Level limit measurement VN4020 in filterdust

The Challenge

A company near Moscow supplies aluminium alloys made from recycled aluminium (bins, broken aluminium, cinder from the first production). In the exit of the furnance, gases with chalk powder are cleaned which is filtered and filled in a big bag afterwards.

Our Solution

The vibrating level limit switch VIBRANIVO VN4020 is the best solution for this application. It was installed in the tube of the big bag as full detector. The aggressive chalk powder cannot damage the stainless steel extension (316L) and the whole unit is absolutely dense. The process temperature starts from -40° up to +150°C which is an important attribute in the Russian market. As a result, the great cost-/performance ratio convinces all of our customers.
