ABSOLUTE PRESSURE TRANSMITTER (DIRECT MOUNT TYPE)
FKH...5
DATA SHEET
The FCX–AIII absolute pressure transmitter (Direct mount
type) accurately measures absolute pressure and transmits
proportional 4 to 20mA signal.
The transmitter utilizes the unique micromachined capacitive silicon sensor with state-of-the-art microprocessor
technology to provide exceptional performance and
functionality.
FEATURES
1. High accuracy
0.2% accuracy for all calibrated spans is the standard
feature for all AP models covering 8.125 to 3000kPa {0.13
to 30bar} high pressure range. Fuji's micro-capacitance
silicon sensor assures this feature for all suppressed
calibration ranges without additional adjustment.
2. Minimum inventory
Electronics unit, communication module, local indicators
and electronics housing are interchangeable among all
FCX– AIII models.
3. Fuji/HART bilingual communication module
The communication module is "bilingual" to speak both
Fuji proprietary protocol and HART. Any HART compatible
devices can communicate with FCX– AIII series transmitters.
4. Application flexibility
Example features that render the FCX– AIII suitable for
almost any process applications includes:
— Full range of hazardous location approvals
— Built-in RFI filter and lightning arrester
— 5-digits LCD meter
— The maximum span of each sensor can be converted
to in different units using below factors.
5. Burnout current flexibility (Under Scale: 3.2 to 4.0mA,
Over Scale: 20.0 to 22.5mA)
Burnout signal level is adjustable using Model FXW
Hand Held Communicator (HHC) to comply with NAMUR
NE43.

Zero/span adjustment:
Zero and span are adjustable either from
the HHC(1). Zero is also adjustable externally from the adjustable screw.
Damping:
Adjustable electrical damping
The time constant is adjustable between
0.06 to 32.0 seconds.
Zero elevation/suppression:
Zero may be elevated within the specified
range limit of each sensor model.
Normal/reverse action:
Configurable 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 20.0mA to
22.5mA from HHC(1)
“Output Underscale”:
Adjustable within the range 3.2mA to
4.0mA from HHC(1)

For explosionproof units (flameproof or
intrinsic safety), ambient temperature
must be within the limits specified by
each standard.
Process: −40 to +85°C for silicone fill

Storage: −40 to +90°C
Humidity limit: 0 to 100% RH
Communication: With HHC(1) (Model FXW, consult Data
Sheet No. EDS8-47), following items can
be remotely displayed or configured.
Note: HHC’s version must be higher than
7.0 (or FXW
