The high performance absolute and gauge pressure transmitter EJA510E and EJA530E feature single crystal silicon resonant sensor and are suitable to measure liquid, gas, or steam pressure. EJA510E and EJA530E output a 4 to 20 mA DC signal corresponding to the measured pressure. It also features quick response, remote setup and monitoring via BRAIN or HART communications and self diagnostics. FOUNDATION Fieldbus, PROFIBUS PA and 1 to 5 V DC with HART (Low Power) protocol types are also available. EJA-E series models in their standard configuration, with the exception of the Fieldbus, PROFIBUS and Low Power types, are certified as complying with SIL 2 for safety requirement.

The EJA510E is a high-performance in-line mount absolute pressure transmitter that represents the latest evolution of the renowned DPharp sensor technology. Launched in 2012, this transmitter seamlessly combines the rugged reliability of the proven EJA-E series with the superior performance of the premium EJX-A series, delivering the precision and durability that industrial users have come to expect from Yokogawa's OpreX Measurement product lineup.
At the core of the EJA510E lies Yokogawa's proprietary DPharp digital sensor, which utilizes advanced single-crystal silicon resonance technology. Unlike traditional analog sensors, the DPharp sensor directly outputs digital signals, eliminating the need for analog-to-digital conversion and significantly reducing measurement errors. This cutting-edge sensor technology ensures twice the performance and stability of competing analog sensors, providing consistent, reliable, and accurate pressure measurements for critical industrial processes.
