Diaphragm Pressure Gauge Working Principle

When the pressure P of the measuring medium acts on the diaphragm type pressure gauge, the diaphragm deforms and compresses the sealing liquid of the pressure measuring system of the pressure instrument to form a pressure of P-Delta P. When the rigidity of the diaphragm seal pressure gauge is small enough, Delta P is also very small, and the pressure formed by the pressure measuring system of the pressure meter is close to the pressure of the measuring medium.

What is Diaphragm Seal Type Pressure Gauge?

The diaphragm seal type pressure gauge is composed of a diaphragm isolator and a universal pressure gauge to form a system of diaphragm pressure gauges. The connection between the gauge diaphragm seal and the equipment mainly includes threaded connection, flange connection, and sanitary clamp type. The diaphragm seal type pressure gauge working is suitable for measuring the pressure of the medium with strong corrosion, high temperature, high viscosity, easy to crystallize, easy to solidify, and solid floating matter. It is necessary to prevent the measuring medium from directly entering the general pressure instrument and prevent the accumulation of sediment and easy to clean.

FAQ of Diaphragm Pressure Gauges
Q
What is the difference between gauge diaphragm seal and other pressure gauges?
When the measured medium is very corrosive (such as hydrochloric acid, wet chlorine, ferric chloride), has a high viscosity (such as latex), easy to crystallize (such as salt water), easy to solidify (such as hot asphalt), there is a solid floating matter (such as sewage), SUS316 stainless steel pipe will also be corroded by hydrochloric acid. The floating matter in asphalt and sewage will quickly block the pressure guide hole of the pressure gauge, and make the meter lose its function. Diaphragm type pressure gauge can solve these problems. People can choose different corrosion-resistant diaphragm materials according to different strong corrosive media to play a role in corrosion protection.

Q
What situation dose a diaphragm vacuum pressure gauge work?
The diaphragm pressure gauge is mainly used in petroleum, chemical, chemical fiber, dyeing, pharmacy, soda food and other industrial sectors.

Q

What is Electrical Contact Pressure Gauges?

The pressure gauge with electrical contact is composed of a measuring system, an indicating system, a magnetic-assisted electric contact device, a casing, an adjustment device, and a junction box (plug seat). General electrical contact pressure gauges are used to measure the positive and negative pressures of gas and liquid media that are not corrosive to copper and copper alloys. Electrical contact pressure gauges are widely used in petroleum, chemical, metallurgy, power stations, machinery and other industrial sectors or mechanical and electrical equipment to measure the pressure of various fluid media without explosion hazard. Generally, the contact pressure gauge is used in conjunction with the corresponding electrical devices (such as relays and inverters, etc.) to automatically control and send signals (alarms) through the meter for various gas and liquid media whose pressure is measured (controlled).

Advantages of CG Electric Contact Pressure Gauges

The electrical contact signal pin of the electrical contact pressure gauge device is equipped with an adjustable permanent magnet, which can increase the suction force of the contact and accelerate the contact action, so that the contact is reliable, the arc can be eliminated, and it can effectively avoid the frequent shutdown of the contacts of the instrument due to the vibration of the working environment or the pressure pulsation of the medium. Therefore, the electric contact pressure gauge has the advantages of reliable action, long service life, and large contact switch power. The instrument also has the advantages of combined measurement and control, simple installation, and small maintenance.

How to Test Electric Contact Pressure Gauges

1. The electric contact pressure gauge is actually a circuit switch operated by the pressure gauge.
It is only an electric contact signal device added to the ordinary pressure gauge. Therefore, the verification of the pressure part is the same as that of the ordinary pressure gauge, except that the pressure part is qualified. Only after the pressure part has passed the verification, the verification of the electric contact signal device needs to be added.

