Pressure Sensor for Oxygen Pressure Measurement

Oxygen plays an important role in many fields like the smelting process, chemical industry, national defense industry, and health care, but it is highly prone to combustion and explosion during the oxygen production and usage process.

Based on the theory that burning or explosion is caused by three factors-combustibles, oxidants, and ignition source, the high-purity high-pressure oxygen transported in the oxygen pipeline is a very strong oxidant. The higher the purity, the higher the pressure will be, thus the oxygen will be more oxidizing and dangerous. The potential ignition sources that cause combustion or explosion are like following: friction, the heat of compression, impact, arc or resonance, etc.

During the construction of the industrial oxygen pipelines, they should be cleaned in various processes like derusted, scrubbed, sandblasted, purged, degreased and pickled to remove oil and impurities from the pipeline to meet the conditions for transporting oxygen. The pipelines should only be accepted and put into use after passing the terms in accordance with relevant standards.

Pressure Sensors for Oxygen Pressure Measurement

For oxygen pressure measurement, the instruments should be clean with inert oil not only improves the safety level but also greatly reduces the economic and time loss risks caused by maintenance or failure replacement.

For AST100，AST101，AST103, and other oxygen pressure sensors, AST103 differential pressure transmitter for oxygen pressure measurement, the sensing part is filled with Fluorolube® oil inside. Meanwhile, the production uses an oil-free process, and oxygen pressure sensors and transmitters are cleaned and packaged according to the oxygen standard cleaning process.

The pressure sensors mentioned above can be used in hazardous locations including flameproof, intrinsically safe products, and in factories and hospitals which involving oxygen pressure measurement.
