A light source providing intermittent light flashes permits a user to visibly discern the relative rotational position of the reference marks to one another, and thereby determine the torque applied to the coupling. | 12-31-2015 |
20160046458 | ANTI-ROTATION BASED TORQUE MEASUREMENT DEVICE - Apparatus and methods for web tension control are provided. In an example, an apparatus can include a tension beam configured to deflect in a predictive manner when under a force load, a first shaft directly coupled to the tension beam and configured to mechanically interface with a torque device, a second shaft directly coupled to the tension beam opposite the first shaft and configured to interface with a structural member of a web machine, and a strain gauge coupled to the tension beam and configured to provide an electrical representation of the force load. | 02-18-2016 |
20160084721 | SENSOR ARRANGEMENT STRUCTURE - A sensor arrangement structure includes an output shaft provided with a disc portion at a leading end portion thereof. An output shaft cover has an inner surface portion disposed along and close to the disc portion. The disc portion is provided with ribs, the ribs extending in a radial direction of the disc portion while protruding toward the inner surface portion. A detector is disposed more inward in the radial direction of the disc portion than the ribs. | 03-24-2016 |
