This diaphragm level switch alerts when bins are full
The BM-25 diaphragm switch (photo) is a rugged pressure switch for high- or low-level alerts in bins containing non-hazardous, free-flowing dry materials. The BM-25 alerts operators to high or low levels or when chutes or conveyors are clogged. It is a simple and convenient way to stop overflowing product or wasting valuable material in the bottom of a bin. Suitable for bins and silos, the BM-25’s simple mechanism activates a sensitive micro-switch to indicate when material reaches the level of the switch in the bin. The pressure switch alerts when it senses high or low levels. Typically, it is wired to a light, horn or alarm panel. The switch has a silicone diaphragm and is enclosed in a nylon housing, designed to increase durability. There are models to mount internally or externally. The corrosion-free polymer construction makes the device suitable for agriculture cooperatives or any business storing dry bulk solids. It monitors the level of material like corn, soy, wheat, wood, plastic, crops, rice, powders and landscaping materials, as well as aggressive chemicals like fertilizer pellets. — BinMaster, Lincoln, Neb.
