A contactless measurement sensor basing on the magneto-elastic effect to diagnose the torsional moment of magnetizable, axially symmetric tools delivers solutions of so far not solved problems of materials specific hysteresis effects and perturbations in the dynamic operation.
Complete contactless and therefore ...
- independent of compressive and tensile stress,
- independent of electric conductivity of the tool,
- no hysteresis effects,
- not interference-prone at extreme conditions
