SL-RC3 Compression load cell
Single column compression load cell – the SL-RC3. Compact and yet very robust the SL-RC3 is available in a very wide range of capacities from 7.5t through to 100t. The rocker column design ensures that the optimum weighing accuracy is achieved when subjected to scale deck movement. Fully hermetically sealed and constructed from stainless steel the SL-RC3 is a more economical solution to the RC1 load cell.
