    摘要： To determine whether or not a rivet has been delivered to, and is properly centered between a pair of complementary recesses provided in the fingers of an automatic riveting machine, a pair of strain gauges are operatively associated with the rivet holding fingers, the strain gauges being incorporated in opposite sides of a balanced, bridged circuit which is connected to actuate, selectively, a plurality of detectors, each detector, when actuated, indicating a relative separated condition of the rivet holding fingers.
