Kenwei PrecisionGuard Industrial Metal Detector & Multihead Weigher

Kenwei PrecisionGuard is a combined industrial metal detection and multihead weighing solution that protects product integrity while maximizing throughput. Designed for manufacturers who demand speed, accuracy and minimal waste, it pairs Kenwei’s trusted weighing technology with reliable contaminant detection to stop metal foreign bodies, reduce recall risk, and deliver consistent package weights on high-speed production lines.

Core Advantages

Protects Brand and Reduces Risk

With integrated metal detection and precision weighing, PrecisionGuard identifies metal contaminants early and rejects affected product before packaging. That protects Kenwei reputation, minimizes costly recalls, and keeps compliance documentation straightforward.

Faster Line Speeds with Fewer Giveaways

Kenwei’s multihead weigher design focuses on rapid, accurate portioning to reduce overfill while maintaining target weights. The result: higher throughput without sacrificing quality or increasing giveaway costs — ideal for snack, frozen, bakery and pet food producers.

Simple Integration and Easy Operation

Designed for real production environments, PrecisionGuard integrates into common packaging lines with intuitive controls and clear status feedback. Operators spend less time troubleshooting and more time running product, reducing downtime and training needs.

Unique Features

High Precision Multihead Weighing

Kenwei’s multi-head system offers consistent portion accuracy across a wide range of product types and sizes. Its modular design supports quick changeovers and customization to match specific product profiles.

Reliable Contaminant Detection

The metal-detecting capabilities are engineered to find ferrous, non-ferrous and stainless contaminants without slowing the line. Use of robust detection reduces false rejects and maintains product flow.
