Electronic level switch
MBA 100
SMB Group
The MBA 100 is a mechanical level detection switch for bulk material. The switching process is performed by the pressure the bulk material onto the detectors stainless steel membrane.
This actuates a micro-switch which can trigger an electrical signal. As the MBA 100 does not require any electricity, no electric supply circuits are needed when utilizing this product.
The MBA 100 is mounted either on the side of the container wall or slightly oblique. No detector parts stick into the container; the MBA 100 lines up precisely with the container wall, preventing damages and guaranteeing easy maintenance works.
Because of this, typical application areas of the MBA 100 are maximum level indications with conveyor belts, transfer stations, downpipes or bucket chain conveyors.
