The BinMaster RL level sensor is designed to provide highly reliable bin level data in challenging environments where dust levels are extremely high. The non-contact, continuous level sensor works in powders and solid materials of all types, including very low dielectric materials, which until now have been largely incompatible with non-contact devices. The acoustics-based device features a self-cleaning, non-stick surface that does not require routine maintenance or air purge for cleaning. This eliminated manual cleaning of the unit and frequent climbing of bins, which is a safety hazard. It uses acoustics-based technology at very low frequencies, allowing it to penetrate dust. The device is designed to be easy to program and simple to maintain.
