A moving web tension monitoring apparatus (12) of easily fabricated, relatively inexpensive and easily assembled construction comprising a cantilever mounted strain beam element (30) coupled at the flexurable end thereof through a rigid coupling to one end of a support shaft (20) for the web supporting a guide roll (18). A twin beam type transducer (A), having strain gauges (200, 206) at the flex points of the beams, is coupled to the shaft (20) supporting the moving web. The strain gauges (200, 206) are located and electrically connected to measure the radial forces applied to the shaft. A shaft coupler (110) connects the shaft to a bearing in the transducer (A) to reduce slippage of the shaft. The transducer is designed to be easily adjusted so that the forces applied to the shaft are accurately detected. The components of the transducer are also adjustable to alter the rigidity and/or resonance frequency of the transducer.
