  • ... is determined for testing and calibrating acceleration sensors as well as for environmental testing of small assemblies and parts. It is specified to provide sine multi period shock excitations. The HOP-MS works according to the Hopkinson-bar principle. It makes use of the propagation and reflection characteristics of a mechanical wave in a slender bar. The Hopkinson-bar is excited by a piezoelectric actuator.

  • Medium-shock exciter for the amplitude range from 20 gn up to 4,000 gn. This exciter provides the force impact using a piezo-aktuator (patented). This allows new possobilities to control the mechanical shock signal and with its new applications in the field of the calibration and in particular in the field of measurement and test systems (e.g. to test the shock sensibility of MEMS sensors). * patent-protected

Spotlight

The operation principle is the shock excitation of a long and slender metal bar with a piezo actuator and the generation of a longitudinal wave inside of the bar. Due to excitation with a piezo actuator a very precise and controlled pulse can be introduced into the bar. So you can adjust the pulse length and amplitude completely independently.
