The Paddle Indicator is rugged and sensitive in operation, and can be mounted sideways on a hopper or silo for low and high level indication.  The paddle is stopped when material level reaches it.  When the paddle is stalled the motor continues to rotate until a micro-switch is actuated.  The micro-switch can be used to control numerous functions such as lights, alarms and stopping or starting conveyors or other feeding systems.  On material dropping away from the paddle the micro-switch is released by a spring and the paddle starts to turn again.  A flexible section of shaft isolates the paddle against shock loading.   The shaft seal is designed to eliminate the entry of moisture and dust from the hopper.
