摘要： In a strain measuring device employing a magnetic permeability detector means to detect an amount of strain in a passive member as changes of magnetic permeability in a magnetostrictive layer, a magnetic shielding layer is formed on the surface of the passive member, and the magnetostrictive layer is formed thereon so as to lessen the adverse effects of the passive member caused by the magnetic characteristics of the passive member in strain measurement, that is, to reduce measurement errors. Alternatively, a magnetostrictive layer is formed on the surface of the passive member, or a magnetic shielding layer is partially formed on the surface of the passive member of a soft magnetic material with high permeability, so as to lessen the influence of the passive member caused by thermal stresses of the passive member in strain measurement, that is, to reduce measurement errors. Further, there is provided a strain measuring device which facilitates formation of the magnetostrictive layer.

摘要： A strain sensing apparatus includes a pair of magnetic layers disposed on a shaft to which an external force is applied to cause strain in it. The magnetic layers have magnetic permeabilities which change in opposite directions in response to the strain in the shaft. A sensing coil is disposed to face the magnetic layers with a spacing disposed between the coil and the magnetic layers. An exciting AC voltage is applied across the sensing coil. A change in self-inductance of the coil caused by the permeability changes of the magnetic layers due to the shaft strain is derived as an electrical signal representative of the magnitude of the shaft strain.
