ABSTRACT:
A scale arranged and constructed of relatively small size to be hand held and portable for use in weighing relatively light articles such as fish and the like. The scale operates on a capacitance measuring concept wherein an initial capacitance between two conductive, spaced and insulated plates is measured with a change in distance between the two plates caused by a load is measured and, through a logic circuit, converted to a digital read-out. The capacitance sensor unit for the measuring of the capacitance caused by the load includes a stationary plate and a moveable plate insulated from each other with proper leads connecting the plates to the logic circuit. The entire capacitance measuring device is provided in a sandwiched arrangement to provide a small and compact unit. The logic circuitry provides for digital readout and provides automatic zeroing.
