Limited spaces, ultra-high frequencies in different dimensions, and short amplitudes hinder the integration of conventional sensors. The laser interferometer IDS3010 is capable of measuring high frequen- cy vibrations under limited space conditions. Using more than one mea- surement axis enables the acquisition of relative velocities between different components – the basis for active vibration compensation. The manufacturing accuracy of a milling machine could be increased by reducing the relative velocities of the milling head and the work piece based on their vibrations. Customers can choose: • bandwidth up to 10 MHz – suits high-frequency vibrations of up to 5MHz • linear analog output with a highpass filter for easy post-processing • real-time Fast-Fourier-Transformation (FFT) in WAVE • small sensor heads for machine integration and space-limited applica- tions TYPICAL APPLICATIONS • Vibration monitoring of components in machine tools and semi conductor industries • Synchronous capturing of relative velocities between different components for active vibration compensation • Capturing movements of components for predictive maintenance or condition monitoring
