Guide on Secondary Thermometry: Industrial Platinum Resistance Thermometers



Jonathan Pearce, Richard Rusby, Kazuaki Yamazawa, Stefan Rudtsch, L Iacomini, Giuseppina Lopardo, D Rodney White, Weston L. Tew


This document is a part of guidelines, prepared by the Consultative Committee for Thermometry, on the techniques for approximating the International Temperature Scale of 1990. It collates information on industrial platinum resistance thermometry. The information includes: working principles and construction; associated instrumentation; limitations in performance; and maintenance measures such as annealing and calibration procedures. Particular attention is given to typical performance and sources of uncertainties.
