The contactless measuring system measures elastic compression of the ship’s shaft as well as elastic torsion through the use of high-resolution HD sensor technology. The HD sensors are aligned against a target object and measure here the distance changes in the nanometer range. In addition, built-in temperature sensors support the measurement and evaluation, through internal calculation and calculation of the measured values. A local display shows the measured values (torque, thrust, speed, shaft power) on a display, as the measured values can also be output by connecting to external systems (or 4-20mA outputs). A PC software supports the user in the evaluation and reporting of the measurement results.
