Abstract
The invention provides a sensor assembly for force sensing, the sensor assembly comprising: a first portion having a first and a second through hole, a second portion having a third and fourth through hole, and a first pin and a second pin coupling the first portion to the second portion. At least one out of the first and the second pin comprises a magnetoelastic based sensor for outputting a signal corresponding to a stress-induced magnetic flux emanating from a magnetically polarized region of the pin. The magnetoelastic based sensor comprises at least one direction sensitive magnetic field sensor in an at least partially hollow portion of the pin, which field sensor is configured for determination of a shear force in at least one direction. The invention further provides a tow coupling comprising the sensor assembly. The invention further provides a method for detecting a load.
