SYSTEM FOR INTEGRATED EARTH PROBING Russian patent published in 2008 - IPC E02D1/00 

FIELD: constructional engineering.

SUBSTANCE: invention refers to constructional engineering, namely to systems for detecting physical and mechanical properties of earth at geological engineering survey. The system for integrated earth probing contains the body with axial cone and longitudinal blades, threshold pressure transducer mounted in casing hermetic cavity, and thrust and torque converter designed as two string transformers with strings connected with in-body resilient member and electromagnetic pickups cabled to converter recorder. Strings of converters are located in intersecting planes inclined towards the system longitudinal axis at angles α and -α, and points of attachment in upper and lower horizontal profiles of resilient member being symmetric relative to profile centres of resilient member.

EFFECT: increased accuracy of torque measurement.
