Patented Vibration Technology
ProScan vibration technology monitors interference created by vibration and automatically compensates for the effect, thus enhancing reliability and sensitivity.

Patented Auto Balance
Advanced Detection Systems’ auto-balance software maintains perfect coil balance and optimum performance, eliminating the cost of a service technician plant visit to re-balance the metal detector.

Proper conveyor design is a critical feature of your metal detection system. Advanced Detection Systems metal detector experts will evaluate your product’s size, weight and throughput to ensure that your metal detector and conveyor achieve state of the art, reliable metal detection and the entire system is properly incorporated into your existing production process.

Advanced Detection Systems’ wash down enclosure design is the best in the industry!

Our ProScan Conveyor System is rated IP69K for sealing of the electronics and extreme wash down conditions. We designed the ProScan metal detector series to withstand high pressure wash down environments. The ProScan Conveyor System is preferred by food processors because it prevents water from getting into the coil, which is encapsulated with waterproof material. Stainless steel housing is embedded into PVC at a 90° angle – unlike other detectors where water can seep through a vertical seam – resulting in costly repairs. The welded construction and stainless steel components are designed to provide many years of reliable performance. The seams are sealed under pressure using extra mounting bolts. The sealant acts as a pressurized gasket to form a superior seal against harmful water ingression. We included an impact resistant touchscreen cover. The metal detector can withstand close range wash downs at an average rate of four gallons per minute with water pressures between 1160 – 1450 psi and at a temperature of 176°F.

ProScan Conveyor System Optional Rejection Devices and Accessories

Advanced Detection Systems’ engineers are experts in metal detection. We manufacture superior reject devices and accessories to meet your application requirements. Any reject device and accessory can be customized or designed to your specific needs.

Reject devices are used to allow the customer to remove contaminated product and still maintain normal product flow without halting production. The use of a reject device also allows the company to avoid relying on the employee to remove the contaminated product from the line.

Having a reject device for your ProScan Conveyor System is important. The reject device will prevent contamination, protect your customers, provide a stellar reputation of your product (brand name) and protect your profits. The product or the package of the product will determine which type of reject would be best for the application.

How to determine which reject device is appropriate for you?

The ProScan Conveyor System has a variety of reject devices and accessories available:

Sweep Arm Reject Device – Ideal for packaged products on conveyor belts that are 12" or less.

Metal Detector - ProScan Conveyor System

Sweep Arm Reject Device w/Discharge bin

A sweep arm reject is an arm that sits on the side of the conveyor, parallel to the belt; it swings out at a 45 degree angle to knock the contaminated product off of the conveyor belt.  The sweep arm reject is again used on narrow belts up to 12" and generally for packaged products such as portioned meat, vegetables, and products in poly bags. Because the arm swings out to a 45 degree angle, it can become very cumbersome if the arm is too long. Even with a 12" belt, the arm is 17" long.  With an 18" belt the arm becomes 25" long and 34" long with a 24" belt. You can see how the arm can become “whippy” and knock off a lot of good product.

Divert Arm Reject Device – Perfect for a “gentle” contact with the product and for rejecting product. Spacing and belt speed must be taken into account when considering a divert arm reject device.

The divert arm is very similar to the sweep arm except it pivots at the far end. The leading edge comes out in front of the product and “diverts” the rejected container to the holding area.

Air Blast Reject Device – Simple and economical method for removing light weight packaged products from belt widths of 12" or less.

Air Blast Reject Device w/discharge bin

The air blast is the simplest and least expensive reject device available. If the product is light enough and if there is a flat surface to blow against, the air blast is the way to go.  It is also important that the conveyor belt not be too wide, usually up to about 12".  The air blast is generally used with packaged products but can be used with some bulk unpackaged products as well.  Typical products that can use an air blast are small boxed items like candies, noodles, snack foods, cereals, and even some heavier products as long as there is a flat surface and the belt is not too wide.

Push Arm (RAM) Reject Device – Ideal for removing heavy boxed product.

RAM Reject Device w/discharge bin

Push arm or “ram” – This reject device is a straight arm cylinder that sits perpendicular to the conveyor belt and pushes across the belt at a right angle. Timing is a major consideration for this reject and it is usually only used on narrow (12” or less) belts and at slower speeds.  A typical product would be a small case of bakery type products or snack foods.   If the belt speed is too fast the reject cannot be retracted quickly enough and the good product starts getting caught up in the arm of the reject.  The push arm can be used for both packaged and loose products.  There are variations of the push arm that can be used on wider belts.  Because of the way the push arm type reject is built and mounted, a straight stroke air cylinder will stick out quite far from the side of the conveyor.  You can see that if the belt is 18” wide or even wider that the straight stroke air cylinder is not practical.  Both the retracting problem and the mounting problem are solved by the use of a rod less air cylinder.  The cylinder sits above the belt with a paddle hanging down to move the product from side to side.  This also allows us to use the reject device on wider belts if required.

Retracting Pulley Reject Device – Best choice for bulk or sticky product and packaged products on conveyor belts that are wider than 12”. If the product does not slide easily, like fresh hamburger patties or some types of sticky products, then you must use a retracting pulley type device.  In this instance the discharge pulley of the conveyor is made to move in 6-8” to create a gap that the contaminated product can fall through rather than feed directly to the take away conveyor.  This also can be used with any width conveyor belting.  The major disadvantage with this reject is the price and the fact that we can only retract about 10” at the maximum.

Flop Gate Reject Device – Designed for efficient rejection of dry, bulk products on conveyor belts of any width. The flop gate reject device is used at the end of the conveyor and is generally for loose or bulk product.  Typical products would be cookies, frozen meat patties, candies, and many vegetables.  The flop gate is a sheet of stainless steel or UHMW that sits at the end of the conveyor at a 45 degree down angle.  The product exits the conveyor and slides down the flop gate to the take away conveyor.  If metal is detected, the flop gate rotates 90 degrees and instead of feeding onto the next conveyor the product is rerouted to a reject container of some kind.  Timing of this reject is pretty easy and the flop gate can be used with any width conveyor belt.  Two drawbacks with this reject device are that the product needs to slide easily down the 45 degree angle and, because of the lower discharge height; the conveyor may need to be elevated.

Other Reject Devices:

Stop Conveyor – This is our most common type of reject device and comes standard on all conveyors that we manufacture. It is the most cost efficient and is used with very heavy or extremely delicate products. It is easily disabled if the customer does not want the belt to stop.

Audible or Visual Alarms – A variety of horns, bells, buzzers, flashing lights, rotating beacons, etc. are also available.

Reject light, Validation light and Horn

External Remote Control Cabinet – The external remote control cabinet is an optional accessory used when the ProScan Conveyor System is placed in a difficult to read position in your production stream.
