In production engineering, bio mechanics, general machine building, robotics etc., dynamic forces or moments are rendered capable of measurement in a plurality of components in conjunction with cyclic processes. According to the invention, thrusts are converted into moments and transmitted via tensile/compressive forces onto piezoelectric rod elements, while axial compressive/tensile forces are led directly onto the same piezoelectric rod elements. Given an appropriate arrangement of the piezoelectric rods and their signal evaluation, it is possible to construct entirely novel types of sensor and dynamometer in which the required electronics package can be directly installed in certain applications directly between the piezoelectric rod elements. However, the invention has particular advantages for the miniaturisation of multicomponent measuring arrangements. For this purpose, the electronics package must be arranged outside the sensor. Applications of such measuring arrangements are provided in multicomponent measurement of expansion force and acceleration. <IMAGE> |
