Metal detectors principle: the use of alternating current through the coil, resulting in a rapidly changing magnetic field. The magnetic field inside the metal object can be an eddy current can be induced. Eddy current will produce a magnetic field, the magnetic field affect the original upside down, causing the detector beeps. Accuracy and reliability depends on the stability of the metal detector frequency electromagnetic launchers, general use from 80 to 800 kHz operating frequency. The lower the frequency, the better the detection performance of iron; the higher the frequency, the better the performance of the detection of high carbon steel. Food metal detector sensitivity of the detector increases with the decrease of the detection range, the sensor signal depends on the metal particle size and conductive properties.
Good mechanical manufacturing process: stainless steel probe and rack, a variety of protection class choices for customers, adapt to a variety of production environments conveyor anti-deviation design: the use of special anti-deviation conveyor design, effectively prevent rich belt deviation The peripheral interface (optional): You can configure the RS-485 data communication, PLC programming node, printer output, can provide real-time data for the production management system for remote control, analysis and monitoring, provide valuable retrospective information
