Standards and Technical Documents - Temperature - Electromotive force (EMF) tables for pure-element thermocouple combinations -- IEC 62460:2008
Description: IEC 62460:2008 specifies the equations and reference tables relating temperature to EMF (electro-motive force) for Gold versus Platinum and Platinum versus Palladium thermocouples. For information and convenience of use it also provides the approximate equations for temperature as functions of EMF.Show More
Standards and Technical Documents - Measuring Thermoelectric Inhomogeneity In Thermocouples - 51st Iis 2005
Description: the benefit of inhomogeneity testing. Additionally, thermoelectric inhomogeneity, the spatial non-uniformity of thermoelectric sensitivity, is present in all thermocouples, including elemental thermocouples such as Gold versus Platinum, and the error due to this condition cannot be correctedShow More
