摘要： An apparatus for measuring tension in linearly extended flexible material. The apparatus comprises: a support means; a first member having one end attached to the support means; means associated with the first member for engaging tensioned material to impart a bend thereto, thereby causing strain in the first member, such strain being produced by first and second moments, with the first and second moments being separate moments; and means associated with the engaging means for sensing the strain caused in the first member by only the first moment and for generating a signal responsive thereto as an indication of the tension in the material.

摘要： 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.

摘要： A force transducer having an elongate strain element with a narrowed waist portion formed symmetrically about its longitudinal axis and intermediate its ends to concentrate the applied stress at the waist portion. A hole is formed centrally through the waist portion, the axis of the hole being normal to and intersecting the longitudinal axis of the strain element and strain gages located adjacent the internal perimetric surface of the hole that are responsive to the concentrated stress. The hole may be sealed and isolated from the ambient environment by a readily yieldable plug and electrical outlet which covers the hole.

摘要： A cold rolling mill is described wherein the unstressed shape of metal sheet is continuously sensed during rolling by a plurality of negligible displacement force sensors perpendicularly disposed relative to the pass line at a mill location producing a tensile stress above 4,000 p.s.i. in the metal sheet being rolled. The output signals from those sensors underlying opposite edges of the metal sheet are compared to equalize reduction at the sheet edges while the difference between the force measured by a centrally situated sensor and the average force measured by the sensors underlying opposite edges of the sheet provide a signal indicative of the roll bending force required to produce flat sheet.

摘要： Systems and methods for measuring cogging torque. An example method includes causing an electric motor to rotate in a positive direction, and for given multiple encoder positions of an encoder, determining a first respective motor winding current applied to the electric motor at the given encoder position. Additionally, the method includes causing the electric motor to rotate in a negative direction, and for the given multiple encoder positions, determining a second respective motor winding current applied to the electric motor at the given encoder position. Further, the method includes, for the given multiple encoder positions, determining a respective cogging torque based on a difference between the first and second respective winding currents. And the method includes storing a cogging torque profile for the electric motor in a database based on the determined respective cogging torque for the given multiple encoder positions.
