TWO THERMOCOUPLES SUITABLE FOR MEASUREMENT OF TEMPERATURES UP TO 2800 C
The thermoelectric characteristics of two hightemperature thermocouples of tungsten/26% rheniumtungsten and tantalum/26% rhenium-tungsten are described, and a method of determining the e.m.f. of the couples up to a temperature of 2800 deg C is given. In the temperature range 1000 to 2000 deg C, the sensitivity of the tungsten/rhenium-tungsten couple is 16.2 mu V/ deg C and that of the tantalum/rhenium-tungsten couple is 13.6 mu V/ deg C. The important feature of these thermocouples is their suitability for operation at much higher temperatures than existing couples, combined with a fairly high sensitivity. (auth)
