1: Outline
??? The WR series industrial used platinum rhodium thermo-element calls the noble-metal thermocouple, it takes the temperature survey sensor, usually with the temperature transmitting instrument, the regulator and the display instrument and so on necessary use, the anabolie process control system, with or controls in each kind of production process by the direct measurement 0-1800℃ in the scope fluid, the steam and the gas medium as well as the solid surface uniform temperature.
??? The platinum rhodium thermo-element is when joins the return route by two different ingredient's conductor both sides, when two abutment temperatures are different, will produce the thermocurrent in the return route. If the thermo-element working end and the reference end existence has time the temperature difference, the display instrument will make written comments the temperature value which the thermoelectricity pair process the thermoelectric force will correspond.
??? The platinum rhodium thermo-element's heat electrically operated hot will grow along with survey end temperature increment, its size only with the thermo-element material and the both sides temperature related, with the hot electrode length, the diameter has nothing to do with.
??? Each kind of platinum rhodium thermo-element's contour often because of needs, but is not extremely same, but their basic structure actually approximately same, usually by the hot electrode, the insulating cover tube protector and the connecting box and so on principal constituent is composed.

2: Using
??? The platinum rhodium thermo-element is suitable in each kind of production process the high temperature situation, widely applies in the dust metallurgy, the agglutination luminous stove, the vacuum oven, the smelting furnace, the glass, temperature measurements and so on steel-smelting furnace and ceramics and industry salt bath.
