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. Range for the thermocouple wire see table of error maximum service temperature of. A thermocouple is an electrical device consisting of two dissimilar electrical conductors forming an electrical junction a thermocouple produces a temperature dependent voltage as a result of the thermoelectric effect and this voltage can be interpreted to measure temperature thermocouples are a widely used type of temperature sensor. Difference in thermocouple types each calibration has a different temperature range and environment although the maximum temperature varies with the diameter of the wire used in the thermocouple.

Thermocouple type comparison chart. This chart shows each thermocouple type and its estimate millivolt output vs temperature. Four factors determine the useful service temperature for omegaclad assemblies. The white wire is iron.

This is the most common thermocouple type that provides the widest operating temperature range. Bare thermocouple wire and extension wire conductors based on ohms per foot at 70 f note.
