Linear Weigher vs. Multihead Weigher: Which Weighing Technology Wins?

1. The Core Logic: “Single Shot” vs. “Best Combination”

The biggest difference lies in the “brain” of the machine:

• Linear Weigher: It feeds material into a single bucket until the target weight is reached. It’s a direct, sequential process.

• Многоголовочный весовой дозатор: It distributes material into multiple buckets (e.g., 10 or 14 heads). The computer then instantly calculates thousands of combinations to find the single best match to your target weight.

2. Accuracy & Waste: The ROI Factor

• Multihead Weigher (High Precision): Because it chooses the best combination, the “giveaway” (overfilled product) is minimal—often within $0.1g$ к $1g$. While the initial price is higher, it pays for itself by saving expensive raw materials.

• Linear Weigher (Budget-Friendly): It’s more affordable but less precise. If you are packing 5kg of low-cost seeds where a $10g$ fluctuation doesn’t hurt your margin, the Linear Weigher is a cost-effective workhorse.

3. Application Scenarios: Where They Shine

• Linear Weigher: Лучше всего подходит для loose, free-flowing, small-granule materials where the total volume or weight is relatively large. Think of large bags of sugar, rice, or fine detergents.

• Multihead Weigher: Its versatility is unmatched. With its many “variants” (like scraper hoppers for sticky seaweed or dimpled plates for frozen food), it solves complex problems that linear weighers simply can’t handle. It is the go-to for snacks, hardware, frozen foods, and fragile items.
