DIFFERENTIAL PRESSURE (FLOW) TRANSMITTER
FHC...4
DATA SHEET
The FCX–A2e differential pressure (flow) transmitter accurately measures differential pressure, liquid level, gauge
pressure or flow rate and transmits a proportional 4 to 20mA
signal. The transmitter utilizes a unique micromachined
capacitance silicon sensor with state-of-the-art microprocessor technology to provide exceptional performance and
functionality.
FEATURES
1. High accuracy ±0.1%
0.1% accuracy is a standard feature.
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
FCX–A2e series transmitter offers bilingual communications 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
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
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.
