What are pressure sensors?

A pressure sensor is an electronic detection device capable of measuring the amount of pressure applied to gases and liquids. These sensors possess a pressure-sensitive element that allows them to detect the amount of applied pressure and translates the information into a readable output signal. 

Types of pressure sensors

Pressure sensors are available in different types but can be chiefly categorised into the following two varieties: 

Pressure switches

These types of pressure sensors are designed to connect or disconnect direct contact as soon as the defined pressure range has been reached. This is why they are called ‘switches’ and they cannot measure the actual amount of applied pressure.

Pressure transducers

These types of pressure sensors are used to generate feedback on the actual amount of pressure by measuring it and presenting the reading in a digital or analogue output.

Importance of pressure sensors

Pressure sensors are important types of sensors and are widely used across a multitude of industrial and non-industrial domains. For instance, they are critical for many automotive manufacturing operations, making them integral to the automotive industry. Similarly, they are exceptionally ideal for industrial processes and automated building systems. Pressure sensors have extensive applications in life-saving medical appliances and consumer-based industries.
