Abstract: An electrical resistance strain gage includes a uniformly distributed electrical resistance of the active measuring area and a discrete electrical trim resistance within an active measuring are. The trim resistance may include an electrical conductor in an electrically parallel circuit such that the electrical conductor may be selectively electrically removed from the strain gage to trim the electrical resistance of the strain gage. The trim resistance does not modify the active strain sensing area or uniform grid length.

Abstract: A methodology for selecting and properly placing foil strain gages on a transducer in a Wheatstone bridge, which provides a more consistent creep response, especially when the transducer temperature is changed. A transducer includes a counterforce subjected to a predetermined physical load that provides tension and compression strains (positive and negative, respectively). The transducer also includes a plurality of strain gage grids that are operatively attached to the counterforce in the tension and compression strain areas of the counterforce and generate electrical signals. The plurality of strain gages are electrically connected in a Wheatstone bridge circuit where their electrical signals due to creep are cancelled.
