METAL SHARK® GF (Gravity Feed) is used for pipelines with free-falling products to detect metal contaminations in continuously flowing granulates or powders such as sugar, flour, grain or spices. The sensitive sensors detect even the smallest metal contaminants, and fast-switching separation flaps remove them directly from the product stream during ongoing production.
- Detection unit (sensor) GF compact incl. mounting frame
- Control unit METAL SHARK®
- Reject unit, choose from one of seven different reject versions for different applications (also possible without reject unit)
- Pipe piece for metal-free 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 extruder
