Abstract
PURPOSE:To simultaneously measure the values and directions of the peripheral stress and axial stress of a shaft to be measured by transducing the stress of the shaft to be measured into magnetic strain and transducing the magnetic strain into the variation quantity of inductance by 1st and 2nd coils. CONSTITUTION:First and second segments 7 and 8 are provided on the peripheral surface of the shaft 6 in a spread shape at a necessary angle theta. The 1st and 2nd segments 7 and 8 transduce the stress of the shaft 6 into the magnetic strains. Then 1st and 2nd coils 9 and 10 transduce the magnetic strains sigma1 and sigma2 of the 1st and 2nd segments 7 and 8 into the variation quantities of inductance. Then an arithmetic means calculates the peripheral stress and axial stress of the shaft.
