It is the star product of our range of manufacturing due to its great resolution and simple installation.
It consists of a single detector coil designed to be installed under the conveyor belt. When a metallic body passes, mixed with the stone, a signal is emitted in the detector, which, once it is amplified, is transmitted to the control box that acts by stopping the conveyor belt and the feeder, while the acoustic and visual alarm is triggered, alerting on the detection.
