GPD80G Pressure sensor /pressure transducer/ electrical pressure transducer
GPD80G Pressure sensor(following called sensor)is a kind negative pressure transducer made up of singlechip and integrated pressure sensor components,the sensor adopts intellectualized design,new technology multiple functions ,the sensor can continuous monitoring the gas pressure of the coal gas drainage pipes ,the test pressure was changed into the corresponding frequency signal and sent to associated apparatus .
Apply to real-time continuous full range automatic detection of the gas pressure in he coal gas drainage pipes.
