THE EMCAM

The sensor makes the difference

The “electromagnetic camera “, EMCAM for short, is an intelligent sensor system for use in dry metal sorting. It is the result of the rigorous implementation of new methods and technologies




Operation principle

All sensor-based sorting machines operate according to the same principle:

The input material is transported on a conveyor belt along a sensor and the recognised particles are extracted with compressed-air nozzles.


The challenge

The sensor plays a decisive role for throughputs and sorting quality.

Such a system must be capable of continually analysing the passing material flow, recognising and differentiating between even the smallest objects located close together within it, exactly estimating the material, form, position and speed of these objects and initiating their removal in a time correct and location specific fashion.


The EMCAM

With the "electromagnetic camera" we use a new kind of operating principle in sensor-based sorting - magnet induction tomography.

The EMCAM differs fundamentally from all other conventional metal detectors. Without a central sorting computer and optical means, irrespective of surface corrosion, coating and humidity of the bulk solids, the EMCAM is able to find and flawlessly differentiate between non-ferrous metals, stainless steel and magnetisable material.


The electromagnetic camera

  • generates an electronmagnetic field in which it registers changes using gradiometers of a particular design
  • identifies the material according to its magnetic and electric conductivity with an integrated, highly specialised computing technique
  • continuously determines the exact position and velocity of the particles and passes on extraction orders directly to the compressed-air nozzles
