Absolute Pressure Sensors and Absolute Pressure Transducers

This section illustrates our range of absolute pressure sensors that can be used to measure pressure referenced to an absolute vacuum.

The absolute pressure ranges covered are 0-500mbar up to 0-700bar on analogue output versions and 0-50mbar up to 0-1000bar on digital output versions.

Output signal options on our absolute pressure sensors include mV/V, 0.5-4.5Vdc, 0-5Vdc, 0-10Vdc and 4-20mA, with customised outputs available on request.

All absolute pressure sensor models can be supplied with digital displays and indicators, signal digitisers, telemetry systems, data loggers and acquisition equipment from our range of transducer instrumentation.  Calibration traceable to UKAS standards is available on all absolute pressure sensors and systems.

Absolute Pressure Explained

Absolute pressure is measured relative to absolute zero pressure as would be found in an absolute vacuum.   In pressure transducers, a high vacuum sealed behind the sensing diaphragm provides this absolute zero reference.
