Technology

Magnetic field measurement at a world-leading level

The B-TECH sensor head measures the magnetic flux density in all three spatial directions. From the measured field we reconstruct the direction and strength of electric currents – contactless, quantitative and non-destructive. The basis is a patented Fraunhofer technology.

01 / 03

Non-destructive & contactless

Measurement in seconds, without opening or damaging the sample.

02 / 03

Quantitative & precise

Resolution down to 0.3 µT – direction and strength of currents exactly determined.

03 / 03

Lab to production

Scalable from research setup to integrated inline inspection.

Applications

What the technology reveals

From the measured magnetic field, B-TECH reconstructs the direction and strength of electric currents – producing insights other methods cannot deliver, across many industries.
