Article by Thayer Scale-Hyer Industries, Inc.: NTEP Certified Conveyor Belt Scales

Thayer Scale-Hyer Industries, Inc. (United States) - All Thayer Scale NTEP Certified Conveyor Belt Scales are designed to deliver exceptional stability and accuracy for use in applications requiring verifiable accuracy. They are recommended for applications requiring commercial certification for billing purposes. These Belt Scales have been proven in service demanding ±0.125% accuracy through independent certification.

The weigh bridge features exclusive rocking flexure suspension in an approach-retreat 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.

Benefits of the design:

• Use of FMSS technology in the suspension system provides flexibility to use LVDT or Strain Gauge Load Cell options
• Weigh bridge with secondary lever system to mass-counterbalance the dead load (idler support frame, idlers, belts) and minimize loading on the suspension pivot
• Patented RF Flexure Suspension 
• The industry’s highest load cell utilization factor, “NAR” Belt Scales with FMSS Force Measurement Suspension System mass counter balance technology assures better than 80% Load Cell Utilization
