ABSTRACT:
A strain sensor device is disclosed for attachment to a structural member for measuring strains experienced by the member along a strain axis. The strain sensor device comprises a tensile strain member secured to the structural member generally parallel to the strain axis. Two strain gages are secured to the tensile strain member, one of the strain gages being longitudinally oriented with respect to the strain member to experience longitudinal strain and the other of the strain gages being transversely oriented with respect to the strain member to experience Poisson strain. The two strain gages comprise a strain gage bridge circuit for generating electrical signals proportional to strains sensed in the structural member.
