In the process of power plant operation, the application of transmitters is very extensive and very common, but sometimes various faults may occur. If the faults cannot be eliminated in time, it will seriously affect the safe and economic operation of the unit. Let's talk about the failure and maintenance of pressure transmitters based on our own practical experience.

Yokogawa eja530e high performance pressure transmitter adopts monocrystalline silicon resonant sensor technology, which is suitable for measuring the pressure of liquid, gas or steam. Eja530e converts the pressure into 4 ~ 20mA DC current signal output, and has the functions of fast response, remote setting, self diagnosis, etc.
