ARCH’s patented dual-ended load cells, which mount directly to the idler, are the reason that you can now rely on accurate data (up to +/- 1/2%) every day without recalibration. The dual load cells work opposite each other to neutralize the natural lateral and vertical movements of your conveyor belt. As one end is pushed down by a force, the other is naturally lifted by that same force; any movement is cancelled out.
It is also the only belt scale that’s calibrated with the conveyor stopped, giving you a true zero reading. ArchWeigh® load cells are designed specifically for use on conveyor scales and are the only load cells to be patented since 1970. The load cell’s unique design allows it to use a positive/negative response to account for normal conveyor variances.
