Description

Technical Field

[0001] The utility model relates to the technical field of pressure sensors, and more particularly to a pressure sensor protection mechanism. Background Art

[0002] A pressure sensor is a device or apparatus that can sense pressure signals and convert them into usable output electrical signals according to certain rules. A pressure sensor usually consists of a pressure-sensitive element, a device that converts the force or motion generated by the pressure-sensitive element into electrical parameters, and a device that displays or records the electrical parameters. According to different test pressure types, pressure sensors can be divided into gauge pressure sensors, differential pressure sensors, and absolute pressure sensors. They are widely used in various industrial automation environments, involving water conservancy and hydropower, railway transportation, intelligent buildings, production automation, aerospace, military industry, petrochemicals, oil wells, electricity, ships, machine tools, and many other industries. The shortcomings of the existing technology are: after the pressure sensor is installed, it is mostly fixed to the outer surface of the object, which will protrude from the outer surface of the installation object, making it extremely easy for it to come into contact with or collide with the pressure sensor, which can easily cause damage to the pressure sensor and prevent it from working properly. To this end, we have proposed a pressure sensor protection mechanism. Utility Model Content
