FCO432 Users Guide Issue 1
Introduction
General Description
The FCO432 is a fully configurable, industrial differential pressure transmitter. The configuration must
be carried out using either the FCS541 Utility software and cable, or the optional built in keypad. The
pressure cell is based on the unique Furness Controls capacitive sensor of proven reliability. A
microcontroller is used to control all functions of stability, such as temperature correction and display
damping. The output can be scaled as a linear or rooted function to facilitate the use of Pitot Static
Tubes or other primary flow elements. The FCO432 is suitable for industrial applications of control,
measurement and monitoring.
Features include:
Optional large character LCD display or an OLED display
Linear or rooted (Square root by default) output.
10:1 range adjustment using the Model 400 series software or optional keypad.
Optional Configurations:
2-Wire 4 to 20mA Current output
4-Wire Isolated 4 to 20mA Current output
4-Wire Isolated Voltage output
0 to 1V, 0 to 2V, 0 to 5V, 0 to 10V,
1V,
2V,
5V or
10V
Remote Zeroing Function
Zero the FCO432 with an externally fitted button, or suitable electronic circuitry.
Auto Zeroing Function
Adjustable delay between 0.0 and 24.0 hours with 0.1 hour resolution. Available to instruments
with the necessary hardware option fitted.
Dual Relay Trip Outputs
Relays can be configured to trip at pre-defined levels, or within a pre-defined pressure band.
Available to instruments with the necessary hardware option fitted.
Typical applications include:
Combustion pressure measurement and control of industrial furnaces
Air pressure measurement and control of dryers, kilns and ovens
Air flow measurement in conjunction with pitot static tubes, orifice plates or venturi
Enclosure
The instrument is housed in an IP54 rated ABS enclosure.
Pneumatic connections (fitted as standard) are for Ø4mmID push on tubing.
Optional pneumatic connections are:
⅛” BSPP Female threaded adaptor
¼
” BSPP Female threaded adaptor
