Abstract

The invention relates to a response time calibration technology of a temperature sensor, and specifically relates to a response time calibration device of a temperature sensor. The response time calibration device of the temperature sensor solves the problems that calibration precision is low when an existing response time calibration method of a temperature sensor calibrates a small-response-time temperature sensor, reliable response time cannot be obtained, and accuracy of response time obtained in a flame temperature field environment is low. The response time calibration device of the temperature sensor comprises a longitudinal linear guide rail, a slide block with a pulley, a vertical small baffle plate, a vertical big baffle plate, a rapid adsorption sheet, a rapid ejection device, a temperature sensor, a compensation lead, a signal acquisition and processing integration circuit, a data transmission line, a data display device and a flame temperature source. The response time calibration device is suitable for performing response time calibrations of the temperature sensor in various environments, and is especially suitable for performing the response time calibration of the temperature sensor in the flame temperature field environment.

Description

technical field [0001] The invention relates to a response time calibration technology of a temperature sensor, in particular to a response time calibration device of a temperature sensor. Background technique [0002] In the transient temperature measurement under special environment (such as high temperature, high pressure, strong ionization environment), the temperature sensor used is required to have the characteristics of good dynamic response characteristics, small heat capacity and almost no interference to the test environment. Among them, the dynamic response characteristics of the temperature sensor have received much attention, and the response time of the temperature sensor is the main index reflecting its dynamic response characteristics. Therefore, in order to measure the transient temperature accurately, it is necessary to calibrate the response time of the temperature sensor used. Under the existing technical conditions, the response time calibration methods...
