Positive drive indicators with analogue and digital-analogue readings

Suitable for use on control spindles in any position. The movement is housed in a sealed case (fig. 1). The handwheel/knob, containing the indicator, is coupled to the control spindle. On the rear of the handwheel/knob, a flange with internal crown gear wheel (shrouded) is fitted to the machine frame by means of an anchor pin (or similar). By so doing, during handwheel rotation, the flange is integral with the machine. The rotation of the handwheel causes the planet pinion to rotate, transmitting in this way the movement inside the indicator case.

The rotation is then transmitted to both pointers by means of a gearing, while the graduated dial remains still, thanks to the fixing to the machine frame, by means of the anchor pin.
