Pressure Sensor

Pressure sensors contain a pressure transducer that converts a measured pressure into an electrical signal. There are four types of commonly used pressure sensors – Gauge, Sealed Gauge, Differential and Absolute.

Gauge
Gauge pressure sensors take atmospheric pressure as the reference point. Generally, a gauge pressure sensor has a vented tube connecting to the atmosphere making it the reference pressure point in any pressure measurement.

Sealed Gauge
Sealed Gauge pressure sensors use a pre-determined pressure as the reference point. Sealed gauge pressure sensors are used in high-pressure measurements where atmospheric pressure changes have a very minor impact on the accuracy of the sensor.

Absolute
Absolute pressure sensors measure pressure that is referenced to a perfect vacuum.

Differential
Differential pressure sensors measure the difference in pressure between two points. These gauges have two inlet ports (a high pressure port and a low pressure port) and each port is connected to the media whose differential pressure needs to be measured.
