Model 6RFS-6/8
Thayer Scale’s high-accuracy scales feature a multi-idler mass counterbalanced weighbridge for superior performance
Thayer Scale’s 6RFS-6/8 conveyor belt scale is a 6-idler design specifically engineered for production tracking, process optimization and high-accuracy inventory control and totalization where accuracy is key (⅛% typical). Its multi-idler design delivers robust, repeatable weighing for the harshest environments.
Featuring Thayer Scale’s mass-counterbalanced design leveraging our exclusive FMSS™ technology and unique secondary lever system, this scale ensures stable, repeatable weighing of lightweight dry bulk solids.
Industry Applications
Suitable for high-accuracy inventory control and totalization of products.
Energy & Building Products: coal for blending, bioenergy pellets, cement raw feedstocks, wood products
Chemical & Industrial: granular fertilizers, specialty chemicals, plastics resin pellets, steel or iron ore fines

Core Technologies
FMSS™: Force Measurement Suspension System
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.
Key Benefits
of Thayer Scale’s Model 6RFS-6/8 High-Accuracy Conveyor Belt Scale
🎯 + 🛡️ Rugged. Accurate. No Compromise.
Achieve accurate weighing down to 0.100% even under heavy loads and demanding operating conditions.
🎚️ 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. Thayer Scale developed and patented the first automatic calibration system in 1971.
⚖️ A Winning Combination
Thayer Scale’s RF belt scales with FMSS mass-counterbalanced technology typically ensures better than 80% load cell utilization.
🔁 Approach-Retreat Weigh Bridge Configuration
Unlike conventional single-idler belt scales, multi-idler configurations (four-, six-, or eight-idler), our approach-retreat design enables true commercial-grade accuracy.
