After years of development we have realized QASS µmagnetic, a completely new micromagnetic measuring concept for non-destructive hardness testing. We utilize the Barkhausen noise, that is known for decades, which means ongoing interaction ferromagnetic materials by using an external magnetic field. This is combined with very high sampling rates and our real-time spectral analysis.
Determine the hardness of your purchased materials and conduct a reliable Positive Material Identification. Analyse non-destructively the hardness condition of ferromagnetic components and materials with QASS µmagnetic. Due to the one-time calibration of the QASS µmagnetic to your materials, a reference condition is set whereby the hardness can be shown in Rockwell, Brinell or Vickers.
Verifiable: Non-Destructive Hardness Testing – Also Contactless
QASS µmagnetic measures via direct contact or even with an air gap between sensor and component. The QASS software compensates known distances, which could influence measuring values.
Thereby we are able to detect the hardness of ferro-magnetic materials even under noisy and unsettled conditions. The detailed analysis is shown in a transparent 3D-landscape with the axes frequency, time and amplitude. The numbered result is user-friendly visualized as a single value. The measurement system enables a contact-less hardness measurement in real-time, directly on the component and under production conditions.
A measurement on parts that move during production is possible, for example, when rotations or linear movements are used. The new sensors by QASS can be customized to the customer’s needs and processes. Contact us – we will find a solution.
