ABSTRACT:
A mechanical force to electrical signal transducer includes a flexible metal body operable as a beam in which a bending strain is to be measured as a measure of a mechanical force. At least a part of one surface of the metal body includes an electrical insulating material with a resistance element formed from a layer of a thick film resistor ink of the type used for thick film integrated circuits fused upon the electrical insulating material. A plurality of such transducers may be combined in a weighing scale, with the individual transducers electrically interconnected to provide for electrical summing of the transducer signals to provide a total weight measurement.
