Table 2 Notation and characteristics of thermocouples ...

The tests with W–Re and IrRh/Ir thermocouples demonstrate that the newly developed Ru–C cells can be used to successfully realize melting plateaux repeatedly. This enables the longterm drift measurements essential for the evaluation and improvement of hightemperature thermocouples. The results obtained in this study will also be useful for evaluating the uncertainty of thermocouple ...

Precious Metal Alloys in HighPerformance Applications ...

Iridium can also be alloyed with rhodium to make up iridiumrhodium (IrRh) alloys, which are largely used in the automotive industry as highperformance spark plug materials and also as hightemperature thermocouples. Another platinum alloy uses gold as an alloying element. Gold, in and by itself, is a soft metal, just like platinum. However, when alloyed together, gold can harden platinum ...

Thermocouple : fonctionnement Ooreka

Thermocouple : le « coupegaz » du chauffeeau. Organe de sécurité, le thermocouple est présent sur les chauffeeau équipés d''une veilleuse. Il se positionne dans la flamme et détecte sa présence par la chaleur quelle dégage. Lorsque la flamme s''éteint, il coupe l''arrivée de gaz et empêche ainsi le chauffeeau de se mettre en route.
