AdvaCon

AdvaCon continuously monitors structure-borne sound up to 100 kHz and is hence capable of highly selective and sensitive refi ner plate protection and health monitoring of other rotating equipment, such as motors and gears. Multiple, high-resolution acceleration sensors installed at standardized locations replace complex and manual measurements. The equipment’s condition is continuously monitored, and measurements are available for operation and maintenance to ensure optimum and safe operation while providing key information for planning shutdowns and repairs. AdvaCon is also used for dynamic zeroing of plates in single-disc refiners as well as in conical-disc machines for both flat and conical zones.

Automatic refiner plate protection and condition monitoring

AdvaCon avoids plate clashes by continuously monitoring acceleration amplitude within a specific and adjustable frequency range relating to
refiner plates. When AdvaCon senses a sudden signal increase above the moving average (accounting for plate wear), it immediately sends a digital signal to open refiner plates and avoid a catastrophic failure.
