 | 9803.001 - 5 digit mecha-opto DIGITAKER 9803.001 is a microcomputer based digital tachometer with quartz crystal oscillator to maintain high accuracy. It has a mechanical contact assembly at the top of the unit and an integrated infrared trasmitter and receiver at the base of the unit. The 5-digit LED automatically inverts when switched from contact to optical so that the display is alwasys the right way up when viewed. For optical reading, a reflective adhesive tab is applied on the rotating part DIGITAKER has a measuring range from 0.2 to 100'000 r.p.m. with automatic decimal point selection in order to ensure the better reading accuracy degree. TOTALIZING function allows to count the incoming pulses. A calibrated rubber wheel is provided for linear speed measurement directly in m/min or feet/min.
