M20 Pressure Sensor for Industrial Gas Oxygen Hydrogen Nitrogen...

M20 pressure sensor / transmitter is developed based on series of piezo-resistive measuring cell manufactured by Micro Sensor itself. M20 has compact size, great integration of electronic parts, comprehensive options of connection and signal output, full scale temperature compensation. It is extremely cost-effective while maintaining a high level of reliability.

With flexibility of self-made measuring cells, M20 is compatible to measure different industrial gas, like oxygen (oxygen cleaning follows CGA G-4.1, ASTM G93-03), hydrogen (gold plated diaphragm against hydrogen permeation), nitrogen, carbon dioxide, argon, helium and acetylene.

With fully welded wetted oparts, no sealing O-ring, M20 has wide compatibility with different medium. Approved with UL, CE, RoHS, REACH, M20 is also cost-effective and suitable for general industries, including water treatment, building automation, pump stations, HVAC, irrigation, pneumatic tools, etc.
