METAL SHARK® GF compact

  • Reliably detects metals in free-falling goods even with limited space
  • Simple assembly due to mounting frame and quick release rings
  • Highest sensitivity with 4-quadrant technology
  • Autocalibration and TeachAssistant for intuitive control and easy setup
  • Maintenance-free through automatic balance and calibration control
  • BRC-Kit option: Conformity with the Global Standard of the British Retail Consortium (BRC) for food safety

Features

Installation Metalldetektor METAL SHARK GF für freifallende Produkte

Function

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.

Accessories & Extras

Der METAL SHARK® GF compact 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).

SHARKNET®
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
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
High temperature extension for product
Product temperature up to max. +120°C, with this option sensor#s enclosure rating is IP54
LPW/HPW
Increase of the IP protection class by adapting the sensor seal, installing additional seals and a double housing for the control electronics
Signalling devices (optical/acoustic)
Stacking lights and signal horns/sirens available in different versions and IP protection classes
ATEX
Detector version for use in potentially explosive environments possible, ATEX zone 22
Air pressure monitoring
Reports an error if the air pressure is too low for the functionality of the reject flaps.
Reject monitoring
Warns if the reject flap has not switched correctly after metal detection.
Reject position monitoring
Monitors the flaps for complete switching to the good or not good position.
Check & Catch
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.
Autotest
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
Test balls, diameter 10 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
Performance Verification Cerficate
Creation of a Performance Verification Certificate (proof of functionality for audits) by CASSEL service technicians, e.g. during commissioning or maintenance possible
