By far the most multipurpose type is the X-Ray Screening Machine For Luggage, where the material is gravity fed through the inlet of the detector. Metallic particles are detected and immediately rejected by an air-operated rejection system. Adjustable sensitivity in conjunction with short rejection time ensures minimal loss of good product.
Free-fall units can be found in single-coil or balanced-coil designs and with either analog or digital electronics. Free-fall units may range in aperture size from 25 to 300 mm (1 to 12 in.). Some types use a quick-clean rejection system that facilitates cleaning of the reject system.
Metal detectors for pneumatically conveyed materials take the form of a collar surrounding the conveying line. Again, these detectors can be purchased in single- or balanced-coil design with analog or digital electronics. Positive speed control is accessible on some models to precisely time the reject-gate closing and opening in order to minimize losing good material.
Metal detectors for mechanical conveyors take the type of a tunnel surrounding the conveyor. This technique could be coupled with many different customized rejection options for loose or packaged materials. Metal detectors for films and thin sheets use coils which are extremely sensitive at close range. They can fit directly under the web and require almost no space.
Separators for plug-flow applications are similar in operating principle to a free-fall detector. However, the plug-flow design detects metals in slow-moving or standing columns. An average application is mounting the system under the hopper and just over the throat of the processing machine. At Bunting Magnetics, we call this the “Last Chance Separator” or LCS. The LCS is built to support batch feeders, blenders, along with other processing equipment weighing approximately 250 lb. Devices are bolted directly to the infeed of the LCS.
Add a magnet – Place a drawer, grate, hump, liquid-trap, or some other magnetic separation unit upstream to do business with your detector. Magnetic separators will pull all ferrous metal out before it reaches the detector. This can lighten the burden of contaminants that pass through the detector, increasing its efficiency while minimizing the likelihood of rejecting good material. In addition, utilization of an upstream magnet lets you adjust the detector’s sensitivity to a higher level to capture only non-ferrous contaminants.
The detection system consists of a pulse/echo transducer, a water jet nozzle and an x-y table. Foreign bodies like glass, Walk-Through Metal Detector were detected by scanning the flat bottom in the beverage container. According to acoustic modeling, a technique for detection and identification of foreign bodies is developed and tested. A signal processing algorithm for time-frequency analysis is utilized to discriminate between beverage and contaminants from ultrasound echoes. Effective detection ability for materials including glass, metals, and plastic, with sizes from 10 to 2.5 mm2 is demonstrated. Experiments were also performed using ultrasonic beam penetrating glass material to detect steel balls of different sizes. This can be closer to the case of real foreign body when it comes to orthogonality and cross-section to ultrasound beam.
Detection of metallic and non-metallic objects – Sometimes you just need to understand what is hidden behind a surface. As an example behind a wall or cover, or what is inside in a storage container or shipping container. Capacitive proximity sensors are best for level and feed monitoring. From solid material, like paper or wood, to granules or liquids, they reliably detect the status in the product throughout the production process and final inspection. Is there something behind that cover? Is the filled package really full?
How much paint remains left inside the tank? For capacitive proximity sensors, these are easy inquiries to answer. Capacitive proximity sensors from SICK are never far away from the action. Sensing ranges between 1 and 25 mm let them be used in nearly all installation situations, causing them to be extremely adaptable for an array of applications. These sensors pbgavn also remarkably resistant against faults. Impurities, contamination, dust, and airborne spray particles have little influence on them, nor does electromagnetic interference. No wonder they may be installed in a great deal of industries, including food, automotive, or perhaps in storage and conveyor systems.
Reliable, powerful, rugged. Inductive proximity sensors from SICK – Millions of inductive proximity sensors are presently being used in nearly all industries. They X-Ray Baggage Scanning Machine without contact, and are seen as a a lengthy service life and extreme ruggedness. With all the latest ASIC technology, SICK’s sensors provide the epitome of precision and reliability. SICK can provide the best means to fix meet your requirements each time – from cylindrical or rectangular standard sensors with single, double or triple operating distance, to special sensors for explosive zones and harsh environments. Our sensors are definitely the intelligent, reliable path to implementing industry-specific and customized solutions to any task involving automation.
