What is a pressure sensor and the reasons why pressure sensors are prone to failure 1

A pressure sensor is a device that converts the pressure of a liquid or gas into an electrical signal output. They are usually composed of sensitive components and signal conversion processing circuits. Sensitive components (such as piezoelectric materials, resistance strain gauges, capacitor membranes, etc.) diode  undergo changes in their physical properties when subjected to external pressure, which in turn causes changes in their electrical characteristics (such as resistance, capacitance, or voltage). These changes are converted and amplified, and ultimately output as electrical signals for easy reading, display, or control.diode

The working principle of pressure sensors depends on their type. The most common types include mechanical pressure sensors, piezoelectric pressure sensors, and piezoresistive pressure sensors.diode  Mechanical pressure sensors use mechanical deformation to measure pressure; Piezoelectric sensors detect pressure by measuring the changes in charge generated by certain materials when subjected to force; And piezoresistive sensors work by detecting the principle of material resistance changing with pressure.diode

Pressure sensors have a wide range of applications, including industrial automation, automotive engineering, medical equipment, environmental monitoring, and aerospace. The pressure range that sensors can detect ranges from a few pascals (micro pressure) to several kilomegapascals (ultra-high pressure).
