Fuji Electric FCX-AII V5 micro capacitance based technology

Micro capacitance silicon sensor
Based on our extensive silicon chip manufacturing experience,Fuji Electric developed the unique micro capacitancesilicon 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...

Fuji Electric FCX-AII V5 Optional functionality

Digital indicator
The FCX-All V5 transmitter may be equipped with an analog 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 push buttons. The indicator enables the measurement in physical units and the local configuration of the transmitter.

Main settings:
- Zero/Span calibration without reference pressure service
- Linear or square root signal
- Damping
- Digital indicator configuration
- 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 stored 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).

Fuji Electric FCX-AII V5 Communication

Hand held communicators
Fuji Electric hand held communicator is a very useful configuration tool for the FCX-AII V5 transmitter. As a menu driven device, the HHC can be used to remotely display and configure transmitter parameters (zero, span, burnout, output signal, auto diagnostic, type of output signal, damping, current generation, tag, model number of the transmitter etc.) Using the Hart® communication protocol, the FCX-AII V5 transmitter can also be configured by any Hart® protocol compatible hand held communicator.



Communication software Hart® Explorer
The FCX-AII V5 pressure transmitter can also be configured using Hart® communication based software “Hart® Explorer” connected to your Laptop or PC. Configuration of the above parameters is possible and the settings can also be saved for future reference. It’s also possible to measure and record process values. The interface between the PC and the transmitter is performed by a mini modem USB / Hart® to guarantee the communication between the PC and the 4 to 20 mA loop of the transmitter.

Transmitter measurement diaphragm materials

Hydrogen is the smallest atom element. So, it can penetrate the metal process diaphragms of pressure transmitters, reducing measurement accuracy and a transmitter's lifetime.



Since Fuji Electric's special seal diaphragm double coated with gold and ceramic significantly suppresses the hydrogen permeation, the transmitter is suitable for desulfurization facilities and hydrogen production units for petroleum refining.

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.
Minimum environmental influence
The “Advance Floating Cell” design which protects the pressure sensor against changes in temperature, and overpressure substantially reduces total measurement error in actual field applications.
Fuji/HART® bilingual communications protocol
FCX–AIII series transmitter offers bilingual communications to speak both Fuji proprietary protocol and HART®. Any HART® compatible devices can communicate with FCX–AIII.
Application flexibility
Various options that render the FCX–AIII suitable for almost any process applications include:
– Full range of hazardous area approvals
– Built-in RFI filter and lightning arrester
– 5-digit LCD meter with engineering unit
