Abstract
The invention relates to a sensor, in particular, a magnetostrictive or magnetoelastic sensor, comprising at least one core element which consists of a ferromagnetic material. Said core element is at least partially surrounded by at least one coil. The core element or elements are placed into a housing which is subjected to tensile and/or pressure forces, in order to determine the moment of force and/or the torque.
Claims5
A sensor comprising at least two core elements (8.1 to 8.3) which are composed of a ferromagnetic material and are at least partially surrounded by at least one coil (10.1 to 10.3), wherein the two core elements (8.1, 8.2) are inserted into a housing (1), arranged in a row one behind the other, in which case external tension and/or compression forces can be introduced axially via an intermediate piece (6) which is arranged between the two core elements (8.1, 8.2), the intermediate piece (6) has at least one associated force transmitting element (13), which projects radially out of the housing (1) and can move infinitesimally axially in an opening (14) in the housing (1).
