Metrology to reduce thermal effects and drift in precision engineering

摘要

Current state of the art temperature measurement equipment needs regular re-calibration, which increases the down time of instruments and the costs in industrial production. Therefore, in September 2011 the European Union started a project for a three year period to analyse drift effects including aging, thermal expansion, temperature dependence of hardness and creep of materials, joints and sensors. The aim is to contribute to a metrological knowledge base for material properties and related metrological standardisation. It encompasses a multitude of national metrology institutes (NMI) and other stake holders. Collaborators are welcome to join the project.
