For many manufacturers, product quality and uniformity are critically dependent upon temperature. Accurate temperature measurement in industry, however, is still a challenge: errors from tens to hundreds of degrees Celsius are possible for processes such as welding, whilst thermometer accuracy can drift over time. For some existing thermometer types and newer optical fibre-based designs, there are few or no current methods to trace their calibration back to primary standards held by National Measurement Institutes (NMIs).
This project will improve the accuracy of a range of thermometer types used in manufacturing, as well as undertaking validation of in-situ references standards for combustion flame temperature measurement. For industrial processes where surface temperatures can reach the 1300 ºC region, methods will be developed with target levels of uncertainty less than 3 ºC, the measurements traceable to standards held by NMI laboratories. With better product uniformity resulting from improved temperature control, European manufacturers will be able to achieve greater efficiency through reduced wastage costs.
