The tension of flexible linear material such as cables, strands and the like can be measured with improved accuracy with the tension measuring device and method of the present invention. The measurement is effected by a tension measuring device having an engaging means, a bending means, at least one displacement means, at least two sensing means, and one or more indicating means. The engaging means contacts the flexible linear material and in conjunction with the bending means provides a fixed angle of bending to the linear material. The one or more displacement means are associated with the engaging means and are displaced in response to the fixed bending angle of the linear material. The two or more sensing means are positioned to each other at any nonlinear angular relationship in sensing engagement with the displacement means. The sensing means initiate signals in response to the displacement of the displacing maans. The signals are conveyed by the conducting means to the one or more indicating means which provides the output from the signals of the sensing means as conditioned, scaled of magnitudes for tension and coefficient of friction. An example of the more than one displacement means is a block having a planar configuration with a top and bottom surface and an outer and inner portion. The outer portion is comprised of a displacing beam and a second beam connected together at their ends by two connecting beams. The inner portion within but spaced apart from the outer portion has an attachment beam for attachment to the outer portion and a displacing beam connected to the attachment beam by two connecting beams, where one is at each end of the displacing beam. Each connecting beam of the inner and outer portion has at least one flexural pivot means. |
