2. GRAVITY POSITION INDICATORS
Gravity position indicators with analogue and digital-analogue readings
Suitable for use on control spindles with horizontal or max 60° inclined position. The movement is housed in a sealed case (fig. 1). It consists of a counterweight system, fitted on a precision ballrace, which rotates on a central spindle integral with the indicator case, fitted on the handwheel/knob. At the end of the spindle there is a red pointer, which rotates with the handwheel/knob. A series of gears with different ratios transmits the rotation of the spindle to a black pointer.
On the counterweight, a graduated dial is also fixed. If the indicator is fitted on spindles with horizontal position (or max 60° inclined) the dial is kept still by the gravity force and the pointers rotate over it when the handwheel/knob turns.
