Plastic Granule Hopper Monitoring
Mounted on the side of plastic hoppers, the sensor can detect the fill level of granules or pellets without needing direct contact, even through the container wall. Sensitivity tuning ensures accuracy despite dust or surface buildup.
Cardboard or Paper Stack Detection
Positioned along conveyor lines, the sensor identifies stacks of paper or cardboard—ideal for packaging and printing lines—ensuring proper alignment and presence before further processing.
Liquid Level Detection in Plastic Tanks
Installed externally on plastic or glass tanks, this sensor detects water, oil, or chemical levels without immersion. Its high ingress protection makes it ideal for clean-in-place (CIP) environments.
Feed and Grain Monitoring in Silos
Applied in agricultural setups, the sensor tracks the presence of dry grains, feed, or seed levels through storage bin walls, maintaining reliable readings despite dusty or changing environmental conditions.
Part Presence in Assembly Lines
Used in automated production systems, the sensor verifies the presence of non-metallic parts like plastic caps, bottles, or tablets, helping ensure process continuity and quality control.
Wood Panel Detection in Sawmills
Senses wood sheets or planks moving along conveyors. Its ability to detect low-dielectric materials ensures accurate presence detection even when surfaces are irregular or dusty.
Clear Bottle Fill-Level Inspection
Deployed in beverage or cosmetic production lines, the sensor accurately identifies liquid levels inside transparent containers without being affected by their clarity or container shape.
Powder Flow Monitoring in Dosing Systems
In pharmaceutical or chemical environments, the sensor monitors the dispensing of fine powders by detecting their presence through container walls, even in electrically noisy areas.
