Fuji
DP Pressure Transmitters
  Overview
1. High accuracy
0.2% accuracy for all calibrated spans is a standard feature
for all AP models covering 1.6kPa {0.016bar} range
to 3000kPa {30bar} high pressure range. 0.1% accuracy
is available as option. Fuji’s micro-capacitance silicon
sensor assures this accuracy for all suppressed calibration
ranges without additional adjustment.
2. Minimum environmental influence
The “Advanced Floating Cell” design which protects the
pressure sensor against changes in temperature, and
overpressure substantially reduces total measurement
error in actual field applications.
3. Fuji/HART® bilingual communications protocol and
FOUNDATION™ fieldbus and Profibus™ compatibility
FCX–A2 series transmitter offers bilingual communications
to speak both Fuji proprietary protocol and HART®.
Any HART® compatible devices can communicate with
FCX–A2. Further, by upgrading electronics FOUNDATION
™ fieldbus and Profibus™ are also available.
4. Application flexibility
Various options that render the FCX – A2 suitable for
almost any process applications include:
– Analog indicator at either the electronics side or terminal
side
– Full range of hazardous area approvals
– Built-in RFI filter and lightning arrester
– 5-digit LCD meter with engineering unit
– Stainless steel electronics housing
– Wide selection of materials
5. Burnout current flexibility (Under Scale: 3.2 to 3.8mA,
Over Scale: 20.8 to 21.6mA)
Burnout signal level is adjustable using Model FXW Hand
Held Communicator (HHC) to comply with NAMUR NE43.
6. 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
     
Technical Specification  
  • Service: Liquid, gas, or vapour
    Span, range, and overrange limit:
    Remark: To minimize environmental influence, span should be greater
    than 1/40 of the max. span in most applications.
    – The maximum span of each sensor can be converted to
    different units using factors as below.
    1MPa abs=103kPa abs=10bar abs=10.19716kgf/cm2 abs
    =145.0377psi abs
    1kPa abs =10mbar abs=101.9716mmH2O abs
    =4.01463inH2O abs=7.50062mmHg abs
    Output signal: 4 to 20mA DC with digital signal superimposed
    on the 4 to 20mA signal.
    Power supply: Transmitter operates on 10.5V to 45V DC
    at transmitter terminals.
    10.5V to 32V DC for the units with optional
    arresterZero/span adjustment:
    Zero and span are adjustable from the
    HHC(1). Zero and span are also adjustable
    externally from the adjustment screw
    (span adjustment is not available with 9th
    digit code “L, P, Q, S”).
    Damping: Adjustable from HHC or local adjustment
    unit with LCD display.
    The time constant is adjustable between
    0.12 to 32 seconds.
    Zero elevation/suppression:
    Zero can be elevated within the specified
    range limit of each sensor model.
    Normal/reverse action:
    Selectable from HHC(1).
    Indication: Analog indicator or 5-digit LCD meter, as
    specified.
    Burnout direction: Selectable from HHC(1)
    If self-diagnostic detect transmitter failure,
    the analog signal will be driven to either
    “Output Hold”, “Output Overscale”
    or “Output Underscale” modes.
    “Output Hold”:
    Output signal is hold as the value just before
    failure happens.
    “Output Overscale”:
    Adjustable within the range 20.8mA to
    21.6mA from HHC(
