Seismology and Geoscience

The broad field of seismology and geoscience requires a range of high-tech equipment that makes it possible to detect even the smallest earth movements in the first place. Permanent seismic monitoring makes it possible to localize potential hazards and establish effective long-term protection against the effects.

We offer a broad, specialized portfolio of products and services worldwide for this topic with its utmost social importance. Our service range includes support in the development of new seismometers, certified calibration and structural excitation for seismological research and equipping entire laboratories.

Modal Exciters

Excitation of larger structures

To investigate possible effects of seismic movements on structures or industrial plants, our APS modal exciters can be used to excite large structures in a targeted manner. Optional accessories allow the exciters to be applied in different working modes such as free body mode or fixed at angles between 0° and 90°. Optional reaction masses can be used to additionally increase performance.



Characterization and Calibration

The performance of our DAkkS-accredited calibration laboratory D-K-15183-01-00 is among the best worldwide. You receive reliable, traceable calibration certificates with the lowest possible measurement uncertainties. Factory calibration and verification for your required international or local standards is also possible on request.

  • Seismometers and seismic measurement chains in the frequency range 0.1 Hz…400 Hz
  • Geophones and vibration meters 0.5 Hz…315 Hz
