Abstract
An actuator is designed to control airflow in HVAC systems by opening and closing a damper. A slippage detector may be secured to a damper shaft to measure movement of the damper shaft. This measured movement may be compared to the expected movement of the damper shaft as indicated by the movement of a rotatable output of the actuator.
