How to Identify a Thermocouple by Wire Color

There are many types of thermocouples, each with its own unique characteristics. You can easily identify a thermocouple type by the colors of its wire insulation. In this video we’ll be focusing on the ANSI wire color coding used by the United States and Canada.In ANSI color coding, the red wire of a thermocouple is negative, and the positive wire is color coded to the type of thermocouple.

Could u kindly give us the resistive vale chart for all these kind of thermocouples.

my wires go into a potted mess of epoxy. Ive no way to see colors of wires. any other ideas on how to determine?

Check with a magnet. One will be magnetic, the other won’t be. But I can’t figure out which is which

This is very useful, thanks. Can I replace old 'k 'type with new 'j' type without changing PID(temperature controller). (Process temperature 0-200 deg celsius )

Only if your PID controller is compatible with Type J thermocouples. Many PID controllers will work with different thermocouple Types, but there are some that will only work with one thermocouple Type. If your PID controller will work with different thermocouple types other than just Type K then you'd need to change the Controller's input type setting from Type K to Type J. To perform this task we suggest you consult with the PID controller's user manual or the manufacturer.

I have a multimeter with a type k thermocouple. It’s a flimsy little wire. I also have a few spare thermocouples used in kiln that are type k. Can I use one of the larger kiln thermocouples with my multimeter. Will it read the temps the same as the little wire one ? I want to use it to test my kilns when I suspect a thermocouple is starting to go bad, but I don’t think the little flimsy wire one would hold up.
