<p><P>PROBLEM TO BE SOLVED: To provide a clamp sensor allowing accurate measurement free from variations in measurement accuracy while excelling in operability. <P>SOLUTION: In this clamp sensor 1, a measured conductor 50 is passed therethrough inside an approximate ring shape in a closed state wherein ends 21a and 21b of approximately circular arc-shaped, pair-forming, fixed and movable sensor arms 4a and 4b abut on each other to form the ring shape. A movable body 3 is turnably journaled to a shaft 9 with a body 2 and the movable body 3 crossed in a scissor-like manner, the body 2 comprising a fixed lever 5a integrally joined to a fixed sensor arm 4a while the movable body 3 comprising a movable lever 5b integrally joined to a movable sensor arm 4b. The movable lever 5b is urged by a torsion coil spring 8 locked by the two levers 5a and 5b in a direction causing the ends 21a and 21b of the two arms 4a and 4b to part from each other into an open state. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
