Abstract
A magnetoelastic shear force transducer with an interference field compensation comprises a hollow component section having an interior recess. A load can be applied onto the hollow component section. The load causes a shear stress in the hollow component section. The hollow component section includes at least one annular magnetoelastically active section having a magnetic polarization surrounding the recess and magnetoelastic properties. Magnetic-field sensors include at least one magnetic-field sensor in the magnetoelastically active section and a magnetic-field compensating sensor associated with the magnetic-field sensor in the magnetoelastically active section. The magnetic-field compensating sensor is arranged outside the magnetoelastically active section. A sensor signal of the magnetic-field sensor is processed along with a compensating signal of the magnetic-field compensating sensor to reduce the influence of an interfering magnetic field. A method of determining an optimum distance between the magnetic-field sensor and an associated magnetic-field compensating sensor is also disclosed.
