DEFINITION

Classification: 73/862.337

Capacitance sensor:

Subject matter under 862.325 wherein the sensing means is responsive to a change in a property of an electric nonconductor that permits the storage of energy as a result of the displacement when opposite surfaces of the nonconductor are maintained at a different potential.
