A strain sensor device for measuring tension on a web or strand member including a frame member, a shaft member extending from the frame member and having a web or strand engaging member mounted thereon, the strain sensor device supporting one portion of the shaft on the frame member. The strain sensor device includes a block member having spaced and opposed first and second wall portions located to be arranged substantially normal to the axis of the shaft, the first wall portion being connected to the frame member and the second wall portion being connected to the shaft member, spaced third and fourth wall portions on the block member extending between and integrally connecting the spaced first and second wall portions, at least one of the third and fourth wall portions having a stress concentrating area capable of deflecting under load on the shaft member produced by tension on the web or strand member, strain sensing transducers located on the third wall portion adjacent to the stress concentrating area for producing the response representative of the tension on the web or strand, and a member mounted on one of the first and second wall portions and extendible into spaced relation to the other of said first and second wall portions to limit the amount of possible relative movement therebetween.
