EDSX5-83J Datasheet, PDF (1/12 Pages) Fuji Electric – REMOTE SEAL TYPE PRESSURE TRANSMITTER

FCX –A SERIES _{REMOTE SEAL TYPE}
PRESSURE TRANSMITTER
DATA SHEET
FKB...4
The FCX – A2 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 excellent
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 1.3kPa {0.013bar} 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. Fuji/HART^® bilingual communications protocol and
FOUNDATION™ fieldbus and Profibus™ compatibility
FCX–A2 series transmitter offers bilingual communica-
tions to speak both Fuji proprietary protocol and HART^®.
Any HART^® compatible devices can communicate with
FCX–A2. Further, by upgrading electronics FOUNDA-
TION™ fieldbus and Profibus™ are also available.
4. Application flexibility
Various options that render the FCX – A2 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
– 5-digit LCD meter with engineering unit
– Stainless steel electronics housing
– Wide selection of materials
– High temperature, high vacuum seals
5. 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.
6. 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.
