Model NAR Belt Scales are designed to deliver exceptional stability and 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-percent accuracy through independent certification, notes the manufacturer. The 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. 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-in. width, and a maximum capacity of 10,200 tph.
