FIELD: geophysical researches in wells. SUBSTANCE: device has a supporting frame, lever, force converter and three jockey rollers one of which is noncircular. Cable passes major part of its motion at small angle of bending and varying electric signal forms at output of force converter. Signal maximum characterizes cable tension, number of maximum characterizes depth, and frequency characterizes speed of cable motion. EFFECT: higher accuracy of measurement and reduced wear of cable. 1 dwg
