EJA110E Differential Pressure Transmitter

The EJA-E series of transmitters is Yokogawa’s most recent evolution of the DPharp family of pressure transmitters. 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 EJA110E is our standard traditional-mount differential pressure transmitter in this series.

Yokogawa’s DPharp sensor has the ability to measure the differential pressure (DP), static pressure (SP), and sensor temperature from a single sensor. Giving these three pieces of process data, Yokogawa’s transmitter can compensate the DP measurement for Temperature Effect and Static Pressure Effect in real time. This is referred to as Dynamic Compensation and improves the DP measurement accuracy. Competitor’s analog sensors can only measure DP and Sensor temperature. So, theirs can compensate for temperature Effect; but, since the SP measurement is missing, it cannot compensate for Static Pressure Effects. Save up to 20% on CAPEX spending using the DPharp’s multi-sensing capability. With our competitor’s transmitters using analog sensors, any application that requires measurement of both differential pressure (DP) and static pressure (SP) requires two separate transmitters – one to measure the DP and one to measure the SP. Yokogawa’s differential pressure transmitter with multi-sensing DPharp sensor, can measure both process variables (DP and SP) with a single transmitter. Two transmitters will always cost more than one transmitter.
