Electric resistance transmissible pressure gauge
◎Application Description
Differentially transmissible pressure gauge is safe anti-explosive gauge which is mainly used in measuring the pressure of the gas and liquid which have no corrosion function to copper and steel. When attached the damper, it can measure the pressure of the media which has sharp pulsation and concussion character. when attached the diaphragm, it can measure the pressure of media which has high viscosity, strong corrosion character. This gauge can not only indicate the pressure measurement, but also continuously output the 4-20mA direct current signal which is linear to the pressure measurement. It also can connected with the showing, recording, adjusting gauge and become a auto-recording,adjusting,controlling system. This gauge is suited for the oil and chemical industry, metallurgical industry, power station and so on.
This gauge accord with the request of the GB3836.4-83 and have procured the anti-explosion qualified certification through the anti-explosion examine DPT.
