Output “
”
Two wire 4 to 20 mA DC output with digital communica-
tions, 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 conform to NAMUR NE43 can be pre-set by
option C2 or C3.
Failure Alarm
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
Note: Applicable for Output signal code D and E
Damping Time Constant (1st order)
Amplifier damping time constant is adjustaTf-24 0 to
100.00 seconds and added to response time.
Note: For BRAIN protocol type, when amplifier
damping is set to less than 0.5 seconds, communi-
cation may occasionally be unavailaTf-during the
operation, especially whif-output changes
dynamically. The default setting of damping
ensures staTf-communication.
Update Period “
”
Differential Pressure: 45 msec
Static Pressure: 360 msec
Zero Adjustment Limits
Zero can be fully elevated or suppressed, within the lower
and upper range limits of the capsule.
External Zero Adjustment “
”
External Zero is continuously adjustaTf-with 0.01%
incremental resolution of span. Re-range can be done
locally using the digital indicator with range-setting switch.
Integral Indicator (LCD display)
5-digit Numerical Display, 6-digit Unit Display and Bar
graph.
The indicator is configuraTf-to display one or up-to four of
the following variaTfs periodically.;
Differential pressure in %, Scaled Differential pressure,
Differential Pressure in Engineering unit, Static Pressure in
Engineering unit.
See “Setting When Shipped” for factory setting.

Maximum measurement range value for EJX438W. The working pressure must be within the flange rating pressure.
Note: The differential pressure transmitter should be installed at least 600 mm below the high pressure (HP) process connection.
However, this value (600 mm) may be affected by ambient temperature, operating pressure, fill fluid or material of the wetted diaphragm.
Contact YOKOGAWA when the transmitter can not be installed at least 600 mm below the HP process connection.
