Get access to our extensive stock (over 600,000 metres) of Okazaki mineral insulated thermocouple cable. In our warehouse we stock type K, J, T, N, E, S, R, B thermocouple cables sheathed with material varying from Inconel to different types of stainless steel. Also, the more exotic sheath materials, such as Pt10%Rh, Haynes, and Pyrosil are available.
See here how to select the right thermocouple type and the different types of sheath materials for MI cable.
The temperature range of type K, NiCr-Ni thermocouples is -270°C ..+1260°C.
The temperature range of type N, NiCrSil-NiSil thermocouples is -270°C ..+1260°C.
Type J is economically priced and has a smaller temperature range compared to other thermocouple junctions: -210°C .. +750°C.
The temperature range of Type E, NiCr-CuNi thermocouples is -270°C .. +900°C.
In general, Type T has a small temperature range in comparison with other thermocouple junctions: -270°C .. +370°C.
The temperature range of type R, Pt10%Rh-Pt thermocouples is -50°C ..+1480°C.
The temperature range of type S, Pt10%Rh-Pt thermocouples is -50°C ..+1480°C.
The temperature range of type B, Pt30%Rh-Pt6%Rh thermocouples is -870°C ..+1700°C.
A mineral insulated thermocouple cable consists of two conductors (sometimes even four or six) of dissimilar metals. These conductors are joined on the side on which temperature should be measured (hot junction). When properly joined, a voltage is produced that can be read to determine temperature. The dissimilar metals are insulated with high quality magnesium oxide and covered with a corrosion resistant sheath material, such as Inconel or Stainless steel. Mineral insulated thermocouples can provide stable temperature measurement readings and are often used for high temperatures (up to 1250⁰C) in hazardous environments.
