Abstract
A method for measuring stress applied to a magnetoelastic body, simultaneously detecting a potential external magnetic field affecting a magnetoelastic sensor and allocating a non-stress related influence affected by the field on the body, including applying at least two opposite magnetic zones on the body, providing at least one sensor including at least one first () and second () channel having at least two axially aligned coils each, arranged adjacent to the magnetized zone of the body, both channels having different sensitivity relative to the field, setting-up channelas a common mode rejection channel and channelas a common mode acceptance channel, reading the magnetized zones when stress is applied to the body, measuring the stress by channelleading to an opposite sensitive direction, and detecting the impact of the field to the magnetized zones by channelleading to an identical sensitive direction.
