A tunnel metal detector machine for industrial use is a highly sensitive and reliable system designed to detect metal contaminants in various products and materials transported through a conveyor belt system. The machine is typically installed in a tunnel-like structure, where the conveyor belt system passes through it, and the metal detector head generates an electromagnetic field to detect metal particles present in the product.
This machine is widely used in the food, pharmaceutical, and manufacturing industries to ensure product quality and safety. It can detect and reject metallic contaminants such as broken machinery parts, screws, nails, and other ferrous and non-ferrous metals. The machine has a high sensitivity level, and it is capable of detecting metal particles as small as 0.2mm in diameter.
Tunnel metal detector machines for industrial use are equipped with advanced software that allows operators to adjust the machine's sensitivity, noise levels, and other parameters. They also have a reject mechanism that automatically removes contaminated products from the production line. Overall, this machine is an essential tool for ensuring product quality and safety in industrial settings.
Applications of metal detectors: Quarries, Lime works, Clinker works, Sand pits, Cement factories, Slag processing, Building material recycling, Brickworks, Coal-burning power stations.
•Digital signal processing:Every data is controlled by Microprocessor. Signal processing is fulfilled by the digital circuit which is easy for adjustment, stable and reliable. To stop mistaking in transmission & reception in advance, the detector handles many operations. Easy to adjust the detecting parameters.
Detection signal shall be sent out when metal signal is detected, and then the elimination device shall eliminate the object with metal impurities or send out sound-light alarm stop signal.
Has the function of one-line signal display. When metal substance is passing through, the signal level indicator shall display different induction intensity according to the size of metal.•
Product memory:Memory function for registering various products (Max. 12 Items).Each product information is input in advance for detecting many kinds of product. Then operator can inspect every kinds of products if operator loads each product information.
•High immunity against vibration & product metal effect:Operator can check if the detector cope with product character and if the detector detect smoothly without mis-operating caused by great impact or vibration.
•Chinese & English operating menu:LCD Display is showed in English and Chinese. It is easy to interface between multinational person and detector.
•Extremely simple to install.The probe consists of 2 probe panels, one fitted under the belt and the other above the belt by means of spacers. It is quick and easy to install at the conveyor belt.
•Iron oxide and ore are ignored
•Both ferrous and non-ferrous metals are detected
•Automatic self-monitoring
•Probe and amplifier solidly built for immunity to vibration and therefore resistant to weather, dirt and impact of stones
•The sensitivity determines the minimum size of metal parts which can be detected. Depending on the individual model and the sensitivity setting, metal parts down to the size of M10 nuts or the size of excavator teeth are detectable.
•The unit can be integrated into an existing plant control system without any extra components. An On and Off button and a contactor for the conveyor belt motor are generally present. The output relay for the metal signal can be switched between normally relaxed and normally activated mode. On request an extended terminal strip can be supplied, which permits direct connection of a flashing warning light, an alarm horn or a marking device.
