Dwyer Series DBLM "Mini-Bin" Dry Bulk Level Monitor provides reliable level sensing for dry bulk solids in tight spaces. Its compact size makes it ideal for replacing standard rotary paddle monitors. It uses a 1 rpm motor to rotate a paddle and detects material presence by monitoring motor strain. The SPDT snap switch output can be used for equipment control or alarms. Suitable for materials weighing 25-65 lbs/cubic foot, it mounts on bin sides and has a NEMA 1-rated polycarbonate housing. Installation accessories like mounting flanges and reducers are available.
