The working principle of thermocouple _ instrument
The thermocouple thermoelectric emfs growth over the course of measuring the temperature, the size of the thermoelectric emfs and thermocouple temperature difference on both ends of the conductor material and, only has nothing to do with hot electrode length and diameter. The structure of the thermocouple is made even wire, insulation of magnesium oxide and by repeated drawing stainless steel protecting tube. Thermocouple products are mainly composed of terminal block, terminal and thermocouple basic structure, and with various mounting device. Thermocouple insulation type and hull type two kinds. Two different ingredients of conductor on both ends of the welding, forming circuit, direct measuring WenDuan measuring head, terminal said reference. When measuring the temperature difference is with the reference, the will produce thermoelectric potential in the circuit, digital display table is connected, digital display table will indicate the thermocouple thermoelectric emf generated by the corresponding temperature value.
During the exhibition season, the company team, with company letter product thermocouple, thermal resistance electronic temperature and other products, visited our company's European and South American customers, meet with old customers at the exhibition, new products are welcomed by old customers; should be invited, visit customer company, deepen The understanding of both sides is for further cooperation.
