EDSX6-117I Datasheet, PDF (1/12 Pages) Fuji Electric – REMOTE SEAL TYPE DIFFERENTIAL PRESSURE TRANSMITTER

REMOTE SEAL TYPE
DIFFERENTIAL PRESSURE TRANSMITTER
DATA SHEET
FKD...4
The FCX – A2 differential pressure transmitter accurately
measures differential pressure, liquid level or gauge pressure
and transmits a proportional 4 to 20mA signal. The trans-
mitter utilizes a unique micromachined capacitance silicon
sensor with state-of-the-art microprocessor technology to
provide exceptional performance and functionality. 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 DP models covering 0.32kPa {3.2mbar}
range to 500kPa {5bar} high differential 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 adjustment.
2. Minimum environmental influence
The “Advanced Floating Cell” design which protects the
pressure sensor against changes in temperature, static
pressure, and overpressure substantially reduces total
measurement error in actual field applications.
3. Fuji/HART^® bilingual communications protocol and
FOUNDATION™ fieldbus and Profibus™ compatibil-
ity
FCX–A2 series transmitter offers bilingual communi-
cations to speak both Fuji proprietary protocol and
HART^®. Any HART^® compatible devices can commu-
nicate with FCX–A2. Further, by upgrading electron-
ics FOUNDATION™ 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
terminal 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. Programmable output Linearization Function
In addition to Linear and Square Root, output signal
can be freely programmable.
(Up to 14 compensated points at approximation.)
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.
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.

– The maximum span of each sensor can be converted
to different units using factors as below.

Overrange limit: To maximum static pressure limit
Output signal: 4 to 20mA DC (linear or square root) with
digital signal superimposed on the 4 to
20mA signal
Power supply: Transmitter operates on 10.5V to 45V DC
at transmitter terminals.
10.5V to 32V DC for the units with optional
arrester.
