Common thermocouple types thermocouple. Thermocouple wire colour chart. For example if you need a j type thermocouple a pairing of constantan and iron you ll want to use the red white thermocouple wire to go with it. Commercial thermocouples are inexpensive interchangeable.

Every standard thermocouple type has a universally accepted standard colour pair. Four factors determine the useful service temperature for omegaclad assemblies. Different colors for insulation and lead wires also indicate the thermocouple grade and extension grade. This chart shows each thermocouple type and its estimate millivolt output vs temperature.

Although thermocouple calibration dictates the temperature range the maximum range is also limited by the diameter of the.
