摘要: A flat scale indicating device for use with servo units having feedback loops, having an indicator arm pivotally mounted to a sector gear, the latter being in meshing engagement with a rotary pinion for transmitting rotary motion of the pinion to a straight line translatory motion at the pointer end of the indicating arm. The indicator arm further functions as a potentiometer wiper and an electrical connection is provided between the arm and a suitable amplifier bridge circuit.