2. Verification steps of electric contact pressure gauge

Install the pressure gauge on the calibrator, use the needle selector to set the two signal contact pointers outside the upper and lower limits respectively, and then perform the value verification. After the indicating value verification is qualified, set the upper and lower signal contact pointers at three or more different verification points respectively, slowly increase or decrease the pressure until the signal is sent. Then the deviation between the reading of the standard pressure gauge and the indicated value of the signal pointer shall not exceed the absolute value of the allowable basic error.

Electric Contact Pressure Gauges working principle

The electric contact pressure gauge is based on the spring tube in the measuring system under the pressure of the measured medium, forcing the end of the spring tube to produce corresponding elastic deformation and displacement. It is driven by the gear transmission mechanism with the help of the pull rod and amplified. The indication (together with the contact) will indicate the measured value on the dial one by one. At the same time, when it is in touch with the contact (upper or lower limit) on the setting pointer (moving off or on), the circuit in the control system can be disconnected or connected to achieve automatic control and transmission, in order to achieve the purpose of automatic control and sending an alarm.

Functions of Differential Pressure Gauges

DP pressure gauge is widely used in industry to measure the pressure of fans and blowers, filter resistance, wind speed, furnace ventilation, pressure drop caused by orifices, the liquid level of the bubbling system and the pressure of the booster or hydraulic system. Differential pressure instruments can also detect gas-air ratio and automatic control valves, as well as monitor blood and respiratory pressures on medical equipment. DP pressure gauges are also applied in other areas like medical and health, microelectronics, aerospace, environmental protection engineering, bioengineering, pharmaceuticals, building intelligence, HVAC, food and beverage, precision electronic processing, aquaculture, etc.

Advantages of CG Differential Pressure Instruments

CG differential pressure instruments have a reasonable structure design of novel appearance. Using advanced technology, they are designed in small size, light weight, good stability with long service life and strong adaptability. The connection form of the instrument joint has two kinds of parallel type (which can be directly connected with the second valve group) and oblique type, which can adapt to the matching installation of different users. The CG Differential Pressure Gauges adopt a double bellows structure, that is, two bellows are respectively installed on the symmetrical positions on both sides of the "I"-shaped bracket. CG differential pressure instruments have many innovative uses, for example, they are a less expensive and simpler choice for you to monitor the heavy and expensive flow of fluids inside a pipe.

DP Gauge Working Principle

DP gauge is used to measure the difference between two pressures. The medium cavity of the DP gauge is separated into two parts by the pressure element. If the two measured pressures are equal, the pressure element will not move and the output of the pressure gauge is zero. If the two pressures are not equal and there is a pressure difference, the differential pressure gauge will indicate the pressure difference. It transmits the displacement of the pressure element through mechanical movement and indicates the pressure difference. Using simple, frictionless stimulating movement, differential air pressure gauge can quickly measure non-destructive positive pressure, negative pressure or differential pressure of air.

Meaning of Fire Extinguisher Pressure Gauge Pointer in Different Areas(2022年06月21日)

gaugechina — 2022-06-15T15:05:15+0900

https://www.gaugechina.com/meaning-of-fire-extinguisher-pressure-gauge-pointer-in-different-areas.html

The dial of the fire extinguisher pressure gauge indicator is divided into three color areas. The pointers of the pressure gauge in different color areas have different meanings. The first area is red, the second area is green, and the third area is yellow. Below we explain the meaning of the fire extinguisher electric contact pressure gauges pointer in different areas.

1. The pointer of the fire extinguisher pressure gauge is in the red area

If the internal pressure of the fire extinguisher is less than 1.0 MPa (refill), it means that the pressure inside is not enough to effectively spray the fire extinguishing agent. At this time, we need to take the fire extinguisher to the fire equipment store or the local fire brigade to refill it.

2. The pointer of the fire extinguisher pressure gauge is in the green area

If the pointer of the fire extinguisher gauge pressure gauge is in the green area, it shows that the pressure of the fire extinguisher is normal, and the fire extinguisher can be used normally.

