About the classification of the platinum rhodium thermocouple and use

Platinum rhodium thermocouple conductor is mainly composed of two different components, end will be combination of circuit, when two juncture in different temperature, thermal current will appear in the circuit. And if work end and reference end of thermocouple temperature difference exists at the same time, so the reality instruction of instrument will be directly out of the corresponding temperature value because of the thermocouple. And platinum rhodium thermocouple in the heat of electric heat, because on the temperature measuring end of change and ascension, it in fact only and the size of the thermocouple materials, as well as the existing relationships on both ends of the temperature, and thermal electrode length and diameter and so on all has nothing to do. Various platinum-rhodium thermocouple often because of different in shape, and lead to its on the use of different, but in its basic structure is the same, under normal circumstances, is by protecting tube, thermal insulation sleeve grounds for electrodes and the junction box and combination. Platinum rhodium thermocouple is suitable for use in a variety of production process, relatively high temperature occasion, is widely used in the sintering process, the light, powder metallurgy, vacuum furnace, glass furnace, ceramic, steel furnace, melting furnace and industrial salt bath furnace, etc.
