The EGE 3000 metal detector system protects conveyor belts, for example in jaw crushers or in the cleaning of building rubble, from damage caused by medium and large metal parts contained in the bulk material. The MA 125 connection box now makes it possible to connect two coils to one amplifier at the same time. This means that the conveyor belt can also be monitored where a single coil may not be sufficient to reliably detect metal parts. The double coil system can be adapted to the specific conditions of the system on site: The coils can be arranged next to each other, on top of each other or in a V-shape. The connection box is designed for ambient temperatures between -25 °C and +70 °C and offers IP67 protection. The aluminum housing with dimensions of 52 mm × 113 mm is equipped with a C16 plug connection.
