Pressure sensors are used in many industries to monitor pressure levels of the machinery being used. Measuring level, altitude, flow and the speed of gases and liquids are some of the functions offered by pressure sensors. Pressure sensors come in various types so you can choose one according to your needs and budget. Depending on the industry in which they are used, the design and technology behind the pressure sensor may vary.
Pressure sensors usually come in 5 different types: Absolute, Gauge, Differential, Sealed and Vacuum. In order to differentiate between these sensors, you need to be aware of what and how they measure pressure readings.
Absolute pressure sensor: These pressure sensors are used to gauge pressures like atmospheric pressure. They measure pressure starting from 0 PSI.
Gauge pressure sensor: These pressure sensors are commonly used to measure the pressure in tyres relative to absolute pressure.
Differential pressure sensor: These pressure systems are commonly used in industry. They are used to measure the difference in pressure between two or more pressure points.
Sealed and vacuum pressure sensors: Sealed pressure sensors are used to gauge pressure related to sea-level pressure while vacuum pressure sensors measure pressure that is less than 0 PSI.
