Thayer Scale Belt Scales: Commercial Grade and Certified Quality Conveyor Belt Scale

February 28, 2022

Thayer Scale’s conveyor belt scales & conveyor weighing systems are designed for a range of accuracies: high accuracy loading and unloading systems, custody transfer and NTEP-approved versions (0.10% – 0.125%), inventory control and processing needs (0.25% – 0.5%), and various stone and aggregate applications (0.5% to 1%). Customers in fertilizer, mining, ore, copper, and coal industries utilize our conveyor belt scales in severe applications and in some of the harshest manufacturing environments. Other industries, including pulp and paper and tobacco processing, use our belt scales for light-loading applications. These examples illustrate how our standard designs can support a wide range of belt scale applications with only minor modifications.

Thayer offers many special configurations with their conveyor weighting system (conveyor belt scales) and scale prices; designed for light-scale loading of materials such as biomass, wood chips, saw dust, tobacco and MSW. We build 1, 2, 3, 4, 6 and 8 idler belt scales supporting belts from 14 to 96 (and over) inches wide.

Thayer Scale’s conveyor belt scales offer:

A weighbridge that features an exclusive rocking flexure suspension system for both Approach and Approach/Retreat configurations

High measurement sensitivity, low deflection, and a single load cell that is isolated from significant error-producing forces including:

  • Extraneous lateral forces
  • Off-center loading
  • Foundation distortion
  • Inclination holdback forces
  • High sporadic shocks and overloads

Conveyor Belt Scales – Mass-counterbalanced tare loads to create a high signal‐to‐noise ratio in weight-sensing

Proven immunity to zero biases and shifts, resulting in a stable scale zero—the foundation of all continuous weighing devices (conveyor belt scales)

Test weights to physically exercise the scale lever (we avoid resistor calibration, which can mask systemic errors in the belt scale installation)

A fixed-circumference precision belt-travel sensing wheel simply mounted to the conveyor stringers using four bolts
