Pressure Sensor and Transmitters for Special Gas Pressure Measurement
2018-08-29

Gas pressure measurement widely exists in industrial process control fields to achieve better controlling and monitoring.

Different gases are different in nature, therefore different pressure sensors and transmitters are required for different gas pressure measurement. Several products are introduced below for pressure measurement of oxygen, hydrogen and Chlorine.


Oxygen Pressure Measurement




There are around 21% oxygen by volume in the dry air. People extract oxygen from liquefied air and use oxygen in fields such as aerospace & aviation, energy, chemical, metallurgy, medical pharmacy, water treatment etc. Except compressed oxygen, oxygen itself is not flammable or explosive, but combustion-supporting. For oxygen pressure measurement, the clean pressure sensors and transmitters with inert oil-filled are safer choices, which greatly reduces the risk of economic and time loss caused by maintenance or failure replacement.


Products for Oxygen Pressure Measurement




MDM4901FL differential pressure transmitter is designed for oxygen pressure measurement. The whole product is clean and it is Fluorolube® oil-filled which helps to prevent the oxidation reaction between the silicon oil and the oxygen, and the occurrence of an explosion effectively.

Meanwhile, MDM4901FL differential pressure transmitter is produced under oil-free process to meet the oxygen measurement requirements.

Besides MDM4901FL, we have other pressure sensors and transmitters for oxygen pressure measurement with intrinsic safe type, battery power type and wireless monitoring type.

 

Hydrogen Pressure Measurement




Hydrogen (H2), is a gas that is extremely flammable, colorless and odorless under normal temperature and pressure. Hydrogen has strong reducibility and is widely used in chemical, electronics, automotive, aerospace and other industries.

Since the atom of hydrogen is very small, it will diffuse through the lattice of the diaphragm (generally stainless steel), thereby penetrating into the cavity filled with the silicon oil. After long-term use, the infiltrated gas will damage the sensor.

While gold has low penetrability than stainless steel, gold- plated diaphragm is an effective way to preventing hydrogen penetrating.


Products for Hydrogen Pressure Measurement




MPM4961HL pressure transmitter is specialized for hydrogen pressure measurement. It has gold-plated diaphragm which helps to prevent hydrogen penetrating, ensuring long term and stable performance.


Chlorine Pressure Measurement




Chlorine gas (Cl2) is a yellow-green toxic gas and a strong oxidant that can oxidize with most substances.

Generally, steel, iron, copper, nickel, etc. are resistant to dry chlorine, but once chlorine gas is mixed with a small amount of water, it produces hypochlorous acid and hydrochloric acid, which are highly corrosive to most metals. So the pressure sensors and transmitters for chlorine pressure measure must has special anti-corrosive housing and diaphragm materials to ensure reliable and accurate measurement.


Products for Chlorine Pressure Measurement




Our MPM4961CL is a pressure transmitter specialized for chlorine pressure measurement. The pressure diaphragm and housing are made of full Titanium alloy to prevent chlorine media from corroding the measuring products, ensuring reliable and stable operation. At the same time, inert oil is filled in the pressure sensors as transferring media from pressure diaphragm to sensing die.
