ABSTRACT:
A method for measuring the amplitude of mechanical vibrations comprises the application of a measuring sign in the form of a measuring circle to the surface of the vibrating object, the radius of said measuring circle being of any length selected out of the range of measured values. Each measuring sign vibrating jointly with the object forms a figure of its own and the vibration amplitude of the object is measured along the radius of that particular measuring circle whose visually percepted parts are in contact in the center of the figure formed by said circle.
