Title:
METHOD AND ASSEMBLY FOR DETERMINING THE ROTATIONAL SPEED OF FERROMAGNETIC COMPONENTS
Document Type and Number:
WIPO Patent Application WO/2013/045247
Kind Code:
A3
Abstract:
The invention relates to a method for determining the rotational speed of ferromagnetic discs (2) via the detection of permeability changes in dependence on radially directed forces (σ) in the disc, wherein, for measurement, at least one contactless-operating magneto-elastic sensor (1) is oriented toward a face of the ferromagnetic disc (2) to be measured, to detect permeability changes in the case of occurring radial forces, and to calculate same. The primary use of said invention is in the field of contactless data determination of rotating components.
