Follower Arm Potentiometers

MAINTAIN CONSTANT TENSION - The follower arm potentiometer is used to maintain constant tension when using a brake for producing unwind (payout) tension, or when using a clutch for rewind tension.

The arm rides on the roll, measuring the roll diameter. As the roll size decreases, the arm moves downward, rotating the potentiometer shaft. The power supply current automatically decreases, which decreases the brake (or clutch) torque to maintain constant tension.
