Yokogawa EJA530E-JDS4N Pressure Transmitter

Core Performance & Industrial Application

The Yokogawa EJA530E-JDS4N is an in-line mount gauge pressure transmitter from the EJA-E DPharp series.

It uses a single-crystal silicon resonant sensor to measure liquid, gas and steam gauge pressure with high stability.

It outputs a two-wire 4-20mA DC signal superimposed with HART/BRAIN digital communication for DCS acquisition and remote configuration.

Reference accuracy reaches ±0.055% of span (A/B capsule) with ±0.1% URL stability over 10 years.

It carries SIL 2 single / SIL 3 dual transmitter safety certification per IEC 61508 and supports self-diagnostics and NAMUR NE43 alarm limits.

It is widely used as spare replacement in chemical, oil & gas, power and process plant pressure monitoring.
