FCX – AX SERIES
DIFFERENTIAL PRESSURE TRANSMITTER
Hydroseal® Diaphragm Version
FHC, FKC...3
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 differential pressure (flow) transmitter
covering 3.2 to 130kPa (or 320mm to 13 mH2O). Fuji's
Micro-capacitance silicon sensor assures this 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. Replaceable Communication Module
Fuji micro-electronics manufacturing technology offers
replaceable communication module the makes FCX-AX
transmitter very unique in design. In case of change in
communication protocol, all that needs to be done is
just to replace the module and the transmitter gets upgraded to the new version.
5. 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-AX
series trans-mitters.
6. Application flexibility
Various options 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
7. Programmable output Linearization Function
In addition to Linear and Square Root, output signal
can be freely programmable.
(Up to 14 compensated points at approximation.)
(Available for amplifier unit from version 24 and FXW(HHC) version
5.3.)
8. 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.
(Available for amplifier unit from version 24 and FXW(HHC) version
5.3.)
9. 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.
