Abstract

The invention discloses a pressure sensor testing tool and a using method thereof, and belongs to the field of pressure sensors. The pressure sensor testing tool comprises a base, wherein a fixing block, a supporting plate, a fixing frame and a die holder are fixedly connected to the base, a motor is fixedly connected to the fixing block, a top plate is fixedly connected to the supporting plate, arotating rod is rotatably connected into the top plate, the motor is rotatably connected with the rotating rod through a transmission mechanism, a sliding frame is fixedly connected to the top plate,and a cam is rotatably connected into the sliding frame. The pressure sensor testing tool is simple to use and diversified in detection function, the data accuracy of a pressure sensor is effectivelyimproved and the reliability of the pressure sensor is improved by performing pressing detection of different pressures on the pressure sensor, and meanwhile, the waterproofness of the pressure sensor can be detected by performing circulating water spraying on the pressure sensor, and the applicability of the pressure sensor in different environments is improved.

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...
