EDSX5-94H Datasheet, PDF (1/12 Pages) Fuji Electric – REMOTE SEAL TYPE PRESSURE TRANSMITTER

DATA SHEET
REMOTE SEAL TYPE
PRESSURE TRANSMITTER
FKB...5
The FCX -AIII pressure transmitter accurately measures
gauge pressure and transmits a proportional 4 to 20mA sig-
nal.
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
feature for all GP models covering 1.3kPa {0.013bar}
range to 50000kPa {500bar} high pressure range. 0.1%
accuracy is available as option. Fuji’s micro-capacitance
silicon sensor assures this accuracy for all elevated or
suppressed calibration ranges without additional adjust-
ment.
2. Minimum environmental influence
The “Advanced Floating Cell” design which protects
the pressure sensor against changes in temperature,
and overpressure substantially reduces total measure-
ment error in actual field applications.
3. Fuji/HART^® bilingual communications protocol
FCX -AIII series transmitter offers bilingual communica-
tions to speak both Fuji proprietary protocol and HART^®.
Any HART^® compatible devices can communicate with
FCX -AIII.
4. Application flexibility
Various options that render the FCX -AIII suitable for
almost any process applications include:
− 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 4.0mA,
Over Scale: 20.0 to 22.5mA)
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.
