Questions of metrological assurance of temperature sensors made of platinum and platinum-rhodium wire manufacturing

In paper three basic questions related with metrological assurance of temperature sensors made of platinum and platinum-rhodium wire manufacturing are considered. The questions are: practical use of wire W100 parameter, estimation of wire unheterogenity in thermo-emf, current definition of nominal state characteristic for type S thermoelectric transducer. Authors describe current state of affairs in area under consideration and offer ways of elimination of inconsistency in wire manufacturers and consumers standards. The paper in many respects based on results of Siberian State Institute for Metrology (Novosibirsk) and JSC Krastsvetmet (Krasnoyarsk) joint researches. The characteristics of methods and instruments recently used by JSC Krastsvetmet to control platinum and platinum-rhodium wire parameters are given. Its shown that reached reliability of the control is sufficient. The attention to possible necessity of redefining of nominal state characteristic for type S thermoelectric transducer is paid.

Keywords: temperature sensor, unheterogenity, platinum wires, and platinum-rhodium wires, nominal state characteristic of conversion.
