The BM-25 bin level indicator provides a new way to manage materials in bins or silos. It 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.BinMaster eliminates the need to stop and ask, “Is a bin full yet?” Ideal 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.
