Abstract: A force measuring apparatus comprises a steel base body and a bending element joined thereto. The bending element comprises a composite of at least first and second layers. The first layer is comprised of steel and is welded to the base body. The second layer is comprised of a hard material which is harder than the steel material of the first layer. The second layer includes a section of reduced thickness defining a bending region to which a deformation sensor is attached to sense deformations of said bending region in response to the application of the force being sensed.
