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.
