China Liquid Gas Steam Explosion Proof Pressure Transducer with Display

Product overview
PCM401 flameproof pressure transmitter adopts high-performance piezoresistive silicon oil-filled pressure sensor as pressure sensitive core. Through internal ASIC, the millivolt signal of sensor is transmitted into standard long-distance transmission current signal. PCM401 can be directly connected with computer interface card, control instruments, intelligent meters or PLC conveniently. The series of products are widely used in industrial process control, petroleum, chemical, metallurgical and other industries.
The product complies with the regulations of GB3836.1-2010 "Explosive Environment Part 1: General Requirements for Equipments" and GB3836.2-2010 "Explosive Environment Part 2: Equipments Protected by Flameproof Enclosure 'd'". Explosion-proof mark Exd II B T6 applies to factories with flammable gas of II A, II B grade, T1-T6 group or environment with explosive mixture of steam and air.
Flameproof pressure transmitters operate normally at the following altitude, ambient air temperature and ambient relative humidity: altitude not exceeding 2000m; ambient air temperature -10ºC~+60ºC; relative humidity of 90% (+25ºC).
