PBW2-2Precision belt weigher · two load cell, two idler

Two weigh idlers on a centrally floating, two load cell frame: a longer weigh span that holds ±0.50% of actual weight at belt speeds up to 3.0 m/s*, twice the speed of the PBW2-1 at the same class. Rated to 6.0 m/s, for belts from 750 to 2,000 mm. Australian designed and made.

The PBW2-2 weigh frame

A centrally floating weigh frame on two stainless S-type load cells, carrying two weigh idlers. The longer weigh span holds ±0.50% of actual weight at twice the belt speed of the PBW2-1. Shown in hot-dip galvanised mild steel in the conveyor; stainless steel when needed.

The PBW2-2, step by step

From bare frame to running conveyor

Every part of a PBW2-2 installation, in the order it goes together. Accurate Industries supplies the lot: the weigh frame, weigh idlers, speed sensor and off-scale idlers, plus the integrator and calibration.

PBW2-2 galvanised weigh frame with two load cells

1. The weigh frame

The galvanised, centrally floating weigh frame on its two S-type load cells.

2. Weigh idlers, on the stringers

Two weigh idler frames on the scale, bolted between the conveyor stringers.

3. Off-scale idlers

Standard idler frames either side of the scale, so the belt runs true through the weigh area.

4. Belt fitted

Carry and return belt in place: the conveyor as it runs empty. Add the speed sensor and integrator and it is weighing.
