Yokogawa EJX530A Transmitter

Core Performance & Industrial Application

The Yokogawa EJX530A is the EJX-A premium DPharp gauge pressure transmitter for liquids, gas and steam; monocrystalline resonant-sensor technology.

Reference accuracy ±0.04% of span; ±0.1% of URL stability over 15 years; 90 ms response; rangeability 25:1 (A) / 50:1 (B/C/D); SIL2/SIL3 per Exida and TÜV.

4-20 mA DC with HART (or BRAIN/FF/PA per suffix); local parameter setting (LPS) without hand communicator; 1/2 NPT process connection.

It measures gauge pressure in process and utility loops as spare replacement on installed EJX-A systems.
