<p>The device has a sensor coil (30) arranged on a sensor rod for the evaluation of a varying magnetic field dependent on drive parameters e.g. torque. A rotatable shaft has a magnetized region in its inner wall side with the function of a permanent magnet and provided within the area of the coil. The magnet works together with a stationary sensor coil to sense the parameters. A bearing supports the rod directly at a section of the coil. The sensor rod consists of worm gear for supplying the lubricating oil within the borehole to a torque input side.</p> |
