ABSTRACT:
A strain sensing device for measuring deformation experienced by a force carrying member. The transducer includes a strain sensing element, terminal blocks, and cable terminal connections all protectively contained within a water and contaminant resistant enclosure. The transducer enclosure includes a tubular sheath within which the sensing element and terminal blocks are housed, and a pair of rubber bushings located in opposed ends of the sheath and each formed with an axial passageway. A ball is tightly held in the axial passageway of each bushing for sealing the interior of the sheath while permitting the direct transmittal of forces to the sensing element via said balls and terminal blocks.
