Detecting metallic foreign body present. With the use of metal detectors (Metal detector) for detecting foreign matter or contaminants metal (Metal) in goods and raw materials. This review process has a direct impact on the efficiency of controlling hazards at critical control points (Critical Control Point: CCP), which is critical for the application of HACCP. For example, the food industry or consumer goods industry. Clothes Tobacco due to contamination of scrap metal would result. To control manufacturing processes and equipment, including consumers or harm. Business has been contaminated by the metal. Using metal detectors to detect a casing (Contaminant) in goods. Or materials used must be chosen, and those with expertise in the acquisition. Control apparatus and a system for assessing the performance of an engine. The accurate control Sq metal must have knowledge and understanding of the principles. The machine and the control to be able to make a metal detector. Work effectively, the basic principles of metal detectors (Metal Detection - The Basic Principles) principle of operation of the metal detector (Theory Of Operation) metal detector can detect metals through. The balance of the large electromagnetic field generated by the coil to the contract. Problems with the operation of the internal metal detector. The metal detector is mainly used to create a wave of energy similar to radio frequency waves by a combination of electric and magnetic fields formed around the coil conductor. Or the balance of power, an electromagnetic field around the coil that Balanced Coil, which is a state where the electromagnetic field caused by the transmission of energy from the coil signal problems or Transmitter Coil to coil receiver or Receiver makes magnetic field. electricity generated between the two stent types was born. Electromagnetic properties of a magnet (Magnetic) or conductive properties. (Electrically Conductive) is the electromagnetic field surrounding the coil and the coil important signal receptor , thereby winding both in the right place. Right and proper in the metal detector will affect the magnetic field intensity. Electric iron that occurs in the area of metal detectors and affects their ability. Detecting metal objects The characterization of metal with properties of magnetic or electrical properties of this. It affects mainly the detection of metal contaminants in the material moving through the field. Electromagnetism, and if the contract issues that arise during the winding, two types are available. The intensity or strength of the signal sufficiently. Metal detectors will measure the problem occurs and it can be processed to make. Controlled metal detectors acknowledge the presence of metal in the object to be tested factors that affect the strength of a major contract. This happens depends on the distance between the two coils. From the placement of stents both Figure 1 and Figure 2, which are positioned coil signal problems (Transmitter coil) in the middle and a coil receiver (Receiver) is sandwiched between the two. the bottle of wire transmission problems. To determine the distance between the coils on both sides must have equal distance to curl. Wire the receiver has been promised a significant strength as the key placement of stents both types. Balanced Balanced Coil conditions or use third coil winding arrangement as indicated in Figure 1, which has a transmission problem halfway between the coils. Receiver coils on either side. The arrangement of the coils are arranged around it. Channel Tunnel, designed for object moves through a tunnel while metal detecting. The Channel Tunnel is that Aperture is a winding tunnel and the arrangement of the coils is a full-cycle system. Full loop system, called the measure a major contract from the receiver coil. This major contract to deliver the most power from the coil receiver both sides. Contract issues with the opposite direction and strength of the problems that come from both. The size of the problem is the same. As a result of the problems include a zero value or balanced conditions of contract issues left and right due to the balance of power is the problem we own. Such a situation can be compared to using scales to compare. The size of the problem at the level of the contract role of conductor (Conductive Scale) and the role of magnetic (Magnetic scale) in the picture is the state of balance between features conductor and features magnetic conditions, the balance of power (electrical. equivalent), which is comparable to the balance of the scales that measure the importance of Conductive and Magnetic these metals are moving through an electric field or a combination of conditions such as interference. By the movement of metal contamination through the Channel Tunnel interference conditions such balance to the contract. Major electricity to represent significant effect on the electrical signals caused problems to the control system. Control and detection systems to work and evaluation of the changes promised by electrical problems. Setting the detector worked as the strength of the problem set or called Sensitivity threshold to select or reject materials that can signal problems brought detects electrical interference. Metal objects that may be contaminated by the performance in practical applications to meet. Barriers that affect processing, including. The ability of the metal detector used for the packaging of aluminum foil, which has the properties of iron and can interfere with the electrical problem prevented. Metal Detection because of the impact of electromagnetic interference, the problem of aluminum foil is. Custom segmentation by type of metal metal into three groups: 1. group metals.
