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