Abstract
A bin level detector and filling switch operates in response to a pulverulent, fluent material spilling over the top of a vertically mounted tube open at both ends. The upper and lower ends of the tube correspond respectfully to the points at which the bin is to stop and start being filled. As the material fills the tube it depresses a movable plate holding a first magnet. A second magnet is oriented with respect to the first magnet with like poles opposite and is mounted outside of the vertical tube and positioned so that movement of the one magnet results in a reciprocal movement of the other magnet. The movement of the second magnet is utilized to operate a control device in response to the level of pulverulent fluent material in the bin. The control device may be an electrical switch that effects or operates the filling mechanism of the bin, an alarm device or some other satellite function.
