Measurement Devices

Thanks to our extensive range of measuring equipment, we are able to delve deeper into unusual tasks, locate causes and develop solutions. In addition to classic measuring devices for vibration and sound measurements, we use the following systems for more detailed investigations.

Motion Amplification Camera

Motion amplification is a non-contact vibration measurement technique. A high-speed camera and special software turn every pixel into a vibration sensor. This allows vibrations to be visualised, recorded and displayed visually based on both time and frequency.

Structural Dynamic Exciter / Shaker

This is an electrodynamic exciter: a mass of around 31 kg is usually set into vibration between 2 and 50 Hz in order to simultaneously measure the response of the structure. The shaker is primarily used to determine dynamic structural properties (natural frequencies, resonance curves, dynamic stiffness, damping behaviour), but transfer functions under continuous excitation can also be analysed.

MEDA

MEDA is a complete programme system for computer-assisted multi-channel measurement and analysis of vibrations, noise and shocks. Among other things, its high resolution allows the wave fronts of shock propagation within supporting structures to be examined.

Impact Hammer

In combination with other sensors (the hammer is equipped with a force sensor) on structures to be measured, vibration frequencies and modes as well as vibration propagation during pulse excitation can be investigated after pulse excitation.

Vibration Velocity Sensors

Standard vibration velocity sensors are used for common applications: To monitor construction sites, to carry out long-term measurements (e.g. for site assessments) and to record and evaluate structural vibrations in bridges, floors, stairs, tall chimneys, etc., as well as trains.

Sound Level Meters

Typical areas of application for short-term and long-term measurements include construction sites, rail and road traffic, concerts and room acoustics testing. The data recorded in the time and frequency domains form the basis for noise assessments (LSV, SIA181 and BEKS) and the development of noise reduction measures.
