FCX – C SERIES
DIFFERENTIAL PRESSURE TRANSMITTER
DATA SHEET
FHK, FKK
The FCX –C differential pressure transmitter accurately
measures differential pressure, liquid level or gauge pressure
and transmits proportional 4 to 20mA signal. The transmitter
utilizes the unique micromachined capacitive silicon sensor
with state-of-the-art microprocessor technology to provide
exceptional performance and functionality.
FEATURES
1. High accuracy
0.1% accuracy for all calibrated spans is the standard
feature covering 0.6kPa {60mbar} draft range to 2000kPa
{20bar} high differential. Fuji's micro-capacitance silicon
sensor assures this feature for all elevated or suppressed
calibration ranges without additional adjustment.
2. Minimum inventory
Electronics unit, communication module, local indicators
and electronics housing are interchangeable among all
FCX –C models. Process cover including bolts and nuts
are common for all DP and flow transmitters, rating 3.2
and 14MPa (32 and 140 bar).
3. Replaceable Communication Module
Fuji micro-electronics manufacturing technology offers
replaceable communication module that makes FCX-A/
C transmitter very unique design. In case of change in
communication protocol all that needs to be done is just
replace the module and the transmitter gets upgraded
to the new version.
4. Fuji/HART bilingual communication module
The communication module is "bilingual" to speak both
Fuji proprietary protocol and HART. Any HART compatible
devices can communicate with FCX-A/C series transmitters.
5. Application flexibility
Example features that render the FCX –C suitable for
almost any process applications includes.
– Analog indicator at either the electronics side or
terminal side
– Full range of hazardous location approvals
– Built-in RFI filter and lightning arrester
– 4 12 -digits LCD meter
