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.

Mounting Position Effects
Tilting up to 90 degree will cause zero shift up to 0.5
kPa (2.0 inH2O), which can be corrected by the zero
adjustment.
Response Time (All capsules) “◊”
90 ms

When amplifier damping set to zero and including
dead time of 45 ms (nominal)
Minimum Pressure at Calibration*
L capsule: 130 Pa abs (1 mmHg abs)
M, A and B capsules: 2.7 kPa abs (20 mmHg abs)
* : If one or two of the calibration points are smaller
than the above value, the above pressure is used
for testing.

In case all of the calibration points are greater
than the limit, only the pressure of upper range
value (URV) is applied for testing.
Specifying option code /S1 with M or A capsule
will lower the limit to 130 Pa abs.
/S1 is recommended for M capsule when
the specified upper range value (URV) is not
exceeding 3.4 kPa abs.
