  • Apparatus for measuring axial stresses on a rod
    Patent number: 5327786
    Abstract: Apparatus for measuring axial bending or tensile stresses on a rod (1).A ring (10) carries at least one sensor or transducer (15). A ring (11), parallel to the ring (10), serves as a magnetic target. The rings are formed by two substantially semicircular, dismantlable halves. The measurement consists of estimating the width of the gap (12) between the rings (10 and 11). The sensors (15) can be of the magnetic reluctance type.Application to the measurement of stresses in sliding rods of certain safety taps, cocks or valves.