3. The pointer of the fire extinguisher pressure gauge is in the yellow area

It shows that the pressure inside the fire extinguisher is too high and exceeds the standard value. If we use a fire extinguisher at this time, although the foam can be sprayed normally, there is a danger of explosion. It is recommended to take it to the fire shop to replace it as soon as possible.

The fire extinguisher should undergo a visual inspection every month, mainly checking the pressure gauge of the fire extinguisher. When the pointer of the pressure gauge is lower than the green line area, it should be charged and repaired immediately; the tank body of the newly purchased ABC dry powder fire extinguisher should be hydrostatically tested every 5 years. After the first inspection, the hydraulic pressure test will be carried out every 2 years thereafter, and the mandatory period for the tank body to be scrapped is 10 years.

Maintenance of Pressure Gauge(2022年06月19日)

gaugechina — 2022-06-15T15:03:52+0900

https://www.gaugechina.com/maintenance-of-pressure-gauge.html

To keep pressure gauges sensitive and accurate, in addition to reasonable selection and correct installation, the maintenance and inspection of pressure gauges should be strengthened during the operation of boilers and pressure vessels.

Ⅰ. To maintain the pressure gauge, the following work should be done:

1. The pressure gauge should be kept clean, the glass on the dial should be bright and clear, so that the pressure value indicated by the pointer in the dial can be easily visible. And the pressure gauge with broken glass on the dial or blurred dial scale should be abolished.

2. The connecting pipe of the pressure gauge should be blown regularly to avoid blockage, especially the connecting pipe used for gas with more oily dirt or other viscous substance.

3. You should often check whether the rotation and fluctuation of the pressure gauge pointer are normal, and whether the cock on the connecting pipe is in the fully open position.

4. The pressure gauge must be calibrated regularly, and the frequency can be based on the specific conditions:

1) After the pressure gauge has been in operation for three months, level 1 maintenance must be applied mainly to check whether the pressure gauge can return to zero position, and whether the tee cock and the water trap joint are leaking. And we must check and flush the water trap to ensure smooth flow.

2) After a year of operation, level 2 of maintenance must be applied. At this time, the pressure gauge can be disassembled and sent to the measurement department for verification and lead sealing. When we disassemble and check the trap, the threaded fasteners should be found intact. Disassemble and check the three-way cock, grind the sealing surface to ensure that it is tight without leakage, and the connection thread should be intact. Store the trap, remove the rust and paint the three-way cock.

5. When the pressure gauge is inaccurate during operation, it must be replaced in time. The replacing gauge must be a lead-sealed pressure gauge that has been verified by the metrology department and is within the validity period of the verification or a new one with a factory certificate. Before changing the meter, the three-way cock must be screwed to the position of flushing the pressure gauge, and the dirt in the trap pipe must be flushed.

The above is about the maintenance method of the pressure gauge. After the pressure gauge calibrator is used for one stage, clean the internal oil circuit regularly and replace with fresh medium to prevent the unclean material of the person being inspected from clogging the pipeline and corroding the body. Only the correct use and attention to the maintenance of the instrument can prolong the service life of the pressure gauge and the accuracy of the results.

Ⅱ. The use of the pressure gauge

Pressure gauges are commonly used mechanical equipment in the process of industrial control and measurement. Pressure gauges can be classified as mechanical and electronic pressure gauges. And mechanical pressure gauges are widely used because of their good elastic components and high mechanical strength, especially in industrial production.

The working principle of mechanical pressure meters is to indicate the pressure value through the elastic deformation of the internal elastic sensitive elements under pressure. Mechanical pressure meters generally use spring tubes, diaphragms, bellows as elastic elements. After these elastic elements deform, they will be amplified by a gear transmission mechanism to display the corresponding pressure value.

The pressure measured by a meter is relative, as the atmospheric pressure being a relative point. The result displayed by the pressure meter is also the pressure of the measured object under atmosphere. The pointer indicates the pressure value in the measuring range of the pressure meter, and the dial corresponding to the pointer is usually 270 degrees.

