Thermocouple Cables

Part 2 Type 1 PVC Insulated Unscreened PVC Sheathed Thermocouple Cables

Application :
Thermocouple Cables are sensor for measuring temperature, that consists of two dissimilar metals that are joined together at the sensing end. They can be employed as the thermocouple hot junction in addition to serving as the entire wire connection between hot and cold reference junctions.
