DEFINITION

Classification: 73/862.59

By measuring vibrations (e.g., resonant frequency):

Subject matter under subclasses 862.381+ wherein the sensing means comprises a stressed vibratory member that produces a mechanical oscillation having a frequency or amplitude that is indicative of the applied force.

(1) Note. Usually, the applied force changes the resonant frequency of the member and the frequency is measured electrically.
