Digital measuring instruments

摘要: A digital instrument produces a continuous readout representative of the linear movement member positioned by rotatable shaft. The comprises equally spaced markings formed on an element carried bushing intended to be secured Sensing means cooperate with and produce output pulse in response passage marking past sensing means. pulses are counted reversible counter count being displayed display electronic circuitry is two printed circuit boards each which supports bearing for bushing. fixed casing fixedly means, counter, boards.
