EJA438e pressure transmitter's introduction

Views:0     Author:Site Editor     Publish Time: 2021-09-01      Origin:Site

EJA438E pressure transmitter can be used to measure high low temperature level and pressure, high vacuum, high viscosity and easy crystalline medium, it is also converted into a 4 ~ current signal output of 20 ma dc, with the functions of rapid response, remote setting and self-diagnosis.

The EJA-E series supports brain, Hart/Hart (1-5v) low power and foundation™ field bus or profibus PA communication protocols.
