Problems solved by technology

At present, the thermal response test of the thermocouple on the star (on the spacecraft) needs to be connected to the measuring instrument of the thermal test measurement and control system before the thermal test. There is a lack of sufficient verification means in the final assembly stage, and the results can only be guaranteed by strengthening process control. Once a problem occurs, it will bring a lot of inconvenience to take remedial measures in terms of time and space; the thermal response of thermocouples such as brackets and tooling is generally used to touch the thermoco

Abstract

The invention discloses a thermocouple thermal response tester, which comprises a thermocouple test host and a handheld heater, wherein the thermocouple test host comprises a signal introduction connection unit, a temperature measurement and control unit, a data acquisition unit, a data processing unit, a data storage unit, a host data transmission unit, and a man-machine interaction unit; and the handheld heater comprises a heating unit, a heating control unit, a data display unit, and a heater data transmission unit. 48-channel thermocouple temperature data can be measured at the same time, the thermocouple can be heated, the measured data are stored, and when the tester is used for thermocouple thermal response test, the existing operation can be simplified, and the working efficiency and the accuracy in the case of thermocouple thermal response test operation can be improved.

Description

technical field [0001] The invention belongs to the technical field of spacecraft thermal test and measurement devices, and in particular relates to a thermocouple thermal response tester. Background technique [0002] The thermal response of the thermocouple is through the thermoelectric effect of the thermocouple, and the temperature of the temperature measuring end of the thermocouple is changed by a certain heating method, and then the correctness of the test preparation result is verified by measuring the change of the characteristic value of the corresponding pin of the electrical connector. At present, the thermal response test of the thermocouple on the star (on the spacecraft) needs to be connected to the measuring instrument of the thermal test measurement and control system before the thermal test. There is a lack of sufficient verification means in the final assembly stage, and the results can only be guaranteed by strengthening process control. Once a problem oc...
