Product Overview
PCM301J Pressure Transmitter is specially designed for explosion-proof places,which 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. PCM301J 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. PCM301J is widely used in petroleum machinery, chemical
machinery, pumps, compressors, electric power, boilers, natural gas and various explosion-proof places.

Media condition
In the liquid containing particles, nozzle clogging may occur. The vertical mounting of pressure transmitter minimizes the risk of clogging because the
flow of fluid happens in initial start only, the volume of the rear of the nozzle is fixed and the nozzle has a relatively large aperture (1.2 mm).
The effect of medium viscosity on response time is small. Even if the viscosity reaches 100 CST, the response time will not exceed 4 ms.
Note: Torque depends on various factors such as material of gasket, supporting materials, lubrication of thread and pressure.
