Abstract
A bottom hole assembly (BHA) of a drill string includes a chassis, a plate coupled to the chassis, and a strain gauge coupled to the plate. The strain gauge is used to output a signal associated with a deformation of the plate. The plate and chassis may be included within a collar that experiences strain, and deformation of the collar may be translated to the chassis and the plate. The plate may experience strain in the form of torsional bending, in-plane bending, out-of-plane bending, axial tension or compression. The plate may include or be coupled to an electronics board that has strain gauges to measure different types of strain in isolation from other types of strain.
