ABSTRACT OF THE DISCLOSURE A hook load measuring system for improving the sensitivity of such measurements in deep-well-drilling operations. It employs a transducer actuated by the hook load and an output signal from the transducer that covers the full range of hook-load variation. There is an ar- rangements for nulling the signal at any given setting, and then for measuring change in a predetermined direction with greatly increased sensitivity. -I-
