Ceramic High-Temperature Thermocouple R, S, And B Assemblies. Thermocouple Are Made From Conductors Containing Platinum And Rhodium Alloys And Are Suited For Measuring High Temperatures Up To 1700°C.

Ceramic High-Temperature Thermocouple Type R And Type S Technical Details

Type R And S Ceramic Thermocouples Are The Most Popular Rare Metal Thermocouple Types. They Are Very Similar In Conductor Construction. As The Cost Of Platinum And Rhodium Is High In Comparison To Base Metal Thermocouples, Type R & Type S Wire Can Be Recovered And Recycled From Failed Thermocouples. The Negative Leg On A Type R Or S Thermocouple Is Pure Platinum And The Positive Leg Is Platinum / Rhodium.
