Description

Technical field[0001]The present invention relates to the field of sensor testing techniques, and more particularly to a temperature sensor response time test device.Background technique[0002]As a super high temperature temperature sensor, its response speed is a very important indicator. The faster the response is, that is, the more sensitiveity of the sensor. Fast corresponding speeds can better control temperature, effectively reduce various losses, or even accidents due to too high temperature or less high.[0003]At present, the temperature sensor response time acquisition, most is through manual score, manually calculate, and manually calculate the cost, and inaccurate and repeatability. At the same time, there may be burnt risks when testing high temperatures. In order to ensure accuracy and reproducibility, there are also some research laboratories to measure and obtain data with high cost. It is difficult to suit the application of enterprises.Inventive content[0004]Based on ...
