Abstract
A strain gage transducer system, such as a load cell based weighing system, is protected against moisture related errors by an electrically conducting guard circuit for terminals and other parts subject to wet or humid conditions. The guard circuit is connected to an electrical potential close to a potential of signal terminals in a strain gage bridge, for instance to a center tap in a power supply for the strain gage bridge.