1. The role of pressure gauge:

Pressure is one of the most important process parameters in industrial production. If the pressure does not meet the requirements, it will affect production efficiency, reduce product quality, and even cause serious accidents. Therefore, pressure measurement has a special position in industrial production. The correct use of pressure gauges is quite necessary for accurately measuring the pressure value.

The danger of the pressure gauge itself is very low, especially when compared with the production system it monitors, its danger is almost negligible. The reason why the use of pressure meters needs to be highly valued is that pressure meters are the prerequisite for automatic interlocking devices, sensing devices and protection devices, and are the way for various reaction devices to obtain pressure information.

The role of pressure gauges in the production system is irreplaceable. The small problems in the operation of pressure meters may be hidden dangers, especially for pressure meters used for monitoring of hazardous substances such as flammable, explosive, corrosive, and toxic substances. Once the pressure measurement is wrong, it may directly lead to the leakage of hazardous substances, causing a huge environmental disaster. The safe use of pressure gauges is the responsibility of every company and every operator. This requires companies that use pressure gauges to fundamentally improve the safety of pressure gauges, reduce the risk of pressure gauge safety from the system, and provide a good environment for the use.

2. Three hidden dangers and their elimination methods of pressure gauges

Pressure gauges are common mechanical pressure measuring instruments. With the development of the instrument industry, pressure gauges have been widely used in various fields such as industrial production.

The pressure gauge can intuitively display the pressure changes in each process link, gain insight into the condition formation in the product or medium process, monitor the safety trends in the production and operation process, and build a rapid and reliable safety guarantee through automatic interlocking or sensing devices . This has played an important role in preventing accidents and protecting personal and property safety, and is called the "eye" of safety.

However, in actual production and life, pressure gauges are neglected or used illegally, which brings hidden dangers to safety. It is usually shown as below:

1). Irregular installation and configuration.

The current regulations have clear requirements for the configuration, installation, use, maintenance and inspection of pressure gauges. Problems are prominent as there are many changes to specifications as one’s wish in actual assembly. In minor parts or double (multiple) meter monitoring places, the number of settings is reduced, the disk diameter and range are not suitable for work requirements, and special instruments are used under special conditions such as flammable, explosive, toxic and corrosive.

2). Not enough attention is paid to daily use and maintenance. The inspection and clean of the device are not regular during use. There is no record of usage, and there are phenomena such as non-return to zero or severe fluctuations of the pointer, peeling off of the protective film of the anti-blast hole, corrosion of the dial or broken glass and unclean dial.

3). The inspection and verification work is not implemented. The verification period of the pressure gauge is usually once half a year. Compulsory verification is a legal measure to ensure reliable technical performance of pressure gauges, accurate value transfer, and effective safety in production. Because some users do not have a good understanding of the safety function of the pressure gauge, they do not apply for verification in advance. So exceeding the verification period is very serious. Especially the newly purchased pressure gauge can be installed and used after the verification is qualified, but the first use verification rate of the new meter is still very low.

Compared with the production system, the pressure gauge is too small to cause any accidents. However, with the pressure gauge as the major device, the automatic interlocking device, the sensing device, and the protection device as the supporting sections, and the small and subtle perception of vision, the fortress of safe construction is irreplaceable. "Thousand-mile long embankment collapsed in ant dens." Contempt and neglect of details is a sacrilege of security. As one of the safety accessories, the pressure gauge not only displays a few pressure numbers, it uses clever "eyes" to monitor the slightest "leakage hole", and always guards the door to product safety, personal safety, and environmental safety. Especially when used in dangerous places such as the production, storage, and transportation of flammable, explosive, and toxic substances, stress factors play a key role in preventing catastrophic accidents. The contribution of pressure gauges to safety cannot be underestimated. First of all, users should continuously improve their safety awareness and sense of responsibility, and truly manage and make good use of the characteristics of the pressure gauge to make it play the role of "eyes"; secondly, the testing and verification agency should actively perform the verification of the pressure gauge and downgrade it in time. Retire the pressure gauges that do not meet the usage requirements, and ensure that the measurement value is accurate and the performance is reliable; also, the supervision department must strictly supervise the use of the pressure gauge, and investigate and punish illegal operations and illegal use behaviors according to the law. Let us start from the details and the foundation, shine the "eyes" of safety, and jointly build a strong and safe long embankment.

