Fuji Electric pressure transmitters FCX-AII series


FCX-AII transmitters offer measuring ranges from 10 mmCW and 500 bar and are available for differential, gauge and absolute pressure. For specific apllications like petrochimistry, our differential pressure transmitters can be used for static pressure up to 1035 bar.

• ACCURACY : Standard :     ± 0.065% of calibrated span
                          Optional :      ± 0.04%
of calibrated span
• Long term STABILITY :           ± 0.1% of max. span / 10 yers                                                                                                                                                                                   

Micro capacitance silicon sensor

Based on our extensive silicon chip manufacturing experience,
Fuji Electric developed the unique micro capacitance
silicon sensor as the centrepiece of FCX-AII transmitters. To minimise static pressure, overpressure temperature effects, It is assembled floating in the measuring cell neck.
As a measuring diaphragm material, the sensor uses as a single crystal silicon that has minimal hysteresis and fatigue which improves the transmitter’s characteristics improving long term stability of zero and reliability.

Thanks to 0,065% standard accuracy (up to 0,04% at option), a great rangeability of 100 :1 and the various materials available for wetted parts (Tantalum, Monel, Hastelloy-C or PVDF) our transmitters can be used in various applications in industry fields such as petrochemistry, chemistry, energy, iron industry, food industry and water treatment.

Measuring cell

The differential pressure is applied on the silicone sensor and changes the two capacitance values of the sensor. It is assembled floating in the measuring cell neck and improves the static pressure and temperature characteristics...

Digital Indicator

The FCX-AII V5 transmitter can be fitted with an optional local analogue, or digital indicator. The digital indicator is based on LCD technology and shows the information on 2 lines each of 6 digits and also includes 3 switches. The indicator can be used to show the output signal in engineering units, as a percentage or as a current in mA (this is useful for flow indication on a differential pressure transmitter).

Features :

  • Zero/Span calibration without reference pressure
  • Linear or square root signal
  • Damping
  • Configuration on the digital indicator
  • Zero/Span calibration
  • Self diagnosis
  • Output circuit calibration
  • Direction and value of burnout...

Burnout current :
In conformance with the recommendations of NAMUR NE 43, the output of the transmitter can be driven to a specific value should the transmitter experience an internal failure. The standard output signal limits are 3,2 to 22,5 mA. In case of a transmitter failure, the burnout direction can be down scaled (3,2 to 4 mA) or up scaled (20 to 22,5 mA), being programmable.
Maintenance functions :
The calibration parameters are saved in the transmitter. At any time it is possible to come back to the factory calibration of the transmitter. Min and max temperatures are stocked in the transmitter memory. It is always possible to visualize the values in a specific menu on the screen of the hand held communicator.
All the adjustment functions of the transmitter can be locked by a password (the external adjusting screw is also locked).
