FCO432 Differential Pressure Transmitter

The versatile FCO432 is a cost-effective industrial differential pressure transmitter suitable for a variety of clean environment applications. There are 11 models available, each with different pressure ranges, as well as a selection of configurable options to create the ideal instrument.

The FCO432 provides very high precision at the lowest pressures.
The 11 models start with the ±50Pa measurement range and graduate through to -1bar to +10bar,
each with an accuracy of <0.25% of reading. The pressure cell is based on the sensor's proven reliability.
A microcontroller is used to control all functions of stability, such as temperature correction and display damping.

Available with standard 2-wire 4-20mA and 4-wire isolated 4-20mA current output, as well as voltage options,
the FCO432 can fit into a variety of industrial set-ups.
Additional flexibility is provided by USB, RS232, and RS485 communication options.

The differential pressure transmitter comes with two display options.
There is the choice between a large character, low power LCD display, which is fully compatible with 4-20mA options,
or a high brightness, illuminated OLED display (this requires a separate 24V power supply),
enabling the device to be used for a multitude of applications. Alternatively, the device can be used blind, without a display.

There are two ways in which to configure the FCO432. A membrane keypad is available as an optional extra for easy,
on-device field configuration. Otherwise, the configuration can be carried out using the provided FCS541 utility software
and internal Micro-USB connection.

By using one of these methods, the transmitter can be configured in a multitude of ways.
The output is scalable as linear to differential pressure, or as a square-root function to facilitate
the use of Pitot Static Tubes or other primary flow elements.

The two independent trip level relays can be set to indicate an alarm signal at either predefined levels,
or within a predefined pressure band.
