Abstract
This invention relates to a capacity measuring device. A first capacity-frequency converter operates on the capacity to be measured and supplies a measurement frequency FM; a second capacity-frequency converter co-operates with a standard capacity and supplies a standard frequency FE. A calculation circuit determines (M.multidot.FM/FE)-N and a display circuit visualizes this numerical magnitude. The device can be used for weighing apparatus.
