BM-25 diaphragm switch This BinMaster product alerts operators to high or low levels in bins or silos containing non-hazardous, free-flowing dry materials, including plastics and powders. The BM-25's simple mechanism activates a sensitive micro-switch to indicate when material reaches the level of the switch in the bin or when chutes or conveyors are clogged. 

What’s new? The switch’s nylon housing. Previous lines are made of die-cast aluminum. The new material makes the product more affordable, but still allows it to hold up to temperature extremes and other operational rigors.  

Benefits Made with corrosion-free polymer, this device promotes worker safety by keeping staff from climbing ladders to check bin levels.
