The BRMX rotary paddle bin level indicator provides reliable point level detection and measurement of dry bulk solids in bins, tanks, silos, hoppers and conveyors for materials including grain, feed, plastic pellets, cement and aggregates. Mounted on the top or side of a bin, the BinMaster BMRX alerts operators when bins are full without the rigors and risks associated with climbing and continuously checking bins levels. When material is not in contact with the paddle, the paddle rotates freely. When the paddle comes into contact with dry bulk material, the paddle stops rotating and sends a signal – normally through the use of a horn or light – to alert that the bin is full.

The BinMaster BMRX features “de-energized” operation of the motor which shuts the motor down when materials is present, versus competitive rotaries which put the motor in a "stalled" condition. Power is not consumed until the bin is emptied and the drive shaft again begins to rotate – which saves on energy costs and prolongs motor life. It offers a fail-safe alert providing notification when power to the unit is lost. The BMRX rotary design includes a screw-top enclosure for easy access to motorized parts. It is CE approved and is appropriate for use in hazardous conditions when explosion proof protection is needed – featuring Class I, Groups C and D, Class II E, F, and G listings.
