Metal detector for plates and webs


  • Detects metal contaminants in plates and webs
  • Precise metal detection with multi-segment sensor saves valuable material
  • Highest sensitivity through 4-quadrant technology
  • Intuitive control and easy setup with autocalibration and Teach Assistant
  • Maintenance-free through automatic balance and calibration control




The METAL SHARK® COMBI TU is a multi-segment sensor typically used over fabric, non-woven or paper webs as well as plates of different materials. It detects the smallest metal particles from 0.6 mm and localizes their position in defined segments of the product.

The METAL SHARK® COMBI TU is suitable for widths up to

5 m/16.6 ft and more available. It can be easily operated in humid environments with ambient temperatures from -10˚C to +40˚C and product temperatures up to 65°C.


Digital signal processor, digital frequency generation, digital balance control, automatic calibration, digital noise filters, integrated flexible control functions

IP 65, optional IP66 or IP67
standard: -10° C up to +40° C, rel. humidity 30% to 80% (non-condensing)
option: down to -40° C or up to +55° C
Product temperature
standard: -30° C up to +40° C
optional: -40° C or up to +60° C
Power Supply
1 phase 110-240 VAC, 50/60 Hz, 20 W typ. (60 W max.)
RS232, LAN (optional, for SHARKNET), USB (optional)
Maintenance-free, sensors calibrate themselves
integrated diagnostic software, automatic self-test
Inspection widths
1,000 mm to 5,000 mm (standard), up to 7,000 mm (optional)
Aperture height
28 mm net
The maximum panel thickness of the product depends on the thickness of the product and the deflection, the sum of which must not exceed the net passage height. Example: Net passage height 28 mm – panel thickness 8 mm = max. 20 mm panel deflection
FE 0.6 mm, Al 0.8 mm, SS 0.7 mm
(The sensitivities are highly dependent on the environment in which a metal detector is installed. The sensitivities mentioned here should therefore only be considered as guide values).

Accessories & Extras

The METAL SHARK® COMBI TU can be perfectly adapted to your production by various special designs and accessories. Various temperature requirements are taken into account as well as complicated product requirements for metal detection.

The SHARKNET® software connects METAL SHARK® metal detectors to a central computer and offers central storage of all operating data as well as batch and alarm documentation for HACCP and IFS conformity.
Signal transfer of belt speed and mat height from the system control for automatic adjustment of the detector sensitivity.
Temperature extension cold
Temperature range extended to -40°C, cold-elastic grouting material, insulation, switch cabinet heating and other measures.
Temperature extension hot
Temperature range extended to +55° C, adaptation of control cabinet, additional thermal insulation, replacement of filter fan, heat exchanger and/or active cooling units.
High temperature extension for product
Product temperature up to max. +120°C, with this option, the sensor has protection class IP54.
