Abstract:
A tension measuring device comprising:(a) an elongated body having two ends, said elongated body further comprising a hollow interior comprising a first interior wall and a second interior wall, wherein the first interior wall and the second interior wall oppose each other; (b) a deflection block secured to each end of the elongated body for holding a line spaced apart from the elongated body; (c) a clamping mechanism between the deflection blocks from clamping the line to the elongated body wherein increased tension in the line will bend the elongated body; (d) a first strain gauge element attached to the first interior wall and a second strain gauge element attached to the second interior wall, wherein the first strain gauge produces an output signal proportional to the bending tension of the first interior wall of the elongated body and the second strain gauge produces an output signal proportional to the compression of the second interior wall; and (e) a linearizing signal device connected to the first and second strain gauge elements for processing the output signal and for providing a readable output representative of the tension on the line.
