Abstract
A centering device is connected to a rotating sensor assembly located at the bottom end of a tool string. The device comprises a centraliser with a plurality of arms spaced circumferentially apart around a longitudinal central axis of the device, and a shaft with a mount for fixing the shaft to the rotating sensor assembly. The shaft extends below the rotating sensor assembly, and the shaft and rotating sensor assembly rotate together on the longitudinal central axis. The centraliser is rotationally mounted to the shaft to allow the shaft to rotate within the centraliser and with the centraliser positioned below the rotating sensor assembly.
