Methods and Measurement Technology
Vibration Measurements
Recording of displacement, velocity, acceleration, strain and dynamic stiffness with almost any number of channels, resolution down to 10 nm/s (1–315 Hz).
Third-Octave Monitoring
Real-time frequency spectra with two-stage alarming for the protection of vibration-sensitive equipment on construction sites and in operation.
Artificial Excitation
Excitation of structures with VibroTruck, Butterfly-Shaker or unit impulse generator for dynamic characterization and prognosis.
FEM Analysis
Finite element modeling of the structure for vibration simulations, prognoses and structural concepts.
Expert System EProg
Vibration prognosis for road and civil engineering works by combining on-site measurement with a database of construction machinery emissions.
Expert Reports
Expert reports on structural dynamics and vibrations, reviewed under the four-eyes principle.
