MULTIPAIR THERMOCOUPLE EXTENSION / COMPENSATING CABLES

A Thermocouple measuring point is formed by joining two dissimilar metals as one circuit, which when exposed to different temperatures generates a net thermal electromotive force ( E.M.F.) Each thermocouple cable has two cores of such dissimilar conductors forming a pair and for multiple measuring points multi pair cable is used.

‘Udey’ offers the complete range of cables suited for High Volt & Temperature application with various combinations of different conductors, insulations and shields as as per customer application & requirement.
