MESEP AR Surface Detectors

Surface metal detectors for conveyor belts are electronic devices for detecting the presence of unwanted metal contamination in items moving along a conveyor belt. If you're worried about metal contaminants entering your process, and the conveyed item is fairly flat and no higher than 50 mm, then a surface detector is probably your best choice. Poorly maintained machines, the general wear and tear of the production machines are just a few of the ways that metal can enter your production process, ruin your grinder blades causing you thousands of dollars in production shutdowns.

To remove metals from your production process, a complete and total inspection of preassembled products is required to prevent these metals from leaving the plant and causing further damage. One possible solution involves examining the products at the end of the production line. Since all your products have to be transported to a conveyor belt at one time or another, a surface detector would be ideal for examining them while they are being moved to the conveyor.

Surface detectors are typically installed under the running belt cover. They can detect metal in the products above the running belt cover, but only in products that are not higher than 50 mm. Because they are located under the belt, they are not suitable for inspecting higher products, since their sensitivity decreases as the distance increases. The taller the product the less effective a surface detector will be. Anything higher than 50 mm is best analyzed by a tunnel detector.

MESEP AR

We offer a variety of surface detectors with varying detection capabilities in various module shapes. Choosing the right surface detector depends on the kind of product, its height and the type and size of metal to be detected. The MESEP AR surface detector is designed to be installed on a belt or shute conveyor. Only 35 mm high, this metal detector can be installed in places where space is limited. Available in three different sizes, these flat sensors can be installed side by side allowing you to scan a larger area. These detectors can also be arranged below and above the conveyor belt increasing the level of sensitivity.

*Between a 95 module and the adjacent element, there may be a maximum distance of 5 mm in order not to affect the scanning sensitivity. This makes it possible to increase the scanning width as required.
