  • ... 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.
SE-220 HOP-MS
Acceleration: 20 m/s² ... 40 km/s²

Product Details:

  • Patent-protected
  • 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

In the calibration laboratory for shock-type acceleration excitations, we can calibrate a wide range of different shock-type sensors with varying exciters to suit the specific test object. Alongside a simple impact pendulum, our basic array of equipment also includes fully-automated exciters that meet the state of the art. For high shock-type accelerations, our customers trust in the patented solution of our Hopkinson bar.

 

Scope of services:

  1. Amplitudes up to 200,000 times gravity
  2. Shock impulse widths from 10 ms ... 20 μs
  3. Fully-automated calibration on SPEKTRA shock-type acceleration measurement systems
  4. Calibration with a monopole or dipole shock pulse
  5. Use of a patented Hopkinson bar exciter
