Abstract

The invention discloses a test tool for a pressure sensor and a using method thereof, belonging to the field of pressure sensors. A test tool for a pressure sensor, comprising a base, the base is fixedly connected with a fixed block, a support plate, a fixed frame, and a mold base, the fixed block is fixedly connected with a motor, and the support plate is fixedly connected with a top plate, The top plate is rotatably connected with a rotary rod, and the motor is rotatably connected with the rotary rod through a transmission mechanism. The top plate is fixedly connected with a slide frame, and the inside of the slide frame is rotatably connected with a cam; the present invention is simple to use and has various detection functions Through the press detection of different pressures on the pressure sensor, the data accuracy of the pressure sensor is effectively improved, and the reliability of the pressure sensor is improved. At the same time, by circulating water on the pressure sensor, the pressure sensor can be The water resistance of the pressure sensor is tested to improve the applicability of the pressure sensor in different environments.

Description

technical field [0001] The invention relates to the technical field of pressure sensors, in particular to a test tool for a pressure sensor and a use method thereof. Background technique [0002] Pressure is one of the most basic parameters for measurement and control in production processes and scientific experiments, and pressure sensors that measure pressure and convert pressure into electrical signals through certain rules become important components for measuring this signal . The reliability of the sensor is very important. It is directly related to the performance of the system using the sensor, affects the quality and speed of production and construction, and even brings serious personal safety problems. During the use of the sensor, its reliability concept can be regarded as failure-free, that is, as the performance summation of the use index that guarantees the limit required by the technical conditions. [0003] When testing the pressure sensor, the accuracy and...
