A pressure sensor is an electronic device designed to measure and monitor pressure levels in various areas. These sensors use various technologies such as piezoresistive, capacitive or piezoelectric to convert pressure into an electrical signal. The sensor consists of a sensing element that deforms under pressure and produces a proportional output. This output signal can be in the form of voltage, current or digital data depending on the sensor type and interface.

Pressure sensors are widely used in industries such as automotive, aerospace, medical, HVAC (heating, ventilation and air conditioning) and process control systems. They play an important role in ensuring the efficiency, safety and reliability of many systems.

 

For example, in the automotive industry, pressure sensors are needed to measure tire pressure, engine oil pressure, and fuel system pressure. In medical devices, it is used for blood pressure monitoring, respiratory therapy, and intravenous infusion control.
