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

A pressure sensor is a device that converts the pressure of liquids or gases into electrical signals. It typically consists of a sensitive element and a signal conversion and processing circuit. When subjected to external pressure, the sensitive element (such as piezoelectric materials, resistance strain gauges, capacitive diaphragms, etc.) undergoes changes in its physical properties, which in turn alter its electrical characteristics (such as resistance, capacitance, or voltage). These changes are converted and amplified, ultimately outputting as an electrical signal for reading, display, or control purposes. 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. Mechanical pressure sensors measure pressure by utilizing mechanical deformation; piezoelectric sensors detect pressure by measuring the electrical charge changes generated in certain materials when subjected to force; while piezoresistive sensors operate based on the principle of detecting changes in material resistance with pressure.diode

Pressure sensors have a wide range of applications, including industrial automation, automotive engineering, medical devices, environmental monitoring, and aerospace. These sensors can detect pressures ranging from a few pascals (micro-pressure) to several gigapascals (ultra-high pressure), and the appropriate ADP121-AUJZ28R7 pressure sensor is selected based on different application fields.diode
