Pressure Transmitter

Pressure Transmitter


Pressure transmitter is a device used to measure the pressure of liquids and gases. Similar to other sensors, the pressure transmitter converts pressure into electrical signal output when it works. Pressure sensors are used extensively in many monitoring and control applications. In addition to direct pressure measurement, pressure sensors can also be used to indirectly measure other quantities, such as liquid/gas flow, velocity, water surface, or altitude.


Pressure transmitter is a mechanical device that converts the expansion force of a liquid or gas sample into an electrical output. The device converts the pressure into an electrical signal by means of a transducer. This type of sensor, also known as a pressure transducer, usually consists of a pressure-sensitive surface area made of steel, silicon, or other materials, depending on the composition of the analyte. Behind these surfaces are electronic components capable of converting the force applied to the pressure sensor by the sample into an electrical signal.
