ENGLISH

Yokogawa EJX430A

Traditional-mount Gauge Pressure Transmitter

The high performance gauge pressure transmitter EJX430A features single crystal silicon resonant sensor and is suitable to measure liquid, gas, or steam pressure.
The EJX430A outputs 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 diagnostics.
The multi-sensing technology provides the advanced diagnostic function to detect such abnormalities as an impulse line blockage or heat trace breakage.
FOUNDATION Fieldbus and PROFIBUS PA protocol types are also available.
All EJX series models in their standard confi guration, with the exception of the Fieldbus and PROFIBUS types, are certifi ed as complying with SIL 2 for safet requirement.
