In June, the project "Model-based calibration of accelerometers", which is supported by the Federal Ministry of Economics and Technology (BMWi) and carried out by PTB together with SPEKTRA Schwingungstechnik und Akustik GmbH Dresden ("SPEKTRA Vibration and Acoustic Systems Engineering"), will be launched. The project is promoted within the scope of the Measurement Standards Testing and Quality (MSTQ) transfer programme of the BMWi which supports the technology transfer of innovative measuring methods to small and medium size enterprises (SME).
The object of this technology transfer is novel measuring procedures and methods of data analysis for the calibration of accelerometers as have been developed at PTB over the last years in the two working groups "Realization of Acceleration" (Working Group 1.31) in Braunschweig and "Data Analysis and Measurement Uncertainty" (Working Group 8.42) in Berlin. Contrary to the present calibration methods, the new procedures allow the determination of the input/output behaviour of a transducer also for transient signals, which dominate in industry. The new methods are therefore important and of particular significance to industry because thanks to them, measuring data from different calibration facilities thereby become comparable. At the same time, due to the research results gained at PTB, new opportunities have been created in the field of dynamic calibration methods – which is reflected by the fact that a respective publication has been designated among the "Highlights 2006".
