pressure sensor
SUS316L E differential diaphragm capsule pressure sensor
The high performance draft range differential pressure
transmitter model EJA120A outputs a 4 to 20 mA DC
signal corresponding to the measured differential
pressure.
Model EJA120A also features remote setup
and monitoring through communications with the
BRAIN™ terminal and CENTUM CS™ or XL™ or
HART® 275 host.
STANDARD SPECIFICATIONS
Refer to GS 01C22T02-00E for FOUNDATION Fieldbus
communication type and GS 01C22T03-00E for
PROFIBUS PA communication type marked with “.”
PERFORMANCE SPECIFICATIONS
The high performance draft range differential pressure
transmitter model EJA120A outputs a 4 to 20 mA DC
signal corresponding to the measured differential
pressure.
Zero-based calibrated span, linear output, wetted
parts material code ‘S’ and silicone oil.
Reference Accuracy of Calibrated Span
(including the effects of zero-based linearity, hysteresis,
and repeatability)
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 adjustable with 0.01 %
incremental resolution of span. Span may be
adjusted locally using the digital indicator with range
switch.
Mounting Position Effect
Rotation in diaphragm plane has no effect. Tilting up
to 90 will cause zero shift up to 0.4 kPa {1.6 inH2O}
which can be corrected by the zero adjustment.
