Abstract

The invention discloses a double-range high-precision pressure sensor, which comprises a base, a fixed plate is movably connected into the base; the top of the fixing plate is vertically and fixedly connected with a supporting rod. Placing grooves are formed in the positions, located at the top and the bottom of the fixing plate, in the base. And a fixing pull frame is arranged in the placing groove, a sensor fixing frame is arranged on one side of the fixing pull frame, a first pressure sensor is arranged in the sensor fixing frame at the top of the fixing plate, and a second pressure sensoris arranged in the sensor fixing frame at the bottom of the fixing plate. According to the double-range high-precision pressure sensor, the problems caused by installing sensors at the top and the bottom in the prior art when pressure testing is carried out on a vibrated object are solved, and the working efficiency of experiments is improved.

Description

technical field [0001] The invention relates to the technical field of sensors, in particular to a double-range high-precision pressure sensor. Background technique [0002] A sensor is a detection device that can sense the measured information and convert the sensed information into electrical signals or other required forms of information output according to certain rules to meet the requirements of information transmission, processing, storage, and display. , recording and control requirements, the characteristics of sensors include: miniaturization, digitization, intelligence, multi-function, systematization, and networking. It is the first link to realize automatic detection and automatic control. The existence and development of sensors allow objects to have senses such as touch, taste, and smell, and make objects come alive slowly. Usually according to its basic perception function, it can be divided into ten categories such as thermal sensor, light sensor, gas sens...
