PRESSURE TRANSMITTER
DATA SHEET
FHB, FKB...3
The FCX – AX pressure transmitter accurately measures
gauge pressure and transmits a proportional 4 to 20mA signal.
The transmitter utilizes a unique micromachined capaci-
tance silicon sensor with state-of -the-art microprocessor
technology to provide exceptional performance and func-
tionality.
Totally welded construction of the seals assures excel-
lent reliability in high temperature and highly corrosive
process conditions.
FEATURES
1. High accuracy
0.2% accuracy for all calibrated spans is a standard fea-
ture for all GP models covering 6.4kPa{0.064bar} range
to 50000kPa{500bar} high pressure range. 0.1% accu-
racy is available as option. Fuji's micro-capacitance sili-
con sensor assures this accuracy for all elevated or sup-
pressed calibration ranges without additional adjustment.
2. Minimum environmental influence
The "Advanced Floating Cell" design which protects the
pressure sensor against changes in temperature, and
overpressure substantially reduces total measurement
error in actual field applications.
3. 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.
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 – AX series transmit-
ters.
5. Application flexibility
Various options that render the FCX – AX suitable for
almost any process applications include:
— Analog indicator at either the electronics side or ter-
minal side
— Full range of hazardous area approvals
— Built-in RFI filter and lightning arrester

— Stainless steel electronics housing
— Wide selection of materials
— High temperature, high vacuum seals
6. 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.)
7. 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.

Remark: To minimize environmental influence, span should be greater
than 1/40 of the max. span in most applications.
