Kenwei Advanced Metal Detection System — Precision Protection for Automated Weighing Lines

Kenwei’s metal detection system is engineered specifically for seamless integration with multihead weighers and automated packaging lines. From a systems perspective, we provide configurable communication protocols (PLC, Ethernet/IP, and digital I/O) and mechanical designs that match conveyor widths and line speeds so the detector fits as an inline station without disrupting throughput. Integration benefits include continuous in-line inspection at production speed, real-time reject signaling to downstream equipment, reduced risk of product recalls, and consistent product quality. Our team supports onsite installation, commissioning, and staff training to ensure your line operates smoothly from day one.

Kenwei metal detectors are built to detect ferrous, non-ferrous (aluminum, copper) and stainless-steel contaminants. Sensitivity depends on product type, packaging, and detector configuration; however, our systems use advanced digital signal processing and multi-frequency technology to detect very small metallic particles—even sub-millimeter fragments in many applications—while minimizing false rejects. During commissioning we perform product-specific set-up and verification tests to document detection limits for your products and provide written validation data to support your food safety plan.

Compared to other latest metal detectors, Kenwei emphasizes practical integration with high-speed weighing and packaging equipment alongside advanced detection algorithms. Our units combine multi-frequency detection, adaptive product-effect compensation, and robust construction for washdown or dry environments. The result is high sensitivity with strong immunity to product and environmental interference, lower false-reject rates, and reliable performance at high line speeds. As a manufacturer of both multihead weighers and metal detectors, Kenwei offers end-to-end solutions—reducing compatibility issues and accelerating deployment—backed by local installation, training, and after-sales service.

Kenwei provides clear, practical protocols for calibration and validation: initial factory setup and site-specific calibration during commissioning; routine daily or shift-level verification checks using standard test pieces; and scheduled in-depth validation (typically monthly or as required by your quality program) that includes documented test logs. Maintenance is minimal: keep search head and conveyor clean, inspect reject mechanism for wear, and update firmware periodically. For customers who prefer hands-off support, we offer service contracts that include periodic preventive maintenance, remote diagnostics, and rapid on-site response to minimize downtime.

A Kenwei metal detection system helps you meet and demonstrate adherence to international food safety expectations (e.g., HACCP-based requirements and FDA guidance) by providing documented inspection, validation, and traceability. This reduces the risk of costly recalls, protects brand reputation, and lowers potential liability. From an ROI standpoint, our detectors minimize product loss through precise rejection control, maintain high line efficiency at speed, and reduce manual inspection needs. Kenwei also provides customized system configurations and cost-effective one-stop solutions—combining weighers, checkweighers, and detectors—to optimize capital and operational expenditure.
