DATA SHEET
FEATURES
1. Unique hydroseal diaphragm
Permeation of hydrogen into the detecting unit through
seal diaphragm can be suppressed thanks to the unique
seal diaphragm (double coating) which employs coating
of gold and ceramic.

2. High accuracy
± 0.15% accuracy for all calibrated spans is the standard
feature for flow transmitter covering 3.2 to 130kPa (or,
320 mmH2O to 13 mH2O). Fuji’s Micro-capacitance
silicon sensor assures feature.
3. Minimum environment influence
Fuji's patented "Advanced Floating Cell" design which
protects the pressure sensor against changes in temperature, static pressure, and overpressure substantially reduces total measurement error in actual field applications.
4. Application flexibility
Various option that render the FCX-AX series suitable
for almost any process applications include.
— Analog indicator at either the electronics side or terminal side
— Full range of hazardous location approvals
— 4 12 -digit LCD meter
— Stainless steel electronics housing
— Built-in RFI filter and lightning arrester

Zero/span adjustment:
Zero is adjustable from the external adjustment screw.
The adjustment 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.
Damping:
Adjustable electrical damping.
The time constant is adjustable to 0, 0.3,
1.2, 4.8, or 19.2 seconds.
Zero elevation/suppression:
–100% to +100% of URL
Normal/reverse action:
Selectable by moving a jumper pin located on the electronics unit.
Indication:
Analog indicator or 4 12 -digit LCD meter,
as specified.
Burnout direction: If self-diagnostic detect transmitter failure, the analog signal will be driven to
either “Output Hold”, “Output
Overscale” or “Output Underscale”
modes.
Model FHF: Unless otherwise specified in the order,
the transmitter will be shipped in “Output Hold” mode.
(Output signal just before failure happens is maintained.)

“Output Hold”: Output signal is hold as the value just
before failure happens.
“Output Overscale”: Approx. 21.6mA

Loop-check output:
Transmitter can output constant signal of
4mA, 12mA, or 20mA if MODE SWITCH
is set to the loop check mode.

transmitter)
For explosionproof units (flameproof or
intrinsic safety), ambient temperature
must be within the limits specified in
each standard.
