Checkweigher Combinations with Metal Detection
Combined checkweigher-metal detection systems represent the pinnacle of production line quality control, merging two essential inspection technologies into a single, space-saving unit. These advanced systems simultaneously
verify product weight compliance while screening for metallic contaminants - from tiny metal fragments to larger foreign objects.
Unified Frame Design: Single stainless steel (typically 304 or 316 grade) housing containing both systems
Sequential Inspection Process:
Initial Product Scanning: Metal detection occurs first to prevent contaminated products from affecting weight measurements
Precision Weighing: Dynamic weighing cell captures exact product mass
Automated Sorting: Dual-rejection capability for both weight and contamination failures
