China Flameproof Pressure Transmitter for Flammable Explosive Environment

Product overview
PCM301 Flameproof Pressure Transmitter is specially designed for explosion-proof places. It has obtained Exd II BT6 certification.
PCM301 adopts integrated all-welded structure and high-stability piezoresistive silicon pressure sensor with high-performance dedicated amplifier circuit. The isolation and explosion-proof requirements are met after repeatedly stainless steel welding. PCM301 has advantages of high strength, small size, excellent anti-vibration performance, anti-mildew and moisture-proof design, which can be used in harsh environments for long term. PCM301 is widely used in petroleum machinery, chemical machinery, pumps, compressors, electric power, boilers, natural gas and various explosion-proof places.
