PRESSURETRANSMITTER(DIRECTMOUNTTYPE)

DATA SHEET

The FCX-AII pressure transmitter accurately measures gauge pressure and transmits proportional 4 to 20 mA 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%

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 inventory and design

Electronics unit, local indicators and electronics housing are

interchageable among all FCX-AII transmitters.

3.Minimumenvironmentalinuence

The “Advance Floating Cell” design which protects the pres-

sure sensor against changes in temperature, and overpressure substantially reduces total measurement error in actual

eld applications.

4. Fuji/HART

FCX-AII series transmitter offers bilingual communications to

speak both Fuji proprietary protocol and HART

Any HART

AII.

5.Applicationexibility

Various options that render the FCX-AII suitable for almost

any process applications include:

– Analog indicator at either the electronics side or terminal

– Full range of hazardous area approvals

– Built-in RFI lter and lightning arrester

– 5 digit LCD meter with engineering unit – Stainless steel electronics housing – Wide selection of materials

6. Programmable output Linearization Function

Output signal can be freely programmable. (Up to 14 compensated points at approximation)

7.Burnoutcurrentexibility(Under Scale: 3.2 to 4.0 mA, OverScale:20.0to22.5mA)

Burnout signal level is adjustable using Model FXW or Hand

Held Communicator (HHC) to comply with NAMUR NE43.

8. 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.
