The METAL SHARK® GF (Gravity Feed) is used for pipelines with free-falling products to detect metal contamination in continuously flowing granulates or powders such as sugar, flour, grain or even plastic granules. The sensitive sensors detect the smallest metal contaminants, and fast-switching separation flaps discharge them directly from the product stream during ongoing production.
- Detection unit (sensor) GF incl. mounting frame
- Control unit METAL SHARK®
- Rejection unit (also avialable without reject system)
- POM pipe for detection zone incl. quick clamping rings
- Monitoring of loose, free-falling or compressed air conveyed products in pipelines
- Quality assurance for incoming goods, outgoing goods or during running production
- Machine protection, e.g. for mills or extruders
