Paddle Level Indicator

Detects and ProtectsPaddle level Indicator

The Paddle Level Indicator is designed to signal the presence, or absence, of bulk materials such as chemicals, chips, granules and powders. It is ideal for bunkers, hoppers and silos as well as for blockage detectors in conveyor chutes. A rotating paddle achieves the detection of the material.

If material impedes the rotation of the paddle, the control signal changes and the motor circuit switches off. In this state all moving parts are stationary.
