Background

A pressure sensor is a device or apparatus that senses a pressure signal and converts the pressure signal into a usable output electrical signal according to a certain rule. A pressure sensor is usually composed of a pressure sensitive element and a signal processing unit. Pressure sensors can be classified into gauge pressure sensors, differential pressure sensors, and absolute pressure sensors according to different types of test pressures. The pressure sensor is the most common sensor in industrial practice, is widely applied to various industrial automatic control environments, and relates to a plurality of industries such as water conservancy and hydropower, railway traffic, intelligent buildings, production automatic control, aerospace, military industry, petrochemical industry, oil wells, electric power, ships, machine tools, pipelines and the like.

The existing pressure sensor has a complex structure, so that the manufacturing cost is high, and the interfaces cannot be compatible.

To solve the above problem, we propose a pressure sensor.
