Pressure sensors

A pressure sensor is a device whose physical parameters change depending on the pressure of the measured medium (liquid, gas, steam). In the sensors, the pressure of the measured medium is converted into a unified pneumatic, electrical signals or a digital code.

The pressure sensor consists of a primary pressure converter, which includes a pressure sensor element, a secondary signal processing circuit, various components of the body parts design, including hermetically connector to the object and protecting it from external influences, and information signal output device. The main differences between some devices are the measurement limits, dynamic and frequency ranges, the accuracy of pressure registration, permissible operating conditions, weight and size characteristics, which depend on the principle of converting pressure into electrical signal: strain gauge, piezoresistive, capacitive, inductive, resonant, ionization, piezoelectric and others.

Absolute and relative pressure sensors have standard voltage outputs or current outputs of 0-5mA ; 4-20 mA
