Metal detectors: Ten tips for achieving reliable long-term performance
Electronic metal detectors for dry bulk solids applications are highly sensitive radio-frequency instruments that need regular TLC. Here are 10 practical tips for keeping your metal detector on top of its game for the long term -- reliably rejecting contaminated material while letting good product keep on flowing.
Metal fines and larger debris (tramp metal) can get into dry bulk solid products, including foods, pharmaceuticals, chemicals, and others, from several sources. While careful equipment design and operation can prevent many sources of metal contamination, it's impossible to entirely eliminate metal from contaminated ingredients and imperfect processes. That's why metal detectors for locating and rejecting products contaminated with metal are a critical element of many processing lines and especially in FDA-recommended Hazard Analysis and Critical Control Point (HACCP) programs.
