Abstract

The invention discloses a testing device, which comprises at least one test unit, wherein the test unit comprises a bearing seat body and a buckling seat body, a bearing groove is formed in the bearing seat body, and is used for placing a to-be-tested differential pressure sensor, a first ventilation channel is formed in the bearing seat body, an opening in one end of the first ventilation channelis formed in the inner wall of the bottom of the bearing groove and is used for hermetically communicating with the first gas inlet end of the to-be-tested differential pressure sensor, the bucklingseat body is arranged on the bearing seat body, and a second ventilation channel is formed in the buckling seat body, is communicated with the notch of the bearing groove, and is used for being communicated with the second gas inlet end of the to-be-tested differential pressure sensor. According to the invention, test gas is correspondingly input into the first gas inlet end and the second gas inlet end through the first ventilation channel and the second ventilation channel which are independent of each other to simultaneously input the test gas to the two sides of the to-be-tested differential pressure sensor, so that the performance parameters of the to-be-tested differential pressure sensor can be conveniently obtained, and the test requirements of the differential pressure sensor aremet.

Description

technical field [0001] The invention relates to the technical field of sensor testing, in particular to a testing device. Background technique [0002] During the performance test of the differential pressure sensor, the product is usually placed in a sealed test chamber, and the same air pressure value is input to the entire test chamber for testing. Since only one air pressure value can be controlled in the entire test chamber at the same time, The testing requirements for this product cannot be met. Contents of the invention [0003] The main purpose of the present invention is to propose a test device aimed at optimizing the existing test device to meet the testing requirements of the differential pressure sensor. [0004] In order to achieve the above object, the present invention proposes a test device, comprising at least one test unit, the test unit comprising: [0005] The bearing base has an installation side, and a bearing groove is formed on the installation ...
