ABSTRACT:
A method of and apparatus for measuring a tension by the steps of vibrating a measured object of a line- or belt-shaped configuration by the flow of air from an air nozzle so that the measured object is resonated, counting the number of vibrations of the measured object per second by the radiation of a laser light emitted from a very small distance measuring device, and calculating a resonance frequency of the measured object from the number of the vibrations to thereby obtain a tension of the measured object.
