tapped holes 10 of the load receiver 9 the load receiver 9 is moved vertically downward in relation to a stationary part 11 shown in the right hand part of the drawing of the deformable body 1 which is fastened directly to a housing or to an intermediate mounting bracket as the bending zones 2 3 4 and 5 undergo a deformation this deformation is measured by means of strain gauges 13 that are adhesively bonded to the top side 12 of the deformable body 1 at the bending zones 2 and 4 the strain gauges 13 have a strain sensitive resistor track 14 which can be arranged in the shape of a meandering pattern on a carrier substrate 15 the resistor track 14 is connected to connector electrodes 17 through which the resistor track 14 is tied into the sensor bridge circuit not shown here the carrier substrate 14 includes or consists of a polyimide foil with a thickness of between 10 and 30 microns strain gauges 13 can be arranged not only at the bending zones 2 4 on the top side 12 of the deformable body 1 but also at the bending zones on the bottom side of the deformable body 1 which is not visible in the drawing the strain gauges 13 can be bonded to the deformable body 1 through an adhesive layer 16 the adhesive layer 16 includes.
