Vibration and Noise in Machines and Electro Technical Systems - Measurement, Calculation, Analysis, Monitoring, Testing, Qualification and Reduction

For decades, Wölfel has been successfully active in the field of machine and (electrical) systems engineering - both for manufacturers and operators of machines and systems.

We advise our customers in solving problems related to vibration and noise. Our experts can support you from the first measurement to the clarification of the problem to the execution of computational analyses, the conception of feasibility studies to the delivery of individual products or systems to solve your problem.

Examples of customer projects "Measurement" and/or "Environmental Test"
