ABSTRACT:
A strain gage includes four gages that constitute a bridge circuit, and at least one resistance device which is used to adjust the offset voltage of the bridge circuit formed by the four gages. The resistance device is disposed on the strain gage between one of the gages making up the bridge circuit and a terminal thereof. Finally, each resistance device disposed on the strain gage has a series of resisting elements which vary in size and which are connected in parallel fashion.
