Thayer Conveyor Belt Scales:

Precision Weighing Built to Survive

Thayer Scale designs conveyor belt scales for precise, repeatable weighing in demanding industrial environments. Each system is built to deliver high accuracy and long-term reliability, even under harsh operating conditions.

At the core of every belt scale is Thayer Scale’s patented Force Measurement Suspension System (FMSS), which isolates the net material load from external forces such as vibration, belt tension, and structural distortion. This ensures that only the true conveyed weight is measured, improving accuracy and reducing calibration drift.

Thayer Scale offers models ranging from single-idler to eight-idler configurations, supporting belt widths from 14 inches to over 96 inches. Accuracy levels vary by application, with options available for:

• High-precision custody transfer (±0.10% to ±0.125%)
• Inventory control and production tracking (±0.25% to ±0.5%)
• Bulk material handling in rugged environments (±0.5% to ±1.0%)

Each weighbridge features a mass-counterbalanced design that maximizes load cell signal strength and minimizes the impact of overloads. The rocking flexure suspension system provides permanent axis alignment and resists lateral forces, maintaining consistent performance across a wide range of operating conditions.

Thayer Scale’s belt scales are used in industries such as mining, coal, fertilizer, biomass, pulp and paper, and chemicals. Many systems have been in continuous operation for decades, a testament to their durability and engineering quality.

Key features include:

• Stable zero tracking for consistent baseline accuracy
• Mechanical test weight calibration for reliable system validation
• Precision belt travel sensing using a fixed-circumference wheel
• NTEP-certified models for legal-for-trade applications

Thayer Scale provides flexible configurations to meet specific operational needs, with options for custom engineering, integration with control systems, and remote diagnostics. Whether the application requires high-accuracy loadout or robust performance in aggregate handling, Thayer Scale delivers solutions that are built to survive and engineered to perform.
