PCM300Y Industrial Pressure&Level Transmitter

Features 

 316L stainless steel isolation diaphragm structure  

 High precision, all stainless steel structure

 Micro amplifier, voltage and current signal output

 Diversified forms and structures, easy to install and use

Wide range, can measure absolute pressure, gauge pressure and sealed gauge pressure

Vibration and shock resistance

The PCM300Y submersible pressure transmitter uses a diffused silicon pressure sensor as the sensitive element, and the built-in processing circuit converts the sensor's millivolt signal into a standard voltage and current signal output, which can be directly connected to the computer, control instrument, display instrument, etc. It uses the high-stability and high-reliability piezoresistive pressure sensor as well as high-performance dedicated circuit of transmitter. The overall performance is stable and reliable, and can carry out the long-distance signal transmission.
