EDSX5-86D Datasheet, PDF (1/6 Pages) Fuji Electric – PRESSURE TRANSMITTER

DATA SHEET
PRESSURE TRANSMITTER
FHG...4
The FCX – A2e 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.
FEATURES
1. High accuracy ±0.1%
0.1% accuracy is a standard feature. Fuji’s micro-capaci-
tance silicon sensor assures this accuracy for all elevated
or suppressed calibration ranges without additional ad-
justment.
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. Fuji/HART^® bilingual communications protocol
FCX–A2e series transmitter offers bilingual communica-
tions to speak both Fuji proprietary protocol and HART^®.
Any HART^® compatible devices can communicate with
FCX–A2e.
4. Application flexibility
Various options that render the FCX – A2e 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
– 5-digit LCD meter with engineering unit
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.
