The Diaphragm will detect and activate a switch when grain level is present. It is built to mount on the inside of a bin wall. The diaphragm is perpendicular to the bin wall to minimize wear on the diaphragm due to spreading grain. It is also built with the diaphragm tilted down to decrease wear on it and also to prevent a buildup of material from activating it. Two small air holes are in the bottom of the housing to allow air movement in and out of the diaphragm area. It is critical that these holes remain open for proper operation at all temperature extremes and air pressures.
