THERMOCOUPLE

A thermocouple is used for temperature measurement by joining two different types of conductors to form a closed circuit, which then generates the thermoelectric effect.

THERMOCOUPLE TOLERANCES

According to the standards specified in EN 60584 – 2 and IEC 584 – 2, the tolerance is determined either in °C or as a percentage of temperature, as shown in the table below. The larger of the two specified values is the chosen tolerance.
