Abstract: A moving web tension monitoring apparatus of easily fabricated, relatively inexpensive and easily assembled construction comprises a cantilever mounted strain beam element coupled at the flexurable end thereof through a rigid coupling to one end of the support shaft for the web supporting guide roll. A twin beam type transducer having strain gauges at the flex points of the beams is coupled to the shaft supporting the moving web. The strain gauges are located and electrically connected to measure the radial forces applied to the shaft by the web independently of the length of the shaft.

Abstract: A load cell includes a strain inducing element having a fixed rigid body fixedly secured to a base support, and a plurality of transverse beams spaced one above the other and connecting the fixed and movable rigid bodies together. Each of the transverse beams has first and second strain generating areas defined therein in spaced relation to each other at respective locations adjacent the fixed and movable rigid bodies. A bridge circuit for outputting a load signal of a magnitude proportional to strains generated at the strain generating areas includes strain gauges for detecting the strains generated at the strain generating areas, adjusting elements for adjusting a balance of the bridge circuit, and lines connecting them together. A circuit portion of the bridge circuit which includes at least the strain gauge and some of the lines is formed in a predetermined pattern on one surface of the strain inducing element so as to straddle between the first and second strain generating areas. Not only is the circuit portion symmetrical with respect to a point intermediate between the first and second strain generating areas, but also the strain inducing element has left and right portions, including the fixed and movable rigid bodies, which are symmetrical to each other.

Abstract: A drag balance for measuring drag forces on a model is described which mos within a hollow region of a streamlined strut. The strut is attached to a carriage for towing the model through a medium. The drag balance has a ground frame attached inside the strut and a balance frame attached to the flat plate at the base of the strut. The ground frame and balance frame are connected by flexures which allow only a small amount of movement of the balance frame and model relative to the ground frame and strut in the towing direction. Strain gages are attached to one or more of the flexures to determine the amount of bending in the flexures and thus obtain a measure of the drag forces exerted on the model. Mounting the drag balance within the streamlined strut minimizes turbulence and allows the drag balance to be connected directly to the model at the base of the strut such that drag forces on the model are accurately determined.

Abstract: A shear beam, single-point load cell is provided. The load cell includes a shear beam with a pair of shear strain gauge sensors mounted on opposing sides thereof for measuring strain within a small portion of the shear beam. The strain gauges are isolated within sealed pockets from moisture or harsh chemicals. The use of a shear beam, rather than a bending cantilevered beam of conventional load cells, allows the load cell to be sturdier and more robust than conventional load cells, to thereby measure and detect greater amounts of load. The provision of the strain gauges positioned for measuring strain within a small portion of the shear beam allows the load cell to accurately and precisely measure loads regardless of the mounting position of the load on the load cell. Further, the provision of closely adjacent strain gauges renders the load cells relatively immune to thermal gradients inherent in conventional load cells having widely separated strain gauges. The load cell is relatively inexpensive to manufacture and maintain, and yet provides accurate and precise load measurements.

Abstract: A load cell has a cantilever-type load-sensitive element with an upper beam and a lower beam, each having formed thereon a pair of strain-generating parts which generates a strain corresponding to an applied load. Only one of these two beams has an indented part formed on its surface and strain-detecting elements are attached to its bottom surface at positions corresponding to the strain-generating parts. A moisture-proof sheet is attached to the beam to completely seal the interior of this indented part to protect the strain-detecting elements from humidity and moisture.
