Abstract

PURPOSE:To facilitate the detection of a clamping load with high accuracy and high stability, by using a ring-shaped main iron core containing a ring-shaped groove, a coil which measures the magnetic properties and an auxiliary iron core which is fitted to the main iron core, respectively. CONSTITUTION:A load detecting sensor 5 contains a ring-shaped groove which is concentric to the center of a ring-shaped main iron core 1, and a coil 3 for measurement of magnetic properties consisting of an energizing coil and a magnetic flux detecting coil is stored in the ring-shaped groove. A ring-shaped auxiliary iron core 2 is stacked on the core 1 to form a magnetic circuit. Furthermore, the concave core 1 is fitted to the convex core 2 at the outer circumference side of the junction face of the cores 1 and 2. Thus the clamping load can be easily detected with high accuracy and high stability.
