Differential Pressure Transmitter (FCO432)

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

  • Multiple output functions: linear, square-root, custom linearisation

Ultra Low Pressure Measurement

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 <0.25% of reading. 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.

    Fully Configurable with Multiple Functions

    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, 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 FCO432 can be zeroed in two ways to guarantee high levels of accuracy. An externally fitted button or suitable electronic circuitry can remotely zero the device. Or there is the option to use the auto-zeroing function with an adjustable delay between 0.0 and 24.0 hours, with a 0.1 hour resolution.

    LCD or OLED Display 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 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.

      Typical Use Cases

      Accurate measurement and control is the key to automation across the manufacturing sector. Our pressure transmitters are used to monitor industrial processes, environmental conditions and safety parameters, ensuring your critical processes run smoothly. The FCO432 is suitable for industrial applications of control, measurement and monitoring, including:
