Option: Double bridge
The load cells are equipped with a second strain gauge bridge. The technical specifications
correspond to the previously mentioned options. Metrologically, there are two independent
measurement circuits that are connected to two different transmitters. Mechanically, they are
treated and installed as a load cell.
