Our ProScan Max® III 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® Max III 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. The control panel door is sealed to specifications and has an impact resistant touch screen 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.
IP69K Wash Down Definition:
IP= Ingress Protection (the degree of protection provided by the electrical enclosures)
6= Dust Tight
9K= High Pressure/High Temp Spray Down
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:
Optional Reject Devices
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/Lockable Reject Collection 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 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/Lockable Reject Collection 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.
Push Arm (RAM) Reject Device w/Lockable Reject Collection 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.
Validation Light, Detect Light and Horn
Advanced Detection Systems offers accessories that can be incorporated into the existing metal detection system as needed to meet your specific needs. Our accessories are beneficial in many ways: accessories protect the product stream, ensure employee safety and optimize operation in extreme temperatures.
Lockable Reject Collection Bin – Securing access to rejected product is critical to meeting food safety regulations and ensuring rejected product does not get returned to the production line. Lockable Reject Collection Bins prevent unauthorized access to rejected product before it can be inspected and the cause of the metal contamination determined by Quality Assurance personnel. Our reject collection bins are made of Type 304 stainless steel and come with a lockable, clear polycarbonate access door. Existing conveyors can be retrofitted with a Lockable Reject Collection Bin depending on design. Contact us for details.

Fixed Side Guides – Your product’s orientation through the metal detector is a factor in determining sensitivity. Consistent orientation will help improve sensitivity levels and reduce product effect. Fixed Side Guides can be used to keep unstable product from tipping during conveyor transfer, re-orient slightly misaligned products and keep bulk materials from falling off the side of the conveyor. Fixed Side Guides cannot be adjusted after construction.
Fixed Side Guides
Adjustable Side Guides – Your product’s orientation through the metal detector is a factor in determining sensitivity. Consistent orientation will help improve sensitivity levels and reduce product effect. Adjustable Side Guides can help re-orient products presented to the metal detector in varying directions. The position of these guards can be adjusted to suit your product requirements.
Adjustable Side Guides
Infeed Hoppers – An Infeed Hopper can be used to collect and funnel product through your metal detector with consistency. Infeed Hoppers can be used with gravity or conveyor configuration of metal detector. Hoppers can be built to your application and product specifications.
Touchscreen Cabinet Heater – Metal detectors used in environments below 40⁰F should be equipped with a Cabinet Heater to reduce condensation buildup and prevent the LCD screen from becoming lethargic or difficult to read in cold temperatures. The Cabinet Heater has a built in thermostat to regulate temperature.
Touchscreen Cabinet Heater
Web-Enabled Touchscreen – The Web-Enabled Touchscreen allows the metal detector to be connected to a local network. The detector can be monitored and controlled remotely from any device with an internet browser (your device must be connected to the same network as the metal detector). The Web-Enabled Touchscreen makes data collection easier by allowing the data-log files to be downloaded directly to a computer. The ability to monitor, control and review data with the Web-Enabled Touchscreen requires no additional proprietary software.
