Workings of Food Metal Detector! Are you planning to buy some metal detecting systems for your some product manufacturing unit? But before making a purchase you want to understand the Workings of a Metal Detector? This blog seeks to enlighten the readers about the workings of Metal Detectors. A Metal Detector as the name suggests is used to detect metals in the components. The most common type of Metal Detector is “balanced coil search head, ” Metal Detector. These detectors very easily detect the presence of Ferrous, Non-ferrous and Stainless Steel metal pieces. “Ferrous In Foil search head” type Metal Detectors are the most uncommon type. One can gain some understanding of how Metal Detector works, by understanding the composition of Metal Detector, which is given below: Search Head: This is the aperture from where the products pass. User Interface or Control Panel: This section is used for adjusting the machine sensitivity. Transport System: It moves the products in the detector. Reject system: It displaces the contaminated products from the line of products. How Food Metal Detector Work? • Metal Detectors use high-frequency electric current and create magnetic field. The effect is achieved with the aid of three coils. • The central coil is infused with high energy and creates a magnetic field. The coils on the sides work as receivers. • Every time a product traversing the field is suspected of contamination, a disturbance is generated and which eventually changes the receivers’ voltage. • The machines process the voltage fluctuations and the reject mechanism follows. One can also set the level of sensitivity of the metal detecting system to decide how large and small pieces of metal the machine should detect. Hope the write-up would guide you in making a wise Metal Detector purchase decision.
