EDSX5-92H Datasheet, PDF (1/8 Pages) Fuji Electric – PRESSURE TRANSMITTER

PRESSURE TRANSMITTER
DATA SHEET
FKG...5
The FCX – AIII pressure transmitter accurately measures
gauge pressure and transmits a proportional 4 to 20mA
signal.
The transmitter utilizes a unique micromachined capacitance
silicon sensor with state-of-the-art microprocessor technol-
ogy to provide exceptional performance and functionality.
FEATURES
1. High accuracy up to ±0.04%
0.065% accuracy as standard, 0.04% accuracy as option.
Fuji’s micro-capacitance silicon sensor assures this ac-
curacy for all elevated or suppressed calibration ranges
without additional adjustment.
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–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 al-
most 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
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.
