ABSTRACT:
A device for measuring the weight and torque on bit while drilling includes an outer bored cylindrical sleeve coaxially connectable into a drill string above a drill bit and an inner bored cylindrical sleeve welded coaxially within the outer sleeve. Strain gages located on the exterior surface of a necked-down section of the inner sleeve are isolated in an ambient pressure environment within annulus between the sleeves. Temperature compensation is accomplished by resistance temperature detectors sensing temperatures at the exterior surfaces of the respective sleeves.
