Thayer Scale-Hyer Industries, Inc. (USA) - THAYER “NAR” Belt Scales are designed to deliver exceptional stability and accuracy for use in applications requiring verifiable accuracy. Model “NAR” is recommended for applications requiring commercial certification for billing purposes.

These belts have been proven in service demanding ±0.125% accuracy through independent certification. The 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, orders of magnitude better than belt scale designs supporting full tare load on the load sensors.

Superior zero stability and typically requires no K-Factor adjustment between certification tests which greatly reduces 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.
