The SE3 series level switch’s paddle actuating mechanism is attached to the shaft inside the bin or hopper that the SE3 series is mounted on. A clutch mechanism is also a key component within the SE3 level switch assembly. With the target material not present at the paddle inside the bin, the paddle will rotate freely and the internal switch output will be in its starting position and the internal LED will illuminate Green indicating that the paddle is rotating free of material. When material is in contact with and covering the paddle inside the bin or hopper, the clutch will disengage, the switch output changes state, the motor power is disconnected internally and the Red LED illuminates indicating material presence. The SE3 series compact rotary paddle point level sensor is cost-effective and is the ideal bulk solids level switch for installations with limited space surrounding the mounting point.
