DBT – Disk Brake Tester

Vibration Technology


The DBT Disk Brake Tester is a free-standing Testing Bench designed to provide a quick and cost-effective NDT analysis of brake rotors.
The heart of DBT is the MG-ST-100 technology, working on the principle of acoustic signature, which provides the right solution for quality inspection (flaw detection) and for dynamic measurements of parts (Squealing and noise control).


Every part, product or component has its unique acoustic resonant signature that reflects its composition, dimensions and stiffness. The resonant frequencies (eigen-frequencies) are almost exactly the same from good part to part, but they will change when internal or external changes occur. With such basis, any deviation from the expected signature indicates a variation of part characteristics and/or manufacturing process.

The DBT can be configured in manual or full automatic mode when loading and unloading can be done with automatic pick-and-place or Robots. External communication is available via Ethernet, USB-3 ports and digital I/O to easily interface the testing bench with auxiliary factory automation and production line.

The entire test cycle takes less than 1 second for each rotor, allowing cost-effective and efficient quality control.
