What is thermocouple extension wire?
Thermocouple extension wire is used to carry the signal from the thermocouple sensor to the readout device while maintaining a high degree of accuracy. The extension wire material must match the material used in the positive and negative leg of the thermocouple type (e.g. type K) being used in the application.

What is a Type K connector?
TE Connectivity K-Type Thermocouple Connectors provide an easy connection with thermocouple wires. The spring terminal concept of these connectors offers outstanding connectivity compared with traditional screw-type terminations. TE K-Type Thermocouple Connectors provide a push-on lock concept for easy mating.
Can I use regular wire to extend a thermocouple?
Do not extend the lead wires with compensating conductors that do not suit the characteristics of the Thermocouple, or with ordinary lead wires, as this would prevent proper temperature measurement. Be sure also to connect the wires using the correct polarity (+/-).
Which wire is positive on a thermocouple?
The insulation on thermocouple wire is color coded for identification. Common guidelines include that the negative lead in insulated thermocouple wire is red. The positive lead has the color of the thermocouple as well as the overall color of insulated extension grade wire.
How do you test a type N thermocouple?
Place one test lead on the side of the thermocouple and the other to the end that screws into the gas valve. If the thermocouple has proper continuity, a small resistance reading should be visible on the multimeter. Many multimeters also indicate continuity with an audio alert.
How many types of thermocouple wires are there?
Thermocouple Wire Types
| Type | Conductors | Temperature Range |
|---|---|---|
| (+) Leg | Max | |
| R | Copper | 1768°C / 3214°F |
| S | Copper | 1768°C / 3214°F |
| B | Platinum- 30% Rhodium PT- 30% | 1820°C / 3308°F |

What is a thermocouple fitting?
Thermocouple Connectors ensure the Temperature measurement signal (millivolts) from the thermocouple sensor or lead wire is accurately transmitted to the display or control Instrumentation.
