Motorized Potentiometer

The Motorized Potentiometer is used in Control Systems to apply a command variable to automatic control equipment in the form of a variable reference input or set point signal. The unit can be operated remotely with the aid of push buttons. Two push buttons are used, one for "Run-up" and the other for "Run-down". Run-up and run-down times can be different depending on the application and can also be adjusted by means of the control knobs located on the front plate.
Description:
The motorized potentiometer consists of basically a geared servo motor and a 10 turn potentiometer. These potentiometers have many special features like high resolution and linearity, reliable terminations, smooth performance, and long life. The motor and the potentiometer are coupled with suitable high precision gears. Limit switches are provided to cut off motor supply when the potentiometer wiper arm reaches either ends. By selecting different gear boxes for the motors, it is possible to have different run-up & down times setting varying from 10 to 300 sec. Single turn 1K, 1W potentiometers mounted with control knobs on the front plate are for varying the speed, one for run-up and another for run-down.
