Potentiometer Follower Application

Wiring a Laureate transmitter for a potentiometric pot follower application

In potentiometric (or potentiometer follower) applications, the signal from a sliding contact voltage divider can be converted to engineering units such as position, level or percentage. By operating in a ratiometric mode, the transmitter will remove any effects caused by variations in the excitation supply.

For use with a 1 kΩ potentiometer, the recommended applied excitation voltage is 10V. A 2 kΩ resistor should be placed in series with the excitation output and excitation return leads. This will allow the transmitter's 2V scale with a high input impedance of 1 Gohm to be used.
