A temperature sensing element is a primary instrument, the direct measurement of the temperature of the thermocouple. Closed loop by two different components of the composition of the conductor material, due to the different materials, different electron density generated electron diffusion, after generating a stable equilibrium potential. When there is a temperature gradient at both ends, there will loop currents, thermal electromotive force generated, the greater the temperature difference between the standard thermocouple main current will be. To know the temperature values ??measured after thermal electromotive force. Thermocouple is actually an energy converter, can convert heat into electricity. Not installed correctly, the thermal conductivity and time lag error standard thermocouple distribution, which is the main error of the thermocouple in use. 4, when the high temperature thermal error, such as a layer of ash on the protection tube, dust attached to the above standard thermocouple prices, the increase in the standard thermocouple thermal resistance, resistance to heat conduction, when the temperature is shown true value than the measured temperature value is low. Therefore, we should keep the outside clean thermocouple protection tube to reduce errors. Standard thermocouple manufacturers, power measuring instruments since quality assurance (certified), Chongqing standard thermocouple measuring the force provided by the Shanghai Automation Instrumentation Co., Ltd. Shanghai Automation Instrumentation Co., force measurement (www.licesh.com) (http://www.licesh.com) is the Shanghai Zhabei District, flow meters leaders, over the years, the company is implementing the scientific management, innovation and development, honesty and trustworthiness policy, and satisfy customer needs.
