Technology

Cable colors for compensating leads

Different colors are used for the compensating leads corresponding to the various types of thermocouples. Although there is an international European standard (DIN IEC 485), many cables are still manufactured and used according to national standards. The most important ones are summarized in the following table.

Polynomials for temperature calculation according to ITS-90

To calculate the temperature from a measured thermoelectric voltage at a reference junction temperature of 0°C, polynomials of up to the 14th order are used. These polynomials are shown in the following table. The polynomials can also be obtained from us as a text file, allowing you to integrate them into your own programs without errors.
