What is Thermocouple Extension Wire
Thermocouple grade wire is wire that is designed 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 TC grade wire typically will have a lower ambient temperature limit in which the wire may be used.
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.
What is the difference between Thermocouple Grade Wire vs. Extension Grade Wire?
Thermocouple grade wire is used to manufacture thermocouple probes.
Thermocouple grade wire is normally used for the junction and inside the stem sheath. This is because the thermocouple grade wire has a accuracy specification than extension grade wire.
Extension grade wire is a less expensive, lower grade wire. It is used to extend from the thermocouple probe to the control system or digital display. Extension grade wire is more economical due to the length requirements. Also, it is not in the process itself and does not play as critical a role nor does it experience the temperature extremes & temperature cycling.
In many industrial applications a sensor is located in a process pipe far away from the control room. This means a wire must be run a considerable distance back to the control room to get the temperature reading. Using more expensive thermocouple grade wire to accomplish this is unnecessary. Extension grade wire will do the job.
