  • Hydrostatically compensated deep sea probe with shear strain gauges
    Patent number: 7810381
    Abstract: A hydrostatically compensated soil resistance probe includes a cylindrical body having a distal tip for insertion into a material, a plurality of load gates for transitioning an axial load on said cylindrical body to a shear load, and a plurality of shear load sensors to measure a transverse loading on said probe due to an axial loading. The axial loading can be the result of the resistance on the probe tip to the insertion of the probe in the soil, or the frictional forces acting on a friction sleeve as the probe passes through the soil.
