EDSX7-62K Datasheet, PDF (1/12 Pages) Fuji Electric – SMALL FLANGE LEVEL TRANSMITTER

SMALL FLANGE LEVEL TRANSMITTER
DATA SHEET
FKY...4
The FCX–A2 small flange level transmitter accurately mea-
sures liquid level and transmits a proportional 4 to 20mA
signal. The transmitter utilizes a unique micromachined
capacitance silicon sensor with state-of-the-art microproces-
sor technology to provide exceptional performance and func-
tionality.
FEATURES
1. Directly connectable to 1-^1/2 in. and 2 in. flanges
The transmitter is connectable to 1-^1/2 in. and 2 in. pipes
without a reducer.
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 communica-
tions to speak both Fuji proprietary protocol and HART^®.
Any HART^® compatible devices can communicate with
FCX–A2.
Further, by upgrading electronics 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 ter-
minal 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 service.
5. Programmable output Linearization Function
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 cali-
bration 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.

Silicone fill sensor: See Fig.1
Fluorinated fill sensor: 66kPa abs (500mmHg abs) at
temperature below 60 °C.
– The maximum span of each sensor can be converted to
different units using factors as below.
1MPa=10³kPa=10bar=10.19716kgf/cm²=145.0377psi
1kPa=10mbar=101.9716mmH2O=4.01463inH2O
Overrange limit: To maximum static pressure limit
Output signal: 4 to 20mA DC with digital signal superim-
posed 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 op-
tional arrester.
