The bi-directional shaft tachometer system consists of two proximity sensors, a signal conditioner (STC206C) and an analog display (STC206M). The sensors detect for the scanning target (mounted on the rotating shaft of the machinery) and produce a frequency signal which is converted into a linear output signal (by the signal conditioner) and fed into the analog meter.
