EDSX5-74 Datasheet, PDF (1/10 Pages) Fuji Electric – FCX – AX SERIES SMALL FLANGE REMOTE SEAL TYPE PRESSURE TRANSMITTER

FCX – AX SERIES SMALL FLANGE REMOTE SEAL TYPE
PRESSURE TRANSMITTER
DATA SHEET
FHW, FKW...3
The FCX –AX Series small flange remote seal type pres-
sure 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 excellent
reliability in high temperature and highly corrosive process
conditions.
FEATURES
1. Directly connectable to 1-1/2in and 2in flanges
The transmitter is connectable to 1-1/2in and 2in pipes
without a reducer.
2. Connectable to 1/2in and 3/4in pipes
Use of direct mounting adapter allows the transmitter to
be connected to the following process.
1/2in and 3/4in flanges
Screw connection 1/2-14NPT, 3/4-14NPT, Rc1/2, Rc3/4
3. Minimum environmental influence
The "Floating Cell" design which protects the pressure
sensor against changes in temperature, and overpressure
substantially reduces total measurement 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 protocl, 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 transmit-
ters.
6. 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
— 4^1/2 -digits LCD meter
— Stainless steel electronics housing
— Wide selection of materials
— High temperature, vacuum seals
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.
