When access to a third metal material in the thermocouple circuit, the thermoelectric material as long as the two contacts of the same type K thermocouple temperature wholesale, generated by the thermocouple is bound to remain unchanged, that is not the third metallic access loop of. Therefore, when the thermocouple, can access the measuring instruments, measured after thermal electromotive force, to know the temperature of the measured medium. Thermocouple to measure the temperature requirements of its cold end (measuring end of the hot end. 2, insulation deterioration and the introduction of error, such as a K-type thermocouple thermocouple insulation specifications, protection tube and pull plates causes excessive dirt or salt slag thermocouple very poor insulation between the walls and the furnace is more severe at high temperatures, it will not only cause the loss of the thermoelectric power but also the introduction of interference, the error resulting sometimes up on Baidu. K-type thermocouple measuring force since prices _ Miriam K-type thermocouple type K thermocouple _ Hunan force measured by Shanghai Automation Instrumentation Co., Ltd. Shanghai Automation Instrumentation Co., force measurement (www.licesh.com) is the Shanghai Zhabei District, flow meters leaders, over the years, the company is implementing implementation of scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. In force since the instrument measuring leadership with the staff warmly welcome all inquiries negotiations to create the force measuring instrument since a better future.
