Abstract
A pressure compensated sensor assembly for determining loads near a drill bit may include a body member having an inner diameter and an outer diameter, a sleeve member having an inner diameter and an outer diameter, the sleeve member being coupled to the body member, a first gap having a thickness and a length dimension formed between the body member and the sleeve member, and one or more sensors coupled to the sleeve member. The one or more sensors may measure axial and torsional loads on the sleeve member without measuring parasitic strain induced on the body member.
