Rotary paddle level limit switch MBA801

for bulk materialsfor adhesive materialsfor powders

Thanks to the new product series semi rotating paddle MBA801 with a halfpipe, the modern level measuring devices with stepper motor technology can now be used for even more special applications in bulk materials. The paddle in the MBA801 Halfpipe is directed downwards by 90° and is therefore ideally suited for horizontal, i.e. lateral, installation in silos. As a result the Halfpipe is put at positions where a fill-level measurement has not been possible until now. As the shaft and paddle are completely protected from falling bulk material under the roof, the MBA801 Halfpipe can also be used in the bulk material flow – the falling bulk material does not influence the measurement. Benefits • UNIVERSAL USE The device offers maximum application versatility, regardless of the bulk material properties • STEPPER MOTOR DRIVE Direct drive without gearbox, return spring or leaf spring; magnetic clutch is a functional component of the stepper motor, electronic and configurable torque • INDIVIDUALIZATION Switching behavior, speed and swivel range of 120° can be adjusted as parameter sets; sensitivity of the device is separately adjustable • USER FRIENDLINESS Simple assembly; robust mechanics; independent of application conditions; adjustable application levels (parameter sets) • HALFPIPE AS A FIRMLY WELDED PROTECTIVE ROOF 12 mm shaft with welded paddle; protective roof directly above the shaft; double seal to the process connection; only 90 mm opening to the silo BACKGROUND The extra-strong shaft (12 mm shaft diameter) is mounted on a firmly welded paddle under a protective cover thereby making is perfectly protected against heavy or abrasive bulk material.
