Abstract

A force sensor device for determination of a measurement value of a force and generation of an electrical signal based on the measurement value includes a force ring with a force application surface and a support surface for support of a circuit board, on which passive and active electronic components are arranged. The circuit board is mechanically or adhesively fixated on the support surface. At least one force transducer is electrically connected with the circuit board, and arranged and configured at the force ring in such a way that deformations of the force ring, as a result of an axial force applied on the force ring, are measured. A housing lid is connected with the force ring, so that the force ring and the housing lid enclose the circuit board and the force transducer. Also provided is an external connection for picking up an electrical signal.
