pressure transmitter
Yokogawa EJX440A Gauge pressure transmitter
The high performance gauge transmitter EJX440A features single crystal silicon resonant sensor and is suitable to measure liquid, gas, or steam pressure. The EJX440A 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 PROFIBUSPA protocol types are also available.
All EJX series models in their standard configuration, with the exception of the Fieldbus and PROFIBUS types, are certified by TÜV as complying with SIL 2 for safety requirement.
PERFORMANCE SPECIFICATIONS
Zero-based calibrated span, linear output, wetted
parts material code ‘S’ and silicone oil, unless
otherwise mentioned.
For Fieldbus and PROFIBUS PA communication
types, use calibrated range instead of span in the
following specifications.
