Belt

Tunnel for Conveyor Installation on Bottom and Top of the Conveyed Material

Typically, the Metal Detector TU types are used in:

  • Plastic recycling
  • Rubber production
  • Wood and paper processing
  • Food related industries

The control box can be wall mounted or attached to the sensor.

No belt cut: The TU type has a divisible sensor head. This makes installation into an existing conveyor exceptionally easy. Sensor head can be installed without splitting the conveyor belt.

Aperture height: The aperture height can be changed later on. The TU automatically calibrates certain changes in the sensor head geometry.

Documentation and Traceability
Metal detectors are considered a critical control point, and continuous checking is required to meet standards. Cassel metal detectors can be programmed to automatically remind the operator to test equipment performance at pre-set intervals. A list of metal contaminant detections, changes in parameter settings, etc., is stored with both date and time. This list can be viewed on screen or the data can be downloaded to a Windows-based PC.
  • Performance validation system (PVS) automatically prompts operator to test Metal Detector performance at pre-set intervals
  • Operational history: events are recorded with the date and time and can be viewed on the control panel or export the log via a serial port
  • Data will not be lost during a power outage
