Common pressure sensors include resistance strain gauge pressure sensor, semiconductor strain gauge pressure sensor, positive pressure sensor, inductive pressure sensor, capacitive pressure sensor, resonant pressure sensor, capacitive acceleration sensor, optical fiber pressure sensor and so on. Piezoresistive pressure sensor is the most widely used pressure sensor, which has the characteristics of low price, high precision and good linearity.

Pressure sensor is the most widely used sensor, which is used in various industrial automatic control environments, involving water conservancy and hydropower, railway transportation, intelligent building, production automatic control, aerospace, military industry, petrochemical, oil wells, electric power, ships, machine tools, pipelines and many other industries.
