Cells sensitive element: Silicon chip Micro capacitance based technology


  • Decrease of hysteresis and mechanical fatigue problems on the sensitive element
  • Very high zero stability and long term reliability

Optional fuctionality:

  • Digital indicator
  • burnout current
  • maintenance
  • communication

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).


Hand held communicators

Our hand held communicator (FXW) 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

coating for prevention of hydrogen diffusion in the measurement cell (hydrogen sulphide): Gold and Ceramic

For certain configurations, the process fluids generate hydrogen atoms that may be diffused through the metal diaphragm. The contamination of the oil associated with this diffusion degrades the transmitter’s measurement accuracy and life time. Thanks to our gold and ceramic double-coating diaphragm, the hydrogen’s permeation is stopped.
In this configuration, the transmitters may be used in sulphur reduction installations, hydrogen production units, oil refineries and putrefaction mud treatment works.

anti corrosive and chemical attacks: Hastelloy C, Tantalum, Monel

Different materials and coatings are available for the pressure transmitter diaphragms to guarantee the longevity and reliability of your measurements.

Transmitter measurement diaphragm materials and their applications:

Gold & ceramic coating: Sulphur reduction installations, hydrogen production units, oil refineries and putrefaction mud treatment works, ionised gas (hydrogen sulphide)

Tantalum: Hydrochloric acid, sulphuric acid, nitric acid, aqua regia

Titanium: Sodium chloride, sulphate compound

Hastelloy-C: Organic acid, inorganic acid, alkaline type

Monel: Alkaline type, fluorinated acid

Zirconium: Hydrochloric acid, caustic soda, whitening agent
