What Does Pressure Sensor Mean?

A pressure sensor is a device used to measure and record the pressure applied by liquids or gases. Most sensors work by converting pressure into an analog or digital signal that is then sent to a gauge to display the reading. Some pressure sensors can also be used to indirectly measure other parameters, such as fluid level, flow speed and altitude. Pressure sensors are used in various industrial equipment, such as tanks, vessels and pipelines to continuously measure stress readings.

Pressure sensors are also known as pressure transducers, piezometers and pressure indicators.

Corrosionpedia Explains Pressure Sensor

The most common type of pressure sensor is known as a strain-based gauge transducer. In these devices, applied pressures physically deform a strain gauge, which alters its electrical resistance. This resistance proportionally affects the electrical signal sent to the gauge.

Pressure sensors are classified mainly by the type of pressure they measure. Some of the most common types of sensors include:

  • Absolute pressure sensors
  • Gauge pressure sensors
  • Vacuum pressure sensors
  • Differential pressure sensors
