It is a device utilized for the pressure measurement of gases or liquids. Pressure is an expression of the force necessary to stop a fluid from expanding.
A pressure sensor acts like a transducer as it will generate a signal as a function of the pressure imposed.
These devices can vary drastically in technology, design, performance, application, and cost.
They can be alternately termed as pressure transducers or even something such as manometers.
Pressure sensors are used for control and monitoring in thousands of everyday applications. Pressure sensors can also be used to indirectly measure other variables such as fluid/gas flow, speed, water level, and altitude.
