Linear Weigher vs Multi-Head Combination Scale
When selecting between a linear weigher and a multi-head combination scale, overseas owners face a critical trade-off: speed, precision, and cost. The choice hinges on material characteristics, target weight range, production volume, and budget — not just technical specs. This guide cuts through marketing noise to reveal real-world performance differences using only documented model codes and parameters from CECLE’s official product line.
Decision Matrix: Key Factors at a Glance
| Decision Factor | TD-2M Dual-Head Linear Weigher (Model TD-2M) | TD-4M 4-Head Linear Weigher (Model TD-4M) | TD-10-0.5L 10-Head Combination Scale (Model TD-10) | TD-14-0.5L 14-Head Combination Scale (Model TD-14) |
|---|---|---|---|---|
| Weighing Range | 20–2000 g | 20–2000 g | 50–1000 g | 50–2000 g |
| Average Precision | 1–2 g | 1–2 g | 0.1–1 g | 0.1–1 g |
| Max Packing Speed | 30 bags/min | 30 bags/min | 60 bags/min | 60 bags/min |
| Material Suitability | Granules, free-flowing powders (e.g., sugar, rice, MSG) | Same as TD-2M; better for mixed batching | High-value granules, coffee beans, seasonings, small slices | Same as TD-10; wider range for large-dose blends |
| Cost Position | Entry-level | Mid-tier | High-end | Premium |
| Key Strength | Low cost, simple operation, stable performance | Better mixing capability, moderate speed | Extreme accuracy, high-speed automation | Ultimate precision across wide range, superior mixing |
This table reveals a clear hierarchy: linear scales offer simplicity and affordability, while multi-head combination scales deliver unmatched precision and throughput — but at a steep price.
Which Should You Choose? Scenario-Based Guidance
For startups or small workshops processing moderate volumes (≈30 bags/min) of standard materials like rice, salt, or tea leaves, the TD-2M dual-head linear weigher is ideal. Its 1–2g average precision meets most food-grade requirements, and its compact footprint (108×95×118 cm) fits tight spaces. It’s also perfectly paired with a VFFS machine or used semi-automatically with foot pedal discharge. For customers needing proportional mixing (e.g., "mixed nuts" or "herb blends"), the TD-4M 4-head version offers better flexibility without crossing into premium territory.
However, if your product is high-value, such as specialty coffee beans, rare seeds, or premium spices, the TD-10 or TD-14 combination scale becomes essential. The 0.1–1g precision directly reduces over-giving — a major cost center in high-margin goods. A single gram saved per bag across thousands of units translates to significant profit improvement. The TD-14-0.5L, with its 14-head algorithm and 2000g upper limit, excels in complex blends like eight-treasure porridge mix or multigrain snacks where consistency and accuracy are non-negotiable.
Avoid the temptation to use a linear scale for high-precision tasks. While both TD-2M and TD-4M claim “1–2g” accuracy, this is an average — actual results depend heavily on material flow and particle size. Dusty or irregular materials will push error margins higher. In contrast, the combination scale’s ability to calculate thousands of possible combinations ensures near-perfect targeting even under variable conditions.
Operating Costs & Utilities
All four models operate on AC220V ±10%, 50Hz (60Hz), with power consumption ranging from 1.2kW (TD-2M/TD-4M/TD-10) to 1.2kW (TD-14). Despite similar electrical draw, long-term operating costs differ significantly due to material waste. A linear scale may overfill by up to 2g per package — negligible for bulk grains but catastrophic for coffee beans priced at $50+/kg. The combination scale’s 0.1–1g tolerance minimizes this loss, making it more economical over time.
Maintenance is another factor. Both TD-2M and TD-4M feature modular control systems, simplifying repairs. However, the TD-10 and TD-14 include advanced algorithms and stepless vibrating feeders that reduce wear on mechanical components. Their stainless steel hoppers are designed for easy disassembly — crucial for hygiene in food processing. For facilities prioritizing uptime, the robustness of the combination scale’s architecture pays dividends.
Real Models: From Small to Large-Scale Weighing
The TD-2M and TD-4M represent the accessible end of CECLE’s weighing portfolio. Designed for granular materials with consistent flow, they are best suited for products like sugar, sesame, milk powder, or dried herbs. Their 30-bags-per-minute speed aligns well with mid-range VFFS machines. These models can be integrated into semi-automatic lines or linked to conveyor systems via signal triggers.
In contrast, the TD-10-0.5L and TD-14-0.5L are engineered for high-throughput automated packaging lines. They require a matching bucket elevator (Z-type recommended) and working platform due to their size and weight (250KG and 380KG respectively). The TD-14-0.5L’s dimensions (1650×1080×1110 mm) demand careful site planning — ceiling height must exceed 1.1m, and floor load capacity should support 380KG.
These combination scales are not standalone tools. They function as core components within larger systems. For example, pairing the TD-14 with a vertical form-fill-seal (VFFS) machine creates a fully automated line capable of handling 60 bags/min. Similarly, the TD-1C1 dynamic checkweigher (model TD-1C1) acts as a final QC gate — detecting missing manuals or underweight packages — ensuring compliance before shipment.
FAQ
Q1: Can I use a TD-2M to weigh powdered ingredients like instant coffee? A1: Only if the powder flows freely and isn’t dusty. The TD-2M is suitable for coarse powders like MSG or seasoning mixes, but not for ultra-fine or clumping materials. For milk powder or fine herbal extracts, consider the FM series (e.g., FM-9999 or FM-50) or a screw metering system instead.
Q2: Is the TD-14-0.5L worth the extra cost over the TD-10? A2: Yes — if you need to handle weights above 1000g or blend multiple materials with strict ratios. The 14-head configuration provides more combination options, improving accuracy across a broader range. It’s especially valuable for clients producing varied-sized packs (e.g., 100g, 500g, 1kg) without changing equipment.
Q3: How do these scales integrate with existing packaging lines? A3: All models support signal-based integration with VFFS machines, conveyors, and control panels. The modular design allows seamless connection to upstream feeders (like bucket elevators) and downstream packers. For full automation, pair with CECLE's complete packaging solutions — including VFFS machines, screw feeders, and checkweighers.
