In the field of chemical application, pressure transmitter plays a very important role and is widely used. There are many kinds of pressure transmitters, which can be divided into absolute pressure transmitter, gauge pressure transmitter and differential pressure transmitter according to the measurement object. According to different environmental conditions, application conditions, installation conditions and other factors, the selection of transmitter also has different requirements.

According to the national standard "Verification Regulations for Pressure Transmitters", the standard instrument used for verification should be a digital pressure test instrument that is easy to carry and has good anti-interference performance. The pressure source needs to be equipped with a pneumatic pump and a hydraulic pump.

The Type EJA310e high-performance absolute pressure transmitter is suitable for measuring liquids、gas or steam pressure, it is also converted into a current signal output of 4~20ma DC，it has quick response, remote setting, and self-diagnosis.
