Circular-aperture metal detectors are installed in tube conveyors, where they serve to reliably detect magnetic and non-magnetic metals in raw fiber material. By eliminating metal particles, the metal detectors protect equipment from damage, reduce production downtime and prevent sparking.

Circular-aperture RZ tunnel metal detectors are used mainly in high-precision applications. The enclosed-aperture design ensures very high metal sensitivity throughout the tunnel area. RZ coil technology means that a metal-free zone is not required in the installation area.
