EDSX6-116K Datasheet, PDF (1/12 Pages) Fuji Electric – SMALL FLANGE REMOTE SEAL TYPE DIFFERENTIAL PRESSURE TRANSMITTER

SMALL FLANGE REMOTE SEAL TYPE
DIFFERENTIAL PRESSURE TRANSMITTER
DATA SHEET
FKX...4
The FCX–A2 small flange remote seal type differential
pressure transmitter accurately measures differential
pressure, liquid level or 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 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. Directly connectable to 1-^1/2 in and 2in flanges
The transmitter is connectable to 1-^1/2 in and 2in pipes
without a reducer.
2. Flow measurement without impulse piping
1/2 _{in and} 3/4 _{in flange size is also available. This differ-}
ential pressure transmitter allows connection to ^1/2 in
and ^3/4 in flanges of a general size for the orifice tap,
which eliminates the need of using a impulse piping.
Problems with the impulse piping, such as clogging, leaks
or corrosion can be solved. In addition, the following
process connection is also available.
Screw connection ^1/2-14NPT, ^3/4-14NPT, Rc ^1/2, Rc ^3/4
3. 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.
4. 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.
5. 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
6. Programmable output Linearization Function
In addition to Linear and Square Root, output signal can
be freely programmable.
(Up to 14 compensated points at approximation.)
7. 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.
9. 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.
