Pipe metal detector DMO
The DMO type pipe metal detector is designed to detect ferrous and non-ferrous metals in loose, fibrous, liquid or pasty materials transported in pipelines with the highest precision. It is used in free fall, pneumatic and pressure transport systems. The DMO detector protects process machines against damage caused by metal contamination, prevents production downtime and ensures product quality.
The DMO metal detector is reliable, easy to use and designed for continuous operation. The metal detector is characterized by the highest sensitivity of metal detection in the entire area of the transport tunnel. The DMO detector meets the requirements of food quality management systems ISO 9001, ISO 22000, HACCP, BRC, IFS.

Principle of operation of the DMO metal detector
The tested product moves through the metal detector tunnel. The detector creates a high-frequency electromagnetic field throughout the entire transport tunnel area - no dead zones. 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.
