Abstract: A capacitive dynamometer comprises an elastic body with a measuring cavity which is deformed in different directions when a mechanical force to be measured is applied to the elastic body. Deformation of the inner wall of the cavity in different directions are picked up in the form of changes of capacity in opposite senses by means of capacitor electrodes co-operating with the inner wall. By applying these changes of capacity to a differential capacity measuring device, a signal may be obtained which is representative of the force to be measured and is not influenced by changes of temperature, because these will change the capacity values of all electrodes in the same sense.
