Pressure sensor is a device or device that can sense pressure signals and convert the pressure signals into usable output electrical signals according to certain rules.

The pressure sensor is usually composed of a pressure sensitive element and a signal processing unit. According to different test pressure types, pressure sensors can be divided into gauge pressure sensors, differential pressure sensors and absolute pressure sensors.

Pressure sensor is the most commonly used sensor in industrial practice. It is widely used in various industrial automation environments, involving water conservancy and hydropower, railway transportation, intelligent buildings, production automation, aerospace, military, petrochemical, oil well, electricity, ships, machine tools , Pipelines and many other industries.
