PM428 flat film diaphragm pressure transducer

PM428 diaphragm pressure transducer adopts high-precision, high-temperature fixed-performance sensitive chip with imported stainless steel isolation diaphragm. After laser resistance adjustment and certain signal processing, it outputs industrial standard signal 4~20mA or 0~10mA.

PM428 flat film diaphragm pressure transducer

PM428 diaphragm pressure transducer, also called  diaphragm pressure transmitter which adopts high-precision, high-temperature fixed-performance sensitive chip with imported stainless steel isolation diaphragm. After laser resistance adjustment and certain signal processing, it outputs industrial standard signal 4~20mA or 0~10mA.

Flat film diaphragm pressure transducer application

The transmitter is widely used in petroleum, chemical, metallurgy, electric power, environmental protection and other fields for the automatic measurement and control of corrosive gases, liquids, steam gauge pressure and absolute pressure.
