It is common practice to utilize a conveyor metal detector throughout the manufacturing of consumables, pharmaceuticals, personal care products, textiles, and so on to check for the presence of any stray metal particles. It is based on the principle of installing three coils in a probe, one of which is the central transmitting coil and the other two are equivalent receiving coils. The high-frequency magnetic field from the oscillator is connected to the two receiving coils through the central transmitting coil, but with opposite polarity.
When the magnetic field is not interfered with by the outside world, the voltage output signals generated by them cancel each other out. Once the metallic impurities enter this magnetic field, this balance is broken and the induced voltages of these two receiving coils cannot be canceled. The induced voltage that is not canceled out will be amplified by the control system, producing an eddy current effect and thus an alarm signal (detection of metallic contamination). An automatic rejection mechanism, etc., can be activated by the system in response to the warning signal, ensuring that any metal impurities are removed from the manufacturing process.
(2) Can detect magnetic and non-magnetic metal impurities, even if the metal is sealed in the product so that it can protect downstream equipment, reduce downtime, protect product quality, and recover investment costs in the shortest time;
(3) The small non-metallic area of the detection head minimizes the length of the conveyor belt, making the conveyor body shorter and smaller;
(4) Stability: It has high stability. The coil is completely glued inside, which can effectively prevent the spread of electromagnetic waves and reduce the possibility of false alarms caused by the movement of external metal parts;
(5) sensitivity: Special design maximizes metal detection sensitivity.
Conveyor metal detector systems are commonly used in the pharmaceutical and food industries, they can easily check for any metallic material in the product that should not be present in the food and medicine products. And their unique size advantages, ultra-high stability, and sensitivity make them easily the ideal detection solution for any application.
