ABSTRACT:
Disclosed is a device for detecting tension in a running yarn which comprises a U-shaped primary core which has primary windings wound thereon and which is capable of being electromagnetically excited by means of an alternating current; a U-shaped secondary core which faces the primary core with a small air gap therebetween and forms a main magnetic circuit therewith, and which has secondary windings wound thereon for interlinking the secondary core with the main magnetic circuit; a rotatable member consisting of a shaft which is rotatably supported on an axis and a circular disc of a non-magnetic material secured to the shaft, and then swung between the air gaps; and a magnetic flux by-passing member fastened to the circular disc and consisting of a thin plate of a ferromagnetic substance which has a crescent shape formed from a circular disc having a large diameter and a removed circular opening having a small diameter, which opening is removed from the disc. The device has a very wide linear range and is preferable for detecting a running yarn tension.
