pressure transmitter
pressure transmitter Yokogawa EJX430A Gauge Pressure Transmitter
The high performance gauge 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 by TÜV as complying with SIL 2 for
safety requirement.
Output “◊”
Two wire 4 to 20 mA DC output with digital
communications, linear or square root programmable.
BRAIN or HART FSK protocol are superimposed on
the 4 to 20 mA signal.
Output range: 3.6 mA to 21.6 mA
Output limits conforming to NAMUR NE43 can be
pre-set by option code C2 or C3.
Failure Alarm (Output signal code D, E and J)
Output status at CPU failure and hardware error;
Up-scale: 110%, 21.6 mA DC or more (standard)
Down-scale: −5%, 3.2 mA DC or less
Analog output status at process abnormality (Option
code /DG6);
The result of process abnormality detected by the
advanced diagnostic function can be reflected to
an analog alert status. The following three setting
modes are available.
