Conveyor Belt Scales
Thayer Scale offers Model NAR Belt Scales designed to deliver exceptional stability and accuracy for use in applications requiring verifiable accuracy. Certified by the National Type Evaluation Program (NTEP), the Model NAR is recommended for applications requiring commercial certification for billing purposes, and has been proven in conditions demanding ±0.125% accuracy through independent certification.
The Model NAR Conveyor Belt Scale’s weigh bridge features exclusive rocking flexure suspension in the approach-retreat configuration. Measurement sensitivity is high, deflection is low, and the single 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 – a process decidedly better than belt scale designs supporting full tare load on the load sensors. In addition, the belt scale’s superior zero stability typically requires no K-Factor adjustment between certification tests – greatly reducing test expenses and down time. The NAR Belt Scales come in 4, 6 and 8 idler design, 24” to 96” width, and a maximum capacity of 10,200 TPH.
