Using thermocouples to measure high temperatures accurately over extended periods has always been a challenge due to thermocouple drift. A new technology, called low drift dual wall thermocouples, developed in the Department of Materials Science and Metallurgy at the University of Cambridge and licensed to TE Wire & Cable (see also www.marmonelectrical.com/ground-breaking-thermocouple-cable-technology), a Marmon Group/Berkshire Hathaway Company, allows to overcome at high temperatures the limitations of conventional mineral insulated metal sheathed thermocouples.

Compared to conventional mineral insulated type K and type N thermocouples the low drift dual wall thermocouples provide:

• Reduced drift

• More accurate temperature measurement

• Longer life

ISOMIL is the only mineral insulated cable manufacturer for the low drift dual wall thermocouples. Low drift dual wall thermocouples can be obtained through:

• TE Wire & Cable

• CCPI Ltd

• Directly through ISOMIL
