MBA801 Halfpipe – LEVEL MEASURING DEVICE
The new and digital semi rotating paddle – the MBA801 Halfpipe – measures directly in the falling flow of bulk material. 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.
The paddle alternates below the protective cover by 120 degrees. The swiveling prevents material from becoming wrapped around the shaft or the paddle jamming and displaying incorrect messages. If the bulk material rises up in the silo and blocks the swinging paddle, then an electronic signal is emitted.
The Halfpipe is put at positions where a fill-level measurement has not been possible until now. The double sealing system protects the electronics against dust and moisture getting in, and with the ATEX certification, the level measuring devices are well equipped for zones prone to a dust explosion.
