摘要： PROBLEM TO BE SOLVED: To attain high sensitivity, and to improve sensor precision.
SOLUTION: This load sensor comprises a body part strained by a load, a plating film 2 formed to be in close contact to an outer circumference part of the body part, and of which the magnetic characteristic is varied in response to a strain of the body part, a magnetic substance yoke 3 constituted to form a closed magnetic circuit with the plating film 2, and a coil 4 wound onto the magnetic substance yoke 3, and for converting a change of the magnetic characteristic into an electric inductance after saturating magnetically the film 2. A direct current magnetic field is impressed at a level at least larger than that of coercive force of the film 2, and up to reach to saturated magnetic flux density, from the coil 4, so as to fix an operation point to residual magnetic flux density.

摘要： PROBLEM TO BE SOLVED: To provide a load sensor easy to be handled in both a structural aspect and a using aspect, and capable of detecting a load precisely and reliably.
SOLUTION: This load sensor is provided with pressing body parts for push having a flat plane press-contacting with a pressurizing part of a sensor part 4, and a pair of parallel load impressing components 2 having integrally a projected part projected outwards therefrom along one axial direction, as load detecting components onto the existing sensor part 4, to impress the load to the pressurizing parts in the opposed planes of the sensor part 4 in parallel along the one axial direction (load impressing direction P), and the sensor part 4 and the pressing body part of the each parallel load impressing component 2 are movable along the one axial direction by a sheath component 1 of a nonmagnetic material to be stored engageably. The sheath component 1 has in a local part of its side face a window for pulling out lead wires 3 in both end portions of a coil to an outside in the sensor part 4, and exposes in its both end face sides the projected parts of the paired parallel load impressing components 2, and end face side local parts of the pressing body parts provided therewith.
