Abstract
In accordance with an illustrative embodiment of the present invention, apparatus for use in measuring weight-on-bit downhole during a drilling operation includes tubular telescoping members having resilient means reacting therebetween whereby relative longitudinal movement of the members is functionally relative to axial loading of a drill bit, sensor means mounted on one member and connected by linkage means to the other member for sensing the amount of relative movement, and means providing an elastic discontinuity in said linkage means for substantially isolating said sensor means from vibratory movement of said other member due to the cutting action of the bit.
