Pressure Transmitters for Special Gas Pressure Measurement

-

Apart from temperature, pressure is the second most important measurement measured in industrial processes. Measuring pressure allows manufacturers to control the quality of the product and the overall dynamic process. Additionally, pressure is crucial in most physical applications, from overall planetary functions and industrial processes to human needs.

So how can we measure pressure during industrial applications? With pressure transmitters, manufacturers can get accurate readings of pressure in any industrial application. We will delve into the world of pressure transmitters for special gas measurement.

Gases have different properties and characters, requiring special transmitters to give readings. Below are several products to help you understand what chlorine, oxygen, hydrogen, and other pressure transmitters can offer.

Pressure Transmitters for Special Gas Pressure Measurement

Hydrogen pressure transmitter

Hydrogen is a common gas used in many industrial processes like refining petroleum, processing, food treatment, etc. It’s highly combustible, odorless, and colorless. Hydrogen has a small atom meaning it diffuses through the lattice’s diaphragm and thus penetrates the cavity containing silicone oil.

This damages the sensor in the long run. However, this is easily avoidable by using a gold-coated diaphragm since gold features low permeability. The pressure transmitter below is a great example of a special transmitter for measuring hydrogen pressure. Check out the transmitters from microsensorcorp.com.

MPM280AU

The MPM280AU Hydrogen Pressure Sensor is a suitable hydrogen pressure transmitter that features an isolated structure. its corrugated diaphragm is gold plated to decrease permeability. It’s the perfect pressure sensor to stop hydrogen from diffusing and penetrating the cavity containing silicone oil. It also features a sealed gauge for better and accurate readings. The MPM280AU is the best type of sensor for all hydrogen pressure measurements with the added ability of durability.

Oxygen pressure transmitter

Dry air contains approximately 21% oxygen.  Individuals obtain oxygen through liquid air in industries like aviation, energy, chemical, metalworking, water treatment, and medicine. Apart from compressed oxygen, which is flammable and explosive, oxygen supports combustion.

Most industrial processes involve heat, which can damage normal pressure transmitters. A clean pressure transmitter containing inert oil-filled is the best option. This device lowers the risk of time and economic loss by replacing failed parts. 

MDM4901FL

The MDM4901FL is a differential pressure transmitter made to measure oxygen pressure. To meet the standards for oxygen measurement, the device is created using an oil-free technique. The device is clean throughout and contains Fluorolube Oil, that aids in successfully stopping the oxidation process between oxygen and silicon. Also, it lowers the possibility of an explosion.

Chlorine pressure transmitter

Chlorine is a yellow-green gas that oxidizes with a majority of compounds. Metals like steel, copper, nickel, and iron can withstand dry chlorine; however, when chlorine gas is diluted with a little water, it creates hydrochloric acids, which are quite corrosive to most metals.

To provide dependable and precise measurement: appropriate anti-corrosive material and diaphragm must be used to create the pressure transmitters.

Conclusion

Depending on the application, various gas pressure measuring demands and specifications may apply. Therefore, getting the best pressure transmitter is crucial to ensure the optimum production of goods or production processes.
