The METAL SHARK® IN Liquid is developed for liquid and pasty products. With its maintenance-free design and high-quality, hygienic construction, the metal detector is ideal for reliable use in the food industry.

METAL SHARK® IN Liquid can be easily integrated into all common piping systems for pumps, vacuum fillers or even sausage meat filling plants.
Three different valve models, optimally adapted to the respective product, guarantee a safe discharge of metallic contaminants.

Accessories & Extras

The CASSEL In Liquid can be supplied with three different reject valves for different product requirements. The pressure hose or product tube are also individually adapted to the requirements of your production. Signalling devices are available as well as adapted frame constructions.

In many cases, the CASSEL metal detector is also a critical control point. It is therefore important to check that the detector is working properly at regular intervals. For this purpose we offer the appropriate testing accessories or extended functions.

  • 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 sensor#s enclosure rating is 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.
  • Detector 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 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.
  • Creation of a Performance Verification Certificate (proof of functionality for audits) by CASSEL service technicians, e.g. during commissioning or maintenance possible.
