摘要： 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.
