RotoLine Geared Potentiometers
How it works
| Geared potentiometers are used to track absolute position by way of voltage/current or resistance output.
A connected SIKO display or PLC1 will output a position value based on the amount of voltage it receives from the geared potentiometer. 1 The display or PLC must be able to receive analog signals |
An internal system of gears inside the device connects to an integrated 1- or 10-turn potentiometer.
At the beginning of the turn cycle, the potentiometer will allow no voltage to pass through it. As its shaft turns, the potentiometer will allow more voltage to pass through to the display. The purpose of the internal gear system is to spread the single turn (or ten turns) of the potentiometer over many shaft turns.2 2 For example, in a 30-turn application, a gear ratio of 30 could be used with a 1-turn potentiometer. For the same results, a gear ratio of 3 could be used with a 10-turn potentiometer (3 x 10 = 30) |
