Measurement and analysis of machines and mechanisms

We offer services in the field of measurement and analysis of dynamic behaviour of machines and mechanisms. We design and use high-tech measurement technology that enables multichannel measurements of dynamic quantities and their evaluation in the time and frequency domain in real time or in subsequent signal processing.
