A dial gauge indicator is a precision instrument used to measure small linear distances or variations. It amplifies these movements through a system of gears, displaying the results on a circular dial. For example, it can precisely determine the runout of a rotating shaft or the flatness of a machined surface.
Accurate dimensional measurement is fundamental in manufacturing, quality control, and various engineering applications. Using such an instrument allows for verification of tolerances, assessment of wear, and ensuring proper component alignment. Its history reflects a constant pursuit of improved measurement techniques across numerous industries.
