We manufacture weigh scales and have installed a number of systems till 30 Tons capacity. We have calibrated these with water to achieve desired result. I am now interested in bidding for a project where about 20 tanks of 500 Tons each are to be installted. Some would be with 4 loadcells and some with 3 loadcells + 1 Dummy cell
However i do not know how to calibrate these. Material substitution does not seem practical since it involves a very large volume, which may not be possible. Intital calibration is usually achieved after loading material atleast 2-3 times so weighbridge based transfer would also lead to problems of storage
While calibrating at lower load is an obvious solution, there is a chance of linearty error since capacities are high. I would like to know how other people have solved this problem or of the best possible solution
