Answer: A pressure sensor is a sensor that converts pressure signals into electrical signals. It is mainly divided into two types: static and dynamic pressure sensors. High-frequency pressure sensors are mainly piezoelectric pressure sensors, while low-frequency static pressure sensors are mainly piezoresistive silicon and strain gauge pressure sensors. Dynamic pressure sensors are mainly used in the fields of explosion physics, wind tunnel testing, and free-field pressure measurement; static pressure sensors are mainly used in the fields of safety control, production process control, etc.
