Plate metal detector DMP
The DMP type plate metal detector is designed to detect ferrous and non-ferrous metals in piece goods or bulk materials up to 200 mm high. The DMP detector protects process machines against damage caused by metal contamination, prevents production downtime and ensures product quality. It is also used as an additional level of protection after the magnetic separator.
The DMP metal detector is reliable, easy to use and designed for continuous operation. The DMP detector is characterized by high metal detection sensitivity, but its precision decreases with the distance from its surface. The metal detector's design allows for simple integration with an existing production line and conveyor system.

Principle of operation of the DMD metal detector
The tested product (bulk or bulk) transported on a belt conveyor moves over the detector installed under the belt. The detector creates a high-frequency electromagnetic field that covers the entire width of the conveyor belt. The electromagnetic field generated by the transmitting coil induces a certain signal in the receiving coil. The metal contained in the product deforms the electromagnetic field lines generated by the transmitting coil, thereby changing the amplitude and phase of the signal induced in the receiving coil. The received signal is analyzed by the detector's electronic system and converted into a metal detection signal. The metal detector detects iron and its alloys, including stainless steel and acid-resistant steel, and non-ferrous metals such as aluminium, copper, brass, zinc, lead, silver, etc.
