FCX – AX SERIES PRESSURE TRANSMITTER
DATA SHEET
FHG,FKG...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
tech- nology to provide exceptional performance and func-
tionality.
FEATURES
1. High accuracy
0.07% accuracy for all calibrated spans is a standard fea-
ture for pressure transmitter covering 6.4 to 50000kPa
{0.064 to 500bar}. Fuji’s micro-capacitance silicon sensor
assures this accuracy for all elevated or suppressed cali-
bration ranges without additional adjustment.
2. Minimum environmental influence
The “Advance 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 trans-
mitters.
5. Application flexibility
Various options that render the FCX – AX suitable for al-
most 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

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.