Setting Standard Value When Digital Pressure Meter Verifies Pressure Gauge(2022年06月16日)

gaugechina — 2022-06-15T15:00:46+0900

https://www.gaugechina.com/setting-standard-value-when-digital-pressure-meter-verifies-pressure-gauge.html

1.Variation law and reason of digital pressure gauge china indication

The reason why the indication of pressure digital meter changes when setting the standard value is that the pressure test system composed of digital pressure meter and pressure calibrator is a closed non-dynamic balance system. In the process of pressurization, due to compression, gas or liquid molecules need to absorb energy, and the molecular gap decreases slowly, so the pressure will not be stable immediately, which shows that the pressure decreases slowly and will be stable for a period of time. In the process of depressurization, due to expansion, the molecules need to release energy and the molecular gap increases, which shows that the pressure increases slightly, and the pressure will not stabilize until a period of time.

2. Standard value setting method of digital pressure meter

In view of the above reasons, when setting the standard value of the digital pressure meter during the verification of the pressure gauge, a certain amount of pressure can be added to the standard value in advance during the pressurization process. After the pressurization is stopped, the indication value of the tested pressure can be read after the pressure drops to the standard value. In the process of depressurization, the pressure value can be set a certain amount less than the standard value. When the pressure rises slightly to the standard value, the detected indication value can be read.

When setting the standard value of a digital pressure meter, it is sometimes unnecessary and time-consuming to accurately display the standard value without error. When setting the standard value, several significant digits should be reserved, which is related to the absolute value of the maximum allowable error of the tested gauge. The usual practice is that after the standard value of the digital pressure meter is the number to be tested on the dividing plate of the tested gauge, the number of digits after the decimal point where the value is zero is one more than the number of digits after the decimal point of the estimated value of the tested gauge.

The correctness of the standard value setting of the above digital pressure meter is verified below:

When the digital pressure meter displays *.00* or **.00*, the maximum possible error is

25MPa×0.05%＋0.01MPa＝0.0225MPa In the above formula, +0.01Mpa is because the maximum possible value is *.009 or **.009 when the digital pressure meter displays *.00* or **.00*, and this is the maximum additional error at this time.

The maximum allowable error of the pressure gauge is

16MPa×1.6%＝0.256MPa

1/4×0.256MPa＝0.064MPa

0.0225MPa＜0.064MPa。

The above verification complies with the provisions that the absolute value of allowable error shall not be greater than 1/4 of the absolute value of allowable error of the tested general pressure meter.

For precision pressure gauges of grade 0.25 and 0.4, after the standard value of the digital pressure meter is the number to be checked on the dividing plate of the tested meter, the following values must be zero.

The following is the analysis and calculation that how many "0" should be reserved after the decimal point when setting the standard value of digital pressure meter:

Through the above analysis, the relationship between the number of "0" and the possible additional error is: additional error = 1x10-n, where n is the number of "0".

The upper limit of digital pressure meter is Pbs and the accuracy grade is Gb; The upper measuring limit of the tested pressure gauge is Ps and the accuracy grade is G. According to the verification regulation of pressure gauge

Where n is a higher integer.

Apply Formula (1) to the above 16MPa and 1.6 pressure gauges for verification and calculation

Based on the principle of taking high instead of low integer, take n = 2, and equation (1) is correct.

