Function
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.

Accessories & Extras
The METAL SHARK® GF can be perfectly adapted to your production by various special designs and accessories. Different temperature or hygiene requirements are taken into account as well as complicated product requirements for metal detection or the environment (ATEX).
-
The SHARKNET® software connects METAL SHARK® metal detectors with a central computer, providing centralized storage of all operating data plus batch and alarm documentation for HACCP and IFS compliance.
-
BRC-Kit for a fail-safe system according to the guidelines of the British Retail Consortium with metal detection alarm, product counter, product jam monitoring, required covers, rejection system as wel as monitoring of container (container full), air pressure of the reject system and reject functionality.
-
Product temperature up to max. +120°C, with this option the sensor has protection class IP54.
-
Increase of the IP protection class by adapting the sensor seal, installing additional seals and a double housing for the control electronics.
-
Stacking lights and signal horns/sirens available in different versions and IP protection classes.
-
Version for use in potentially explosive environments possible, ATEX zone 22.
-
Reports an error if the air pressure is too low for the functionality of the reject flaps.
-
Warns if the reject flap has not switched correctly after metal detection.
-
Monitors the flaps for complete switching to the good or not good position.
-
Material for simple functional testing, consisting of an insertion flap, through which spherical test specimens can be inserted into the pipeline, and a catchment grille for the test specimen including removal flap.
-
Functional test that does not require opening the product pipelines: Test pieces (FE/NFE/VA) are moved with compressed air through a separate test tube. The control unit indicates which sphere sizes are to be tested. Incl. push button for FE, NFE and VA testing, pneumatic valve, test specimen.
-
Test balls, diameter 25 mm made of plastic POM, with embedded metal ball made of iron, brass and stainless steel, certified ball size, metal type and certificate number are embedded in the test ball.
-
Issue of a Performance Verification Certificate (proof of functionality for audits) by CASSEL service technicians, e.g. during commissioning or maintenance.
Delivery Scope
- 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
Application
- 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
