PRESSURE TRANSMITTER
FHG...4
DATA SHEET
The FCX – A2e pressure transmitter accurately measures
gauge pressure and transmits a proportional 4 to 20mA
signal.
The transmitter utilizes a unique micromachined capacitance silicon sensor with state-of-the-art microprocessor
technology to provide exceptional performance and functionality.
FEATURES
1. High accuracy ±0.1%
0.1% accuracy is a standard feature. Fuji’s micro-capacitance silicon sensor assures this accuracy for all elevated
or suppressed calibration ranges without additional adjustment.
2. Minimum environmental influence
The “Advance Floating Cell” design which protects the
pressure sensor against changes in temperature, and
overpressure substantially reduces total measurement
error in actual field applications.
3. Fuji/HART® bilingual communications protocol
FCX–A2e series transmitter offers bilingual communications to speak both Fuji proprietary protocol and HART®.
Any HART® compatible devices can communicate with
FCX–A2e.
4. Application flexibility
Various options that render the FCX – A2e suitable for almost any process applications include:
– Analog indicator at either the electronics side or terminal side
– Full range of hazardous area approvals
– Built-in RFI filter and lightning arrester
– 5-digit LCD meter with engineering unit
5. Burnout current flexibility (Under Scale: 3.2 to 3.8mA,
Over Scale: 20.8 to 21.6mA)
Burnout signal level is adjustable using Model FXW Hand
Held Communicator (HHC) to comply with NAMUR NE43.
6. Dry calibration without reference pressure
Thanks to the best combination of unique construction
of mechanical parts (Sensor unit) and high performance
electronics circuit (Electronics unit), reliability of dry
calibration without reference pressure is at equal level
as wet calibration.

Zero/span adjustment:
Zero and span are adjustable from the
HHC(1). Zero and span are also adjustable
externally from the adjustment screw
(span adjustment is not available with 9th
digit code "L, P, Q, S").
Damping:
Adjustable from HHC or local adjustment
unit with LCD display.
The time constant is adjustable between
0.12 to 32 seconds.
Zero elevation/suppression:
Zero can be elevated or suppressed within
the specified range limit of each sensor
model.
Normal/reverse action:
Selectable from HHC(1).
Indication:
Analog indicator or 5-digit LCD meter, as
specified.
Burnout direction: Selectable from HHC(1)
If self-diagnostic detect transmitter failure, the analog signal will be driven to either “Output Hold”, “Output Overscale”
or “Output Underscale” modes.
“Output Hold”:
Output signal is hold as the value just before failure happens.
“Output Overscale”:
Adjustable within the range 20.8mA to
21.6mA from HHC(1)
“Output Underscale”:
Adjustable within the range 3.2mA to
3.8mA from HHC
