Yellow And Red Colour Code 22SWG Vitreous Silica Fiber Insulated Type K Extension Wire
Shanghai Tankii alloy material Co., ltd manufactures themocouple wire & extension grade wire, type K, J, T, E, N.
What is the difference between Thermocouple grade and Extension grade wire?
Thermocouple grade wire is wire that is used to make the sensing point (or probe part) of the thermocouple.
Extension grade wire is only used to extend a thermocouple signal from a probe back to the instrument reading the signal.
The extension grade wire typically will have a lower ambient temperature limit in which the wire may be used.
Namely, it may pass a signal representing a higher temperature as received from the probe, but the wire physically may not be exposed to higher temperatures.
Thermocouple wire may be used as extension wire, but extension grade wire may not be used in the sensing point (or probe part) of the thermocouple.
Part numbers for extension wire typically begin with an "EX" prefix.
Remember one thing, Extension Grade wire is only tested and certified to 200C, any usage higher then that cannot be assumed to meet Standard Limits unless the wire is calibrated and the actual tolerance used in determining the final measurement accuracy.
