Pressure Sensor

Definition - What does Pressure Sensor mean?

A pressure sensor, as the name suggests, is a device that senses and measures pressure (usually of gases or liquids). The pressure sensor in electronic circuits is in the form of an integrated circuit that acts as a transducer, that is, it replicates (in the form of an electrical signal) the signal it receives as a function of imposed pressure.

A pressure sensor is also known as a pressure transducer, pressure transmitter, pressure sender, pressure indicator, piezometer and manometer.

Techopedia explains Pressure Sensor

Thousands of everyday appliances utilize pressure sensors, although they are not used directly in all these devices and are often indirectly used in the measurement of fluid/gas flow, speed, water level and altitude. Pressure sensors are among the most widely used electronic sensors and are manufactured by more than 300 companies worldwide. There are at least 50 different technological methods, all varying in design, performance rating, efficiency, cost and output method. Advanced pressure sensors include the dynamic sensor category, where very high speed changes in pressure are measured, and they are manufactured from non-conventional materials such as quartz. Some pressure sensors, such as those used in industry, act as a binary switch.
