Abstract

Abstract: In this paper, the K type thermocouple is taken as the study object. A dynamic experimental system is designed and assembled using the temperature acquisition module and the calibration tester. With the system, the experiment on the dynamic characteristics of the thermocouple is conducted with the experimental data automatically acquired by Visual Basic and Utility software and visualised using Matlab. Based on the experiment, the maximum temperature increasing rates at different wire diameters, insertion depth and testing temperatures are evaluated. Meanwhile, the mathematic model of the thermocouple is set up with the visualization study of the experimental data by Matlab. The study results provide theoretical basis and application guidelines for the installation and maintenance of the thermocouple in thermal power plants.

Key words: thermal power plant, K type thermocouple, dynamic characteristic, numerical simulation
