Thermocouple Type C Tungsten-Rhenium Ф3.2x152mm 2300 °C
Tungsten-rhenium thermocouple alloycombinations were developed to meetthe need for measuring ultra-hightemperatures in the 2315°C(4200°F) rangeThey are 3 widely usedtungsten-rhenium thermocouplealloy combinations:Type G: Tungsten (+) vs. Tungsten 26% Rhenium (–)Type C:Tungsten 5% rhenium(+)vs.Tungsten 26% Rhenium (–)Type D: Tungsten 3% rhenium(+)vs.Tungsten 25% rhenium (–)
Because of the inherent brittleness of unalloyedtungsten, rhenium has been added to the positive leg of types C and D to improve handling characteristics.The average emf of types C and D is slightly less than that of the unalloyed type G.All 3 thermocouple combinations can be used to 4200°F (2315°C) in hydrogen or inert-gas atmospheresand in a vacuum. They deteriorate rapidly under oxidizing conditions and should not be used in air or atmospheres containing oxygen. Resists Many Acids and Weak Alkalies. Very Sensitive to oxidation above 300°C Please note this product contains Berilium Oxide which is a toxic material and therafore no attempt should be made to distantle theunit without first taking the appropriate precautions.Comparative charts:
