pressure sensor
pressure sensor Tantalum V module pressure transmitter sensor
The high performance differential pressure transmitter
model EJA110A can be used to measure liquid, gas,
or steam flow as well as liquid level, density and
pressure. It outputs a 4 to 20 mA DC signal corresponding
to the measured differential pressure. Model
EJA110A 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
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.
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.
