EJA110E transmitter 4-20mA Yokogawa 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.
EJA110E features include:
- 0.055% Accuracy (0.04% Accuracy optional)
- 0.1% Stability per 10 years
- 90 ms Response Time
- Exida and TUV SIL 2 / SIL3 Certified
- MWP 2,300 psi (MWP 3,600 psi option)
- Local Parameter Setting (LPS)
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.

Features:
1-- Excellent performance and stability
The EJA series uses a formed from monocrystal silicon, a perfect material which has no hysteresis in pressure or temperature changes. The sensor minimizes overpressure, temperature change, and static pressure effects, and thus offers unmatched long-term stability.
2-- Compact and light-weight design
Half the weight of conventional models thanks to miniaturization of the casing with the amplifier ASIC, pressure cell structure, and flange. The ASIC uses the minimum number of parts and improves the reliability of the amplifier.
3-- Fieldbus communication capability
Fieldbus is a digital two-way communication system. It is a revolutionary technology for configuring instrumentation control systems and a promising successor to the standard 4 to 20 mA analog communication used in most field instruments today.
EJA series offers two types of fieldbus models, FOUNDATION fieldbus Low Voltage Mode and PROFIBUS PA devices, which ensure interoperability between and other manufactures. As for software, the EJA series incorporates two AI function blocks that compute differential and static pressures to allow flexible configuration of instrumentation.
