Accurate weighing for any and every load

Thayer Scale’s conveyor belt scales are engineered for higher levels of accuracy, simplified calibration and exceptional repeatability. Manufacturers worldwide rely on our belt scales for inventory tracking, loadout verification, production monitoring and legal-for-trade transactions.

From fine powders to rugged materials our conveyor belt weighing systems deliver Built-to-Survive performance in every environment. In fact, several Thayer Scale products installed as far back as 1974 remain in operation today.

Measure what matters with our patented belt scale technology

Powered by our FMSS™ technology, our mass-counterbalanced conveyor belt scale designs offer a better way to maintain accuracy, improve measurement resolution and provide immunity to process disturbances.

Typical industry conveyor belt scales can get thrown off by external forces, resulting in inaccurate readings. Thayer Scale offers conveyor belt weighing designed to discriminate between net load measurement and undesirable extraneous forces – meaning the load cell measures only what matters – the material.

Key Benefits of Thayer Scale’s Conveyor Belt Scales

🎯 True Live Load Weighing
Dead load elimination maximizes load cell capacity to provide precise, reliable weighing —critical for accurate billing and inventory control.

⚖️ Stable Scale Zero
Proven immunity to zero bias and shifts provides a stable scale zero — the essential foundation for continuous weighing accuracy for conveyor belt scales.

⚙️ Built To Survive
Our heavy-duty conveyor belt scales feature durable, robust construction designed to withstand the shock load of thousands of tonnes an hour in harsh environments.

🧮 Verifiable Calibration Made Safe & Easy
We offer designs that let a 50 lb test weight simulate the effect of 1,000s of pounds of material load—physically exercising the scale for calibration. Unlike resistor-based calibration that may hide system errors, physical test weights exercise the scale lever for trustworthy calibration.

📐 Flexible Configurations
Our conveyor belt scales can be easily configured to meet operational and cost objectives. Thayer Scale offers belt scales with weigh sections consisting of between a single to up to eight idlers and belt widths from 14″ to over 96″.

📊 Weighing Accuracy To Fit Your Process
(0.10%–0.125%) High‑accuracy systems for loading/unloading and custody transfer (NTEP-approved) or ( 0.25%–0.5%), ideal for inventory control and in‑process weighing (0.5%–1.0%) or rugged and reliable for stone, aggregate, and bulk materials.

🧾 NTEP‑Certified Options Available
NTEP-certified options provide the legal assurance and confidence needed to sell directly from the scale.

🌐 Proven Across Industries
Trusted worldwide by leading operations in fertilizer, mining, ore, coal, pulp & paper, and tobacco—our conveyor scales perform reliably in both heavy-duty and light-loading applications.

Our Conveyor Belt Scale Core Technologies

Many of Thayer Scale’s conveyor belt scales feature unique and patented technologies that outperform traditional conveyor belt scale designs.

Force Measurement Suspension System (FMSS)
Our patented FMSS™ technology is able to discriminate between net load measurement forces and all other undesirable extraneous forces, making load cells virtually immune to the detrimental effects of vibration, significantly improving weighing accuracy.

🔄 Rocking Flexure Suspension Weighbridge
Our specialized weighbridge design uses a rocking flexure to maintain accuracy in both approach or approach/retreat configurations, by minimizing errors caused by lateral forces and hysteresis.

🛡️ High Sensitivity Load Cell Isolation
A single load cell is isolated from lateral forces, off-center loading, foundation distortion, shocks, and overloads—ensuring consistent, reliable weight measurement even in demanding conditions.

🎚️ Mass-Counterbalanced Design
Thayer Scale’s mass-counterbalanced conveyor belt scale design weighs only the live load thus maximizing the load cell’s utilization, improving signal-to-noise ratio for better weight-sensing accuracy.

🌀 Precision Belt-Travel Sensing Wheel
A fixed-circumference precision sensing wheel, securely mounted to conveyor stringers, accurately measures belt travel for precise weight calculations.
