Abstract
A force sensor with two force input elements to which the force to be measured and the support force are applied. The two force input elements are substantially rotationally symmetrical and are axially spaced apart, and the force to be measured and the support force are applied in a radial direction. A spring element, arranged axially between the two force input elements connects these elements and its load-dependent deformation is converted into an electrical signal. A substantially tubular cover connected to one of the two force input elements surrounds the spring element. The cover surrounds a portion of the other force input element, forming a circumferential gap. The cover has an inwardly projecting constriction that is spaced apart by a small axial distance from an opposite shoulder on the other force input element.
