What is a Pressure Sensor?

A pressure sensor is a device or instrument which is able to measure the pressure in gases or liquids. A pressure sensor consists of a pressure-sensitive element which can determine the pressure being applied and components to convert the information into an output signal. A pressure sensor will generate a signal based on the measurement of the pressure applied.

Pressure Transducers, Transmitters and Switches

There are different types of pressure sensors. Pressure transducers – also called Pressure Transmitters and Pressure Switches.

Pressure Switches – A pressure switch will not indicate actual pressure; they are designed to make or break a contact when the desired pressure range is reached. Pressure switches are well known for their quick response times. They are dependable and offer long working life. Pressure switches are often small in size and they are lower cost than other pressure sensing devices.

Pressure transducers – Pressure Transducers give feedback on the actual system pressure through an analogue or digital output. Pressure Transducers are generally more expensive than pressure switches but are more robust and stronger. Pressure transducers are able to withstand harsh environmental conditions and are resistant to water and dirt. Pressure transducers are suitable for more industrial applications and vehicle applications offering excellent accuracy and high strength.
