Type R mineral insulated thermocouple cable

Thermocouple cable Type R is a thermocouple junction particularly used at high temperatures. Type R, Pt13%Rh-Pt shares almost the same characteristics as type S (Pt10%Rh-Pt), but type R has roughly 12% higher Seebeck coefficient than type S over much of the temperature range. The temperature range of type R, Pt10%Rh-Pt thermocouples is -50°C ..+1480°C.

For platinum type MI cables like type R, we collaborate with ARi Industries. Their MI cables are designed for use in extremely harsh conditions where typical thermocouple cables fail, the AerOpak® range of mineral insulated cables excels due to its durable construction and selection of corrosion-resistant sheath materials. These cables maintain high performance within the maximum temperature ranges of their materials.

Type R thermocouples are renowned for their ability to accurately measure temperatures ranging from 0°C to 1600°C (32°F to 2912°F), making them a reliable choice in high-temperature environments.

They are especially valued for their long service life and stability, performing exceptionally well in oxidizing or inert atmospheres. However, similar to type S thermocouples, they may experience drift when used over extended periods at high temperatures.

Due to these characteristics, Type R thermocouples find widespread use in industries that require precise temperature control, such as glass, ceramics, and metallurgy. They are also frequently used in laboratory settings and for calibrating other thermocouples, where their accuracy and stability are essential.
