How to Choose the Right Metal Detection Equipment

The first step in choosing inspection equipment is to clarify the detection object and goal. Needle detectors target broken needles and ferrous metal and suit apparel, footwear, toys and home textiles. Metal detectors detect iron, stainless steel, copper and aluminum and suit food, pharmaceutical and packaging industries.

Next, match the aperture size to the product. The aperture must accommodate the largest product cross-section, but a larger aperture generally lowers sensitivity, so a balance between pass-through size and detection accuracy is required. Detection accuracy is the core performance indicator and should be set according to the tolerable contaminant size.

Also consider line speed, conveying method, installation space and whether automatic rejection is needed. It is recommended to provide product type, size, accuracy requirements and line speed so that engineers can recommend a matching model.
