A thermoelectric series is an ordering of thermocouple elements in such a way that when any pair of materials in the series is used to form a thermocouple, Seebeck current at the cold junction flows from the member occuring earlier in the series to that occuring later. One should be careful in using the series as the opposite convention is sometimes used. As one uses pairs of members which are closer in the series, the thermoelectric yield goes down when one reduces the temperature difference. The following table gives the thermal emf (in  ) with respect to Platinum when the cold junction is at  C while the hot junction is at  C. |
