FCX – C SERIES
FLOW TRANSMITTER
DATA SHEET
FHN
The FCX–C flow transmitter accurately measures
differential pressure generated by a primary element, and
transmits 4 to 20mA signal proportional to flow. 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 a range of 50% to 100% of flow) for
all calibrated spans is the standard feature for all models
covering 0.6kPa{6mbar} draft range to 2000kPa{20bar}
high differential. Fuji's micro-capacitance silicon sensor
assures this feature.
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 140bar).
3. Upgradable electronics
A small plug-in communication module (to be ordered
separately) can upgrade your FHN flow transmitters to
have remote communication functions. A Hand Held
Communicator (Model FXW, consult Data sheet No.
EDS8-47) can remotely display or reconfigure process
values as well as all transmitter configuration parameters
at any point on the loop without affecting the transmitter
signal.
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 1 -digits LCD meter
