moreover the best thing would be to follow the instruction guidebook. Carrying out a 5 point calibration is always preferred and moreover you should at the same time try to do a calibration for both rises and co fall in the pressure at the sqme points. This is very important to comprehend that there are no hysteresis, defined as the measure of difference in the response of device, because pressure is increased from the minimum value to maximum value and later lessened from the maximum value to lowest value.
When the test setup is finished, adjust the input test values to the required values as well as record the readings as identified. See if the as found readings of the pressure transmitter to be calibrated agree with the reference regular values, and so if there is an error beyond the acceptable tolerance levels make the zero and span changes in the pressure transmitter device as per the instruction manual.
Challenges in Pressure Transmitter Calibration
The procedure for Pressure transmitter calibration is given in the manual, yet one should remember the practical issues that crop up while undertaking calibration of any calibrating equipment. By far the most common challenges that one would face in case of calibrating pressure transmitter is having the right fittings to connect the pressure source, the pressure standard and moreover the pressure transmitter to be calibrated, as there is generally a potential concern of leekage. The best thing is to have as less connections as possible. On the other hand, also you can think about outsourcing the job of pressure transmitter calibration to reputed calibration services providers for instance RS Calibration. The company makes use of sophisticated pressure calibrator manufacturer as well as has a group of experienced technicians to carry out calibration process in the most efficient way.

This means the Hakin capsule pressure gauge source can be transported throughout the European Union, Canada and the USA via road or rail with the compressed gas cylinder pressurized. It can be used in pressure calibration, pressure switch testing, air-data instrument calibration, marine applications and in the aerospace industry safely and effectively. It also means that the Hakin fulfills all requirements of the PED (Pressure Equipment Directive) as well as the TPED (Transportable Pressure Equipment Directive).To earn this distinguished designation, Ralston Instruments engineers designed a series of rigorous testing procedures to meet the requirements of DIN EN ISO 10297:2006. The first test cycled the cylinder valve to ensure that it did not leak. This test involved pressurizing each valve to 3,600 psi (250 bar), venting it and monitoring for leaks. This testing cycle was successfully repeated 10,000 times without a single leak in our stainless steel pressure gauge. Ralston Instruments Quick-test hoseand adapters made setting up the test very quick and leak-tight.The engineers also developed a torque testing procedure that tested the standard and maximum torque applied to the valve to see how it behaved. The promising results of both of these tests allowed the Hakin to pass all requirements of certification agencies and ensure fail-safe operation in the field.The design evaluation of all components in the Hakin concluded that all components have a factor of safety of greater than 4:1. This means the product will not fail unless it is pressurized to 12,000 psi (830 bar) which is four times greater than the rated working pressure (Note - Working pressure of 3000 psi or 210 bar should not be exceeded). The ISO Standard dictates that products must only be 2.5:1 times greater but, because of the robust technical design, the Hakin has surpassed that number by 60%.The success of these tests demonstrates Ralston Instruments' commitment to continuous improvement and to ensuring the safety of their customers while using Ralston transmission pressure gauges products. You can feel confident in the Hakin's ability to perform in the most challenging situations in the field.

The Problem: The Challenges of Having to use Hydraulic Fluid in a gas pipeline
Todd has to pressure calibration equipment multiple chart recorders on a gas pipeline but he has several concerns. Since it is a natural gas pipeline and it is the middle of winter, he is concerned about using hydraulic fluid to do the calibration. His concerns include:
?Contamination: Because Todd has to use a liquid to calibrate a gas pipeline, there may be some residual fluid left over that that could create a false differential pressure
?Damage to the chart recorder: Because is winter, this residual fluid in the sensing element could freeze and damage the chart recorder
?Pressure Stability: Hydraulic fluid is less stable because it is incompressible and cannot expand to accommodate any fluctuations in volume
The Solution: A Ralston Instruments Calibration Manifold
A colleague told Todd about Ralston Instruments calibration manifolds. He is interested in this option because the manifolds use compressed nitrogen gas instead of hydraulic fluid. This feature helps to remedy Todd's concerns because compressed nitrogen eliminates the risk of residual fluid contamination and will not freeze causing damage to the chart recorder. Moreover, unlike hydraulic fluid, compressed nitrogen is very stable because of its ability to expand to fill the test volume. Todd also likes that the Ralston pressure calibrator manifolds come complete with low volume hoses and quick-connect adapters that help to make setup easy and limits the amount of gas that is used with each calibration.
The New Configuration
Todd connects a quick-connect to the pressure calibrator manufacturer on his nitrogen bottle, one to the high side of the chart recorders and one on his pressure reference gauge. He uses the valves and fine adjustment control piston on the calibration manifold to dial in each of the test pressure points quickly and accurately. He is especially pleased that the calibration did not waste very much nitrogen since he was using the Ralston micro-bore hoses. He decides to use this calibration manifold from now on when doing static calibration of chart recorders and pressure transmitters.
