ABSTRACT:
A bolt-on strain sensor includes an L-shaped sensor body having a mounting hole formed at the end of each leg of the L-shaped body and a mounting hole formed at the intersection of the legs. A first strain sensing structure is formed in the sensor body between two of the mounting holes and a second strain sensing structure is formed in the sensor body between the other two mounting holes. The strain sensing structure is preferably a strain gauge instrumented measurement beam connected to the sensor body on opposite sides of the strain sensing region by spaced apart interconnecting members. A printed circuit board on which a plurality of electrical components are mounted is secured to the sensor body with a suitable fastener. A cover is then placed over the sensor body and printed circuit board.
