Abstract
The article analyzes domestic and foreign thermoelectric converters (thermocouples) for measuring the temperature of the rubber in rubber mixers. The advantages and disadvantages of existing thermocouple designs are considered, and the thermocouple design developed by Point LLC is presented. A comparative analysis of the influence of the material of thermocouple tips, the coating material of the tips and the diameter of the thermocouple wires on the strength characteristics of the finished product, as well as on the indicators of the thermal lag index, is presented. The results of tests for temperature inertia of the developed thermocouples and its analogue are shown. Recommendations are given for conducting pilot-industrial operation during the development and research of new designs of thermocouples for rubber mixers. The results of a joint test of a thermocouple from Point LLC and a foreign analogue are shown in the form of a temperature trend.
