Model 3RF-6ALA
High-Accuracy Belt Scale for Light Loading Applications
Thayer Scale’s 3RF-6ALA conveyor belt scale was specifically designed for high accuracy (¼% typical) inventory control and throughput totalization of light scale loading applications such as wood chips, saw dust, grain and Biomass. Thayer’s Belt Scale weigh bridge features exclusive rocking flexure suspension in the approach configuration. Measurement sensitivity is high, deflection is low, and the load cell is isolated from the error-inducing effects of extraneous lateral forces, off-center loading, foundation distortion, inclination hold-back forces, and high sporadic shocks and overloads. Tare load is mass counterbalanced to create superior signal to noise ratio in weight sensing, orders of magnitude better than belt scale designs supporting full tare load on the load sensor.
Industry Applications
Suitable for light loading and low density dry bulk material weighing.
- Forest Products: wood chips, sawdust
- Tobacco: flakes, shredded leaf
- Food and agriculture: grains, rice flakes, cereals
- Chemicals: Light industrial powders and chemicals

Key Benefits
of Thayer Scale’s Model 3RF-6ALA High-Accuracy Conveyor Belt Scale
🎯 Reliable Accuracy for Light Loading
Measures light material flows (under 10 lb/ft) with consistent, verifiable accuracy.
🎚️ Only Measures What Matters
Powered by our FMSS™ technology, our mass-counterbalanced conveyor belt scale is designed to discriminate between net load measurement and undesirable extraneous forces.
🧱 Built to Survive
Our secondary lever and RF flexure design resist shocks, lateral forces, and overloads >1,000 lbs without compromising accuracy.
🌀 Precision Belt Speed Sensing
A precision speed sensing wheel resists material buildup and delivers reliable speed signals—critical for accurate totalization.
🔧 Simplified Maintenance & Calibration
Field-adjustable tare, easy access to load cell and mechanical test weight system simplify setup, calibration and verification.
⚖️ A Winning Combination
Thayer Scale’s RF belt scales with FMSS mass-counterbalanced technology ensures better than 80% load cell utilization.
Core Technologies
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.
Rocking Flexure Suspension
Our patented RF Flexure suspension system provides permanent axis stability with near-zero hysteresis and immunity to lateral force interference.
Secondary Lever System
Our secondary lever system mechanically counterbalances tare loads up to 200x net load, reduces idler deflection, and self-aligns under structural distortion.
Weigh Bridge
The secondary lever system uses stainless steel aircraft cables as flexural elements which transmit pure tension forces while allowing lateral movement to accommodate conveyor twist.
Load Cell Options
Choose from LC-137 LVDT or LC-174 Strain Gauge for optimal performance across conditions and certifications.
