Product Overview


Type K/ Type T/ Type J thermocouple extension wire/cable


Product Description


Thermocouple extension wire is used to extend the thermode, that is, the cold junction of the movable thermocouple connect with indicating instrument to make up temperature measurement system.


Extension wire falls into two kinds; one is extension type and the other is compensation type. The wire same with the two thermocouple wires of the Graduation Mark, is know as the extension type. The wire same with, formed by cooper----cupronickel materials with different proportion, is called compensation type.


The two kinds of extension wire, both have good property of resistance to acid, alkali, abrasion and fire. It's temperature range used commonly is -25-400C. In addition, it can be used for a long time by immersing into the oil. The extension wire complies with GB/T4989-94-2016 standard.


The extension wire types can be divided into WC, BC,SC, RC, NX, KC, KX, EX, JX and TX in accordance with the product type.
