Metal Detector METAL SHARK® GF

Metal Detector METAL SHARK® GF

METAL SHARK® GF metal detectors are built into gravity feed pipelines to monitor for unwanted metal contaminants in continuously flowing granules or powders, such as sugar, flour, corn meal or spices. As bulk material flows through the metal detector, the reject flaps promptly separate even the smallest metal contaminants from the product stream.

METAL SHARK®  GF (Gravity Feed) is specifically designed and constructed for the food industry and its requirements. It is enclosed in 100% stainless steel housing, product touching parts are made according to FDA food grade quality standards. The maintenance-free design and high-quality construction ensure reliable operation even next to vibrating machines, in hot or explosion-endangered areas (ATEX zone 21 and 22 versions available).

METAL SHARK® GF can log in to the SHARKNET® for documentation and reports according to HACCP, IFS, GMP and BRC.

Description

METAL SHARK® GF (Gravity Feed) was developed and designed especially for the food industry and its requirements. It is enclosed in 100% stainless steel housing for easy cleaning, product touching parts are made according to FDA food grade quality standards. It also comes with a rock-solid sensor head and mounting frame design that ensure consistent reliability and performance. The detector can be located even near vibrating machines. It boasts the industry′s shortest installation height and the mounting frame with integrated metal-free zone allows for exceptionally quick and easy installation.

Metal Detection Levels:

METAL SHARK®  GF:

  • ferrous: 0.5 – 4.6 mm
  • non-ferrous: 0.7 – 5.8 mm
  • stainless steel: 0.8 – 6.9 mm

METAL SHARK®  GF compact:

  • ferrous: 0.7 – 2.6 mm
  • non-ferrous: 1.0 – 3.2 mm
  • stainless steel: 1.1 – 4.1 mm

The detection levels strongly depend on the individual detectors construction, the products flow rate and of course the pipes diameter. For a detailed list please see the specifications.

Reject options:

  • Reject EX-S: Standard reject type for most products. Very fast switching, so it works properly even with high product speeds.
  • Reject EX-P: Standard reject for fine and powdery products, a sealing flap prohibits leakage.
  • Reject EX-K: The EX-K reject system is  similar to EX-P but with more sturdy mechanics to withstand the challenges of abrasive products and constant wear.
  • Reject EX-CB: Particularly suitable for the absolutely residue-free discharge of very fine contaminated granules and powders.
  • Reject EX-R: Specially designed for very rough products e.g. stones or gravel.
  • Reject EX-D: Standard reject for pipe systems doing the product transportation by air pressure.
  • Reject EX-A: Similar to EX-D, but holding constant pressure inside the whole pipe system while rejecting contaminated products.

For detailed information on the different rejector types see METAL SHARK GF EX types.
