Hall effect grain level switch

摘要

A Hall effect grain level switch (10) is positioned adjacent a grain fill opening at an upper portion of a grain enclosure. A Hall-voltage (26) generator is coupled to the housing (12) in a fixed position. An elongate member (14) is pivotably coupled to the housing with the magnet (24) being mounted adjacent a proximal end of the elongate member (14). A grain contact member (16) is coupled adjacent a distal end of the elongate member. The Hall-voltage generator (26) and magnet 824) are positioned adjacent each other to provide a first output signal state when the elongate member extends vertically in a rest position. The Hall-voltage generator and magnet are distanced from each other to provide a second output signal state when the elongate member is pivoted to a non-vertical switched position in response to grain moving the contact member (16).
