General EJX610A and EJX630A

Specifications Absolute and Gauge
Pressure Transmitter
GS 01C25F05-01EN

The high performance gauge pressure transmitter

EJX630A and absolute pressure transmitter EJX610A
feature single crystal silicon resonant sensor and are
suitable to measure liquid, gas, or steam pressure.
EJX610A and EJX630A output a 4 to 20 mA DC signal
corresponding to the measured pressure. They also
feature quick response, remote setup and monitoring
via BRAIN or HART communications, diagnostics, and
optional status output for pressure high/low alarm.
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 configuration,
with the exception of the Fieldbus and PROFIBUS
types, are certified as complying with SIL 2 for safety
requirement.
