PBW2-1Precision belt weigher · two load cell, single idler
One weigh idler on a centrally floating weigh frame with two stainless S-type load cells (OIML R60 C3, IP67): ±0.50% of actual weight at belt speeds up to 1.5 m/s*, rated to 6.0 m/s, for belts from 750 to 2,000 mm. Australian designed and made.

The PBW2-1 weigh frame
A centrally floating weigh frame on two stainless S-type load cells, carrying a single weigh idler: the simplest Precision frame, for belts that run at up to 1.5 m/s where ±0.50% of actual weight is needed. Shown in hot-dip galvanised mild steel in the conveyor; stainless steel when needed.
From bare frame to running conveyor
Every part of a PBW2-1 installation, in the order it goes together. Accurate Industries supplies the lot: the weigh frame, weigh idler, speed sensor and off-scale idlers, plus the integrator and calibration.
1. The weigh frame
The galvanised, centrally floating weigh frame on its two S-type load cells.
2. Weigh idler, on the stringers
The single weigh idler frame 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.
