Description

technical field [0001] The invention relates to the technical field of sensor detection, in particular to a detection device for a pressure sensor. Background technique [0002] A 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. Pressure sensors are usually composed of pressure sensitive elements and signal processing units. According to different test pressure types, Pressure sensors can be divided into gauge pressure sensors, differential pressure sensors and absolute pressure sensors. Pressure sensors are the most commonly used sensors in industrial practice. They are widely used in various industrial self-control environments. Some pressure sensors have particularly high environmental requirements. In particular, the requirements for sealing and high temperature resistance are extremely strict. If the sealing is not good, water will enter the inside of ...
