Pan 1 of the balance is connected to a Roberval mechanism 3 and the weight of load 11 is determined by a load-measuring device 4 responsive to the vertical force. Eccentric placing of the load 11 on the pan can cause errors in measurement. These are corrected by measurement of deflections of a support 12 in the horizontal plane by a sensing system 2. The device 4 can be a load cell or electronic balance. The system 2 can be capacitive or photo-electric, or may use strain gauges. The support 12 may be made more flexible to increase the sensitivity. |
