The new MOLOSbob LF20 from MOLLET is the best solution for an easy and reliable continuous level measurement of bulk solids in silos and bunkers up to a maximum measurement distance of 42 meters. Simple installation and an error-free operation although in case of changing bulk materials or process conditions characterize this measurement device that can be used for process temperatures up to 150 °C. MOLOSbob, the compact and robust measurement device with a tape made of stainless steel supplies accurate measurement results unaffected by bulk goods characteristics like dust, moisture, conductivity or grain size. This measuring device with low weight is although suitable for the use in dust explosive areas of category 1/2D. Furthermore the newly developed safety circuit avoids the run down of the sensing weight into the silo outlet area. Special designed tape wiper avoids pollution of internal housing.
