Hi
We're using Streeter Amet load cells with Hardy 2151 30WC scales
to weigh hoppers with about 2000 kg of material. We have 5 in a row and 4 of them work ok. The second one in has a tendency to drift about 50 kg at times. I checked the shielding from the summing connection to the scale. Its continuous and grounded only at the scale end.
If I hook up a calibrator, the drifting stops. The cabling from the load cells to the summing junction looks premade and very difficult to get into. All 3 channels drift. The shield is not grounded at the load cell end. Any suggestions??
