Reliable Point Level Detection for Coffee Filling–with the UWT Sensor
Process reliability with varying bulk materials, no need for recalibration. Vibranivo® VN 4020 vibrating level switch: high flexibility and reliable performance A production facility for coffee and cocoa products was looking for a reliable solution for point level detection during manufacturing and packaging.
The particular challenge was that various products such as instant coffee, chicory, and cocoa were used alternately, each with different material properties. Despite this variety, the sensor needed to operate consistently and precisely, without the need for recalibration.
The Challenge
The product range included various materials such as roasted coffee beans, ground coffee, instant coffee, chicory, and cocoa. Instant coffee, in particular, may contain sugar and milk powder, depending on the variety, which creates a particularly sticky substance during mixing - a real challenge for level measurement technology.
In the packaging line, a solution was needed that ensured reliable point level detection even with frequently changing bulk materials while also meeting strict hygiene requirements.
