20100300215 | Load Cell - A load cell includes a cylindrical ring with one end closed by a membrane configured to receive a load or force to be measured. A sensor carrier plate is arranged in a cavity formed by the ring and the membrane. The sensor carrier plate is coupled to the membrane to undergo a displacement upon deflection of the membrane. The sensor carrier plate has an inner and an outer portion and carries in the outer portion at least one sensor adapted for sensing the displacement and generating a signal based on the load or force applied to the membrane. The sensor carrier plate is movably coupled to the membrane at a location between the inner portion and the outer portion. At least one further sensor is arranged in the inner portion generating a signal changing with opposite sign with respect to the signal of the sensor. | 12-02-2010 |
