Probably the most adaptable type is the Easy Operation Bomb Detector, 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 coupled with short rejection time ensures minimal loss of good product.

Free-fall units can be found in single-coil or balanced-coil designs with either analog or digital electronics. Free-fall units can vary in aperture size from 25 to 300 mm (1 to 12 in.). Some types use a quick-clean rejection system that facilitates cleaning in the reject system.

Metal detectors for pneumatically conveyed materials take the shape of a collar all around the conveying line. Again, these detectors are available in single- or balanced-coil design with analog or digital electronics. Positive speed control can be obtained on some models to precisely time the reject-gate opening and closing so that you can minimize the losing of good material.

Metal detectors for mechanical conveyors take the type of a tunnel surrounding the conveyor. This method could be along with a number of customized rejection options for loose or packaged materials. Metal detectors for films and thin sheets use coils which can be extremely sensitive at close range. They can fit directly underneath 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 underneath the hopper and just over the throat of the processing machine. At Bunting Magnetics, we refer to this the “Last Chance Separator” or LCS. The LCS is built to aid batch feeders, blenders, and other processing equipment weighing up to 250 lb. Devices are bolted right to the infeed in the LCS.

Put in a magnet – Place a drawer, grate, hump, liquid-trap, or any other magnetic separation unit upstream to work alongside your detector. Magnetic separators will pull all ferrous metal out before it reaches the detector. This may lighten the burden of contaminants that move through the detector, increasing its efficiency while minimizing the chances of rejecting good material. In addition, usage of an upstream magnet allows you to adjust the detector’s sensitivity to your higher-level to catch only non-ferrous contaminants.

The detection system consists of a pulse/echo transducer, a water jet nozzle and an x-y table. Foreign bodies including glass, Underground Mine 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 can be used to discriminate between beverage and contaminants from ultrasound echoes. Effective detection ability for materials such as 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 numerous sizes. This really is nearer to the situation of real foreign body when it comes to orthogonality and cross-section to ultrasound beam.

Detection of metallic and non-metallic objects – Sometimes you need to simply know what is hidden behind a surface. For instance behind a wall or cover, or what exactly is inside in a storage container or shipping container. Capacitive proximity sensors are ideal for level and feed monitoring. From solid material, such as paper or wood, to granules or liquids, they reliably detect the status in the product during the production process and final inspection. Can there be something behind which cover? Is the filled package really full?

Just how much paint is still left in the tank? For capacitive proximity sensors, they are easy inquiries to answer. Capacitive proximity sensors from SICK are never far from the action. Sensing ranges between 1 and 25 mm let them be utilized in nearly all installation situations, causing them to be extremely adaptable for a wide range of applications. These sensors pbgavn also remarkably immune to faults. Impurities, contamination, dust, and airborne spray particles have little effect on them, nor does electromagnetic interference. No wonder these are installed in a great deal of industries, like food, automotive, or perhaps in storage and conveyor systems.

Reliable, powerful, rugged. Inductive proximity sensors from SICK – Countless inductive proximity sensors are in use in nearly all industries. They Airport Body Security Scanner without contact, and therefore are described as an extended service life and extreme ruggedness. Using the latest ASIC technology, SICK’s sensors offer the epitome of precision and reliability. SICK provides the right solution to meet your needs every 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 would be the intelligent, reliable way to implementing industry-specific and customized methods to any task involving automation.
