Pulse transducer mfr. method - producing alternating regions of different magnetic properties on component by structural heat treatment

摘要

In the method producing alternating regions (2, 3) of different permeability and/or remanence are produced on a component (1) by heat treatment with structural alteration. For use as a pulse transducer for angular rate sensing a steel counter ring is made with regions of different magnetic properties arranged about the circumference and at equal intervals. USE/ADVANTAGE - For contactless detection of pulses using magnetic arrangement, e.g. for revolution rate of angular position measurement. Compact transducer is produced using simple process to make magnetic markings.
