EJA310E Traditional-mount Absolute Pressure Transmitter

Introduction

The EJA-E series of transmitters is Yokogawa's most recent evolution of the DPharp family. Released in 2012, it combines the ruggedness and success of the work-horse EJA-A series with the performance of the thoroughbred EJX-A series to deliver the type of product you have come to expect from Yokogawa.

The EJA310E is our traditional-mount absolute pressure transmitter in the series.

Available with HART 5/7, 1 to 5 VDC HART 7 (Low Power), FOUNDATION Fieldbus, PROFIBUS PA, or BRAIN communication.
