Coal Mine Dedicated Pressure Transmitter PCM102
Product overview
The pressure transmitter adopts a glass micro melt sensor, which is suitable for high pressure overload and can effectively resist instantaneous pressure impact. It can measure fluid media with a small amount of impurities. The built-in digital processing circuit converts the sensor millivolt signal into standard voltage and current signal output, with various structural forms and output forms, meeting the vast majority of application requirements.
