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.
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.
