Type B mineral insulated thermocouple cable

Thermocouple cable Type B is a thermocouple junction particularly used at extremely high temperatures. Type B, Pt30%Rh-Pt6%Rh has some similarities with type S and type R thermocouples, but has lower output than these types of thermocouples at temperatures below 600°C The temperature range of type B, Pt30%Rh-Pt6%Rh thermocouples is -870°C ..+1700°C.

We collaborate with ARi Industries for type B MI cables. Their AerOpak® mineral insulated cables are engineered to perform reliably in extremely harsh conditions where typical thermocouple cables would fail. Featuring durable construction and a variety of sheath materials, AerOpak® cables excel in corrosion resistance and maintain functionality at the upper temperature thresholds of the selected materials.

The temperature range of a Type B thermocouple is approximately 600°C to 1700°C. However, they are known to provide more stable and accurate readings at temperatures above 1000°C, making them particularly suitable for very high-temperature applications.

Type B thermocouples stand out for their resistance to degradation and drift, particularly at extremely high temperatures, compared to other noble metal thermocouples like Types R and S. Their resilience makes them a preferred choice in industries that operate at very high temperatures, such as the furnace industry for temperature monitoring and control, as well as in the glass, steel, and ceramics industries where precise and reliable temperature measurements are essential.
