Gas pressure transducer is a special sensor that converts gas pressure into current and voltage signals.

For gas pressure measurement the solution of pressure sensor is used to accomplish the significance of measurement.

Pressure sensors for gas pressure measurement are mainly conversion devices used to measure the absolute pressure of gases.

It can be used for pressure measurement in terms of blood pressure, wind pressure, pipeline gas, etc. It has a stable and reliable performance.

It is mainly suitable for physical experiments related to gas pressure. Such as gas laws, etc. It can also be used in biological and chemical experiments to measure the pressure of dry, non-corrosive gases.

How does gas pressure sensor work?

In short, a pressure sensor converts pressure into a small electrical signal, which is sent and displayed. Therefore, these are also commonly referred to as pressure transmitters. Two common signals used are 4 to 20 mA signals and 0 to 5 volt signals.
Most pressure sensors work using the piezoelectric effect. This is when the material generates a charge in response to stress. This stress is usually compressive, but may be twisted, bent, or vibrated.

Pressure sensors detect pressure and can determine the amount of pressure by measuring the charge.

The pressure sensor needs to be calibrated in order to know what voltage or milliamp (mA) signal corresponds to what pressure. This is the basic “zero” and “span” calibration or minimum and maximum, which is a common job for maintenance personnel.

The price of gas pressure Transducers is mainly affected by the following factors:

  1. Measuring medium
  2. Does the gas contain particles?
  3. Gas temperature
  4. Gas corrosive
  5. Explosion-proof performance
  6. Interface size
  7. Signal output, etc.

Gas pressure Transducer price reference range: USD80-800.00/pc

Natural gas pressure Transducer is 4-20mA current output sensors for monitoring the pressure of natural gas. Measure very low inlet and output pressure or very high natural gas bottle pressures. Where there is the potential for natural gas to be present in the local atmosphere, special approval options such as ATEX intrinsic safety are available.

What pressure sensor is used on the natural gas pipeline?

  1. Natural gas pipelines are pipelines that transport natural gas (including associated gas produced in oil fields) from mining sites or treatment plants to urban gas distribution centers or industrial enterprise users, also known as gas pipelines.
    Using natural gas pipelines to transport natural gas is the only way to transport large amounts of natural gas on land. Natural gas pipelines account for about half of the total pipeline length in the world.
  2. Residential gas inlet pipes should be installed in non-residential rooms such as kitchens, corridors, and enclosed balconies connected to the kitchen (the balconies should be closed when transporting wet gas in cold areas) and other non-residential rooms that are convenient for maintenance. When it is really difficult, it can be introduced from the stairwell, but metal pipes and inlet pipe valves should be installed outdoors.
  3. The gas introduction pipes of commercial and industrial enterprises should be installed in the rooms or gas meter rooms where gas is used.
  4. The gas introduction pipe should be introduced through the wall along the ground on the outer wall. The upper bend of the outdoor exposed pipe section should be installed with no less than DN15 cleaning tee and wire plug, and treated with anti-corrosion treatment. Keep warm when transporting wet gas in cold areas. The introduction pipe can be buried into the room through the outer wall or foundation of the building. When the introduction pipe penetrates the wall or foundation and enters the building, it shall exit the indoor ground within a short distance, and shall not be laid horizontally under the indoor ground.

The sensors used to detect natural gas pipelines can be used to detect the pressure of natural gas pipelines with explosion-proof verification and regular gas pipeline pressure sensors and gas pressure Transducers.

The air pressure sensor is used to measure the absolute pressure of the gas. It is mainly suitable for physical experiments related to gas pressure, such as gas laws, etc. It can also measure dry and non-corrosive gas pressure in biological and chemical experiments.

The air pressure sensor is mainly used to measure the pressure of the gas. One of the atmospheric pressure sensors is usually used to measure changes in weather and use the corresponding relationship between air pressure and altitude for altitude measurement.

The air pressure sensor is a detection device that can feel the measured information, and can transform the detected and felt information into electrical signals or other required forms of information output according to a certain rule to meet the needs of information transmission, processing, and Storage, display, recording and control requirements.

Pressure transmitter types include gauge pressure, absolute pressure, and differential pressure. Gauge pressure refers to the pressure that is less than or greater than atmospheric pressure based on the atmosphere. Absolute pressure refers to the absolute zero pressure as the reference and is higher than the absolute pressure. Differential pressure refers to the difference between two pressures.

According to the working principle of the pressure transmitter:

  • Strain Gauge Pressure Transducers
  • Capacitance Pressure Transducers
  • Potentiometric Pressure Transducers
  • Resonant Wire Pressure Transducers

Q&A

What is pressure transducer used for?

The main function of a pressure transmitter is to transmit pressure signals to electronic equipment. The pressure is then displayed on the computer. For example, the mechanical signal of water pressure is converted into an electronic signal such as voltage or current (usually 0-5V or 4-20mA). Pressure and voltage or current have a linear relationship. It is generally proportional, so the voltage or current output by the transmitter increases with increasing pressure.
A pressure transmitter is a sensor commonly used in industrial practice. It is widely used in various industrial automatic control environments. Involving water conservancy and hydropower, railway transportation, intelligent buildings, production control, aerospace, military industry, petrochemicals, oil wells, electric power, ships, machine tools, pipelines and many other industries. The pressure transmitter workshop must be in direct contact with the measured medium. Often run in high temperature, low temperature, corrosion, vibration, shock and other environments. Whether it works normally on the job site depends not only on the quality of the product. It also depends on optimized engineering design and reasonable model configuration. And proper installation and maintenance. Pressure transmitters are a key element in the fluid industry.
Pressure transmitters are mainly used in the following areas:
1.Petroleum, petrochemical, chemical industry, supporting with throttling devices. Provides accurate flow measurement and control. Measures pressure and level in pipes and tanks.
2.Electric power, city gas, and other companies. Places requiring high stability and high accuracy measurement.
3.Pulp and papermaking are used in places that require chemical-resistant liquids and corrosion-resistant liquids.
4. Steel, non-ferrous metals, ceramics, used in furnace pressure measurement and other places requiring high stability, high precision measurement and other places. It is used in places where stable measurement is required under strict control (temperature, humidity, etc.).
5. Machinery and shipbuilding, used to strictly control the place where high precision is required for stable measurement.
In general, the pressure transmitter is mainly used to measure the pressure of the medium and the liquid level.