In formula (1), n shall not be equal to the number of "0" that can be displayed by the digital pressure meter. Because when all the digits display zeros after the decimal point, the maximum error of the digital pressure meter is its maximum allowable error. For example, the above 25MPa, 0.05 digital pressure meter can display up to 3 zeros after the decimal point, i.e. **.000. At this time, the maximum possible error is 25MPa×0.05% = 0.0125MPa without adding 0.001Mpa.

When verifying a general pressure gauge with a digital pressure gauge, due to the large allowable error of the pressure gauge, the standard value can be set within a certain range, as shown in figure 1.
Where: P -- scale number of pressure gauge hold point; Pbmin -- the minimum value that can be set for the standard value of general pressure gauge verified by digital pressure meter; Pbmax -- the maximum value that can be set for the standard value of general pressure gauge verified by digital pressure gauge.

It can be seen from equations (2) and (3) that when verifying general pressure gauges, the standard value of digital pressure gauge can be

As one of pressure gauges suppliers, we will do our best to meet all the needs of customers.

Selection and Installation of Industrial Pressure Gauges(2022年06月15日)

gaugechina — 2022-06-15T15:00:02+0900

https://www.gaugechina.com/selection-and-installation-of-industrial-pressure-gauges.html

Ⅰ. The correct selection of industrial pressure gauges

The correct selection of industrial pressure gauges china mainly includes determining the type of industrial pressure gauge, the range of the industrial pressure gauge, the range of the industrial pressure gauge, the accuracy of the industrial pressure gauge and the sensitivity of the industrial pressure gauge, the overall size of the industrial pressure gauge, and whether it needs to be far transmission and other functions, such as indication, recording, adjustment, alarm and so on.

Ⅱ. The main basis for the selection of industrial pressure gauges

Industrial pressure gauge selection and installation 1

The measurement requirements of the production process, including range and accuracy. In the case of static test (or slow change), it is stipulated that the maximum value of the measured pressure should be two-thirds of the full scale value of the pressure gauge; in the case of pulsating (fluctuating) pressure, the maximum value of the measured pressure shall be one-half of the full-scale value of the pressure gauge.

The accuracy grades of commonly used pressure detection instruments are 0.4, 1.0, 1.5 and 2.5, etc., which should be selected from the production process accuracy requirements and economic point of view. The maximum allowable error of an industrial dp pressure gauge is the product of the range of the instrument and the percentage of accuracy grade. If the error value exceeds the accuracy required by the process, it is necessary to replace a pressure gauge with a higher accuracy.

Industrial pressure gauge selection and installation 2

The properties of the measured medium, such as state (gas, liquid), temperature, viscosity, corrosiveness, degree of contamination, flammability and explosiveness, etc. Such as oxygen meter, acetylene meter, with "no oil" mark, dedicated to corrosion-resistant pressure gauges, high-temperature-resistant pressure gauges, diaphragm pressure gauges, etc. for special media.

Industrial pressure gauge selection and installation 3

Environmental conditions on site, such as ambient temperature, corrosion, vibration, humidity, etc. Such as shock-proof pressure gauges used for vibrating environmental conditions.

Industrial pressure gauge selection and installation 4

Suitable for observation by staff. Choose meters with different gauge diameters (outer dimensions) according to the location and lighting conditions of the detection meters.

What's the Difference Between Hydraulic Oil Pressure Gauges and Air Pressure Gauges?
General pressure gauge can be interoperability, which means the commonly used hydraulic oil pressure gauge and air pressure gauge can be used interchangeably as long as the range and precision can keep constant. If it is corrosive medium, you can only use air pressure gauge, such as oxygen, hydrogen, ammonia pressure gauge. Under such circumstance, hydraulic oil pressure gauge is not advisable to apply in these medium. In fact, the pressure of each working point of the hydraulic system can be observed through the hydraulic oil pressure gauge for adjustment and control. Therefore, the selection of the pressure gauge should be based on the production requirements of the use process, and specific analysis should be made for the specific situation.
