METAL SHARK GF

Features

  • 4-quadrant technology provides maximum detection performance with the highest reliability 
  • Simple setup with TeachAssistant, pre-set product types like salty, sweet, wet, dry etc.
  • Memory for up to 250 products
  • Easy to use with intuitive and multilingual menus

  • Documentation of all events and metal messages
  • IFS and HACCP reports available on the display at the simple push of a button
  • Optional: Data transfer to USB interface or connection to the company network via SHARKNET software
  • Cyclical function monitoring with Performance Validation System (PVS)

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.

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
