FCX – C SERIES
ABSOLUTE PRESSURE TRANSMITTER
DATA SHEET
FHH, FKH
The FCX –C absolute pressure transmitter 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 13 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 –C models.
3. Replaceable Communication Module
Fuji micro-electronics manufacturing technology offers
replaceable communication module that makes FCX-AC
transmitter very unique design. In case of change in
communication protocol all that needs to be done is just
replace the module and the transmitter gets upgraded to
the new version.
4. 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-A/C series transmitters.
5. Application flexibility
Example features that render the FCX –C suitable for
almost any process applications includes:
— Analog indicator at either the electronics side or terminal side
— Full range of hazardous location approvals
— Built-in RFI filter and lightning arrester
— 4 12 -digits LCD meter
— The maximum span of each sensor can be converted to
in different units using below factors.

Zero/span adjustment:
Model FHH: Zero is adjustable from an external adjustable screw.
The adjustable screw can also function
to adjust span when MODE SWITCH (located on the electronics unit) is in the span
mode. INHIBIT mode to disable the adjustable screw is also available.
Model FKH: Zero and span are adjustable either from
the HHC. Zero is also adjustable externally from the adjustable screw.
Damping:
Adjustable electrical damping
Model FHH: The time constant is adjustable to 0, 0.3,
1.2, 4.8, or 19.2 seconds.
Model FKH: The time constant is adjustable between
0 to 38.4 seconds. (9 steps)
Zero elevation/suppression:
Zero may be elevated within the specified
range limit of each sensor model.
Normal/reverse action:
Model FHH: Selectable by moving a jumper pin located
on the electronics unit.
Model FKH: Configurable from HHC.
Indication:
Analog indicator or 4 1 -digit LCD meter,
2
as specified.
Burnout direction:
Output hold
Output 21.6mA selectable
Output 3.8mA
Model FHH: Unless otherwise specified, the output is
in hold position.
Model FKH: Selectable from HHC.

Loop-check output:
Model FHH: Transmitter can output constant signal of
4mA, 12mA, or 20mA if MODE SWITCH
is set to the loop check mode.
Model FKH: Transmitter can be configured to provide
constant signal 3.8mA through 21.6mA
by HHC.
Temperature limit: Ambient: –40 to +85°C
(–20 to +80°C for LCD indicator)
(–40 to +60°C for arrester option)
For explosionproof units (flameproof or
intrinsic safety), ambient temperature
