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 pressure transmitter covering 50 to 10000kPa
(or 0.5 to 100 kgf/cm²). 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 tempera-
ture and overpressure substantially reduces total meas-
urement error in actual field applications.
4. Replaceable Communication Module
Fuji micro-electronics manufacturing technology offers
replaceable communication module that 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 ter-
minal side
— Full range of hazardous location approvals

— Stainless steel electronics housing
— Built-in RFI filter and lightning arrester
7. 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.)
8. 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.
