The basic principle of metal detectors (Metal Detection-The Basic Principles).Principles of the theory of operation of metal detectors (Theory Of Operation).A metal detector that can detect metal. The principle of balancing contract yotnam arising from electromagnetic coil delivery contract. Or are the thousands inside the metal detectors. Metal detectors will be used to generate energy that is similar to wave. By radio frequency, creating a balance of electromagnetic fields that occur around the coils of conductive or call the equilibrium of energy-electrical magnetic field around the coil, this Balanced Coil, which is a State that electromagnetic fields caused by wave energy from the coil sends. Headquarters contracts or Transmitter Coil to coil tuner or Receiver makes electromagnetic fields created between two coils of this type occurs as electromagnetic fields that have the properties of magnetism (Magnetic) or conductive properties (Electrically Conductive) occurs as electromagnetic fields surrounding the area between the coils, the coil sends yalae receiver.ดังนั้นการพันขดลวดทั้งสองในตำแหน่งที่ถูก ต้องและเหมาะสมในบริเวณเครื่องตรวจจับโลหะจะมีผลต่อระดับความเข้มสนามแม่ เหล็กไฟฟ้าที่เกิดขึ้นในบริเวณของเครื่องตรวจจับโลหะและมีผลต่อความสามารถใน การตรวจหาวัตถุโลหะ ผลการศึกษาคุณสมบัติของโลหะที่มีคุณสมบัติทางด้านแม่เหล็ก หรือ คุณสมบัติตัวนำไฟฟ้านี้ จะมีผลต่อการตรวจจับสัญญาญของโลหะที่ปนเปื้อนมาในวัตถุที่เคลื่อนผ่านสนาม แม่เหล็กไฟฟ้าและถ้าระดับสัญญาญที่เกิดขึ้นระหว่างขดลวดทั้งสองประเภทนี้มี ความเข้มหรือความแรงของสัญญานอย่างเพียงพอแล้ว เครื่องตรวจจับโลหะจะตรวจวัดสัญญาญที่เกิดขึ้นและสามารถประมวลผลเพื่อทำให้ ผู้ควบคุมเครื่องตรวจจับโลหะรับทราบถึงการมีอยู่ของโลหะในวัตถุที่นำมาทดสอบFactors affecting strength or contract level. This depends on the distance between the coils in both categories. The figures, from the repositioning of the two types of stents, according to figure 1 and Figure 2, which is the positioning of the coil sends (Transmitter coil) more middle and secondary receiver (Receiver), press both sides of the wire bottle contract realm. To determine the distance between the coil and both sides must have the same distance, so the coil. Wire the receiver, the contract or contracts, strength levels yadai contract yathao together. The positioning of the two different types of coils The balanced or Balanced three-coil Coil coil is used, arrange themselves as indicated in picture 1, which has a coil sends headquarters is located in the middle between two coils of yathang contract by arranging the coils are arranged around the channel tunnel is designed for object moving through a tunnel, while the metal detection. Retrieve the channel tunnel as the Aperture, which is a thousand windings around the tunnel and arranging of the coil is a full-cycle system, also called a Full loop system.Contract yokluen-level metrics obtained from the receiving coil. The contract, the contract will be sent to the electrical yathang yani, received from the coils are the top two contract yathang. Characteristics of contract or opposite direction and strength of the contract, or from both. There are aspects of the same size, or contract. Make the total sum of the contract is zero yonwom or the balance of the contract conditions occur yadan left and right.From the development of the balance of the contract for this yafaifa us. Can compare the conditions apply to weight scales for comparison. The size of the contract or the contract labour placement yadan conductor (Conductive Scale) and magnetic yadan contract (Magnetic scale). According to the picture is a balance between features and guides. Magnet.From the electrical balance conditions. (The electrical equivalent), which compared to the balance of the scales that measure the level of contract and this Magnetic Conductive yadan. If there are metal, moving through the electric field or interference such equilibrium conditions. From the movement of contaminated metals materials through tunnels. Disturbed conditions such balance will send a contract. Yafaifa to represent the results of noise yafaifa contract yapai contract also happens to control the system, contraception, and detection systems, running and evaluation of changes in the contract, by yafaifa. Setting the detector is working at the strength of a promise or set or called the Sensitivity threshold to select or exclude materials that can send a contract yonbokwon electrical lead detection. Metal objects that may be contaminated are.From the results of the work in real conditions found. The obstacles that affect processing include the ability of the metal detector for aluminium packaging with plastic which has the property of iron and can cause electrical noise yathang contract cannot detect metal, because the effects of disturbing contract yafaifa of aluminum with plastic. Divided into groups according to the type of metal, the metal is divided into three groups:1. iron metals group is a component (Ferrous). 2. the Group of non-ferrous metals ferrous (non Ferrous) and.3. metal stainless steel group The metal detector is designed for monitoring group, which packaging online. Aluminum, plastic, it must rely on the system design of the metal detector and select the. Use the drivers that are specifically designed, called Ferrous detector in Foil to allow the use of metal detectors detect metal objects packed in aluminium with plastic packaging efficiently.Impact of product and value phase (Product and Phasing Effect.)From the principle of operation of the machine that is used to measure the level. Yathang this is the electrical contract, metal detectors will lead to contract such yadang. By the contract, this shall be measured or classification of the two types of contract, contract, yapen yadan magnets (Magnetic) and conductor (conductive) yadan.In the case of products moving through even though there is no metal, however, is the movement of products through the metal detector, will affect the balance of the contract to maintain a two-yathang. Shows that it features a macro way.
