The Thayer Model RF-ALA Conveyor Belt Scales are Ideal for Biomass Energy Applications

Available with 2, 3, 4, 6, and 8 idlers, the RF-ALA conveyor belt scales were specifically designed for high accuracy (1/10 to 1/2% typical) inventory control and throughput totalization of light scale loading applications such as Biomass, wood chips, saw dust, tobacco and land refuse.

Superior Performance for Light Load Applications

THAYER’s Models LLRF, RF-ALA and RF-ARLA Conveyor Belt Scales are specifically designed for high accuracy (1/10% to 1/4% typical) inventory control and throughput totalization of light scale loading applications such as Wood Chips, Saw Dust, Tobacco and Biomass.

THAYER’S Belt Scale weigh bridge features exclusive rocking flexure suspension in the approach or 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.
