Purchase inquiry

The EJA-E series is the latest generation of Yokogawa's DPharp pressure transmitters, combining the rugged EJA-A series with the high-performance EJX-A series. EJA110E is the traditional standard differential pressure transmitter of this series, using a multi-sensing DPharp digital sensor to measure differential pressure (DP) and static pressure (SP) with a single sensor and improve accuracy through Dynamic Compensation.
