Temperature. Electromotive force (EMF) tables for pure-element thermocouple combinations
What is BS EN 62460 - Electromotive force (EMF) tables about?
BS EN 62460 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. BS EN 62460 also provides the approximate equations for temperature as functions of EMF. Temperatures in BS EN 62460 are based on the International Temperature Scale of 1990 (ITS-90). They are expressed in degrees Celsius, symbol t90. Values of EMF, symbol E/μV, are given in microvolts. The tables and equations in BS EN 62460 are intended for use with thermocouples made from elements of purity not less than 99.999 % for Platinum and Gold and of 99.99 % for Palladium, by weight. Note1: Tolerances on initial values of EMF versus temperature have not been established for the thermocouples in BS EN 62460 . Where required, these tolerances should be agreed between the wire manufacturer and the user. Note2: BS EN 62460 does not cover extension or compensating wires for use with the pure-element thermocouples.
