Abstract
A magnetoelastic force-measuring device is proposed which has an annular thrust body possessing magnetostrictive properties and bearing a ring coil. To enhance the measuring sensitivity in conjunction with simultaneous good thermal error compensation, a sleeved tension body, likewise possessing magnetostrictive properties and bearing a ring coil, is arranged coaxially in the annular thrust body to fit in such a way that, given the introduction of a force, the one body is subjected to thrust and the other to tension. In this connection, the magnetostrictive properties are formed by a soft magnetic measuring film--preferably of amorphous metal--which applied in each case to the body, and the two ring coils are connected up to make an inductive half-bridge.
