Abstract: A device for indicating the weight of an object is disclosed herein and includes a first circuit for producing an oscillatory excitation signal which is capacitively coupled to a second circuit for producing at the output of said second circuit a signal indicative of the weight of said object. In this regard, the second circuit is capacitively coupled to the first circuit by a coupling plate mounted to a support member for movement in response to the weight of said object. This output signal is applied to an electromagnetic assembly which, in response thereto, applies to said coupling plate a proportional force which is equal and opposite to the gravitational force of the supported object for terminating movement of said coupling plate. In this manner, the output signal may be monitored for indicating the weight of said object.
