Thrust-Torque Measuring System EVOthrust®

Thrust-Torque Measuring System EVOthrust



The EVOthrust® is much more than a simple shaft-power system, as it is providing the real efficiency of the ships´ propulsion systems by measuring the ration of the generated engine torque to the propeller thrust.

Our system allows to determine, how much energy is really converted into propulsion of the ship hull and not wasted only in rotation of the propeller.

The thrust-torque measuring system EVOthrust® measures the following key parameters  by using the latest HD sensor technology:


  • Thrust (kN)
  • Torque (kNm)
  • Shaft power (kWh)
  • Shaft speed (RPM), direction of rotation
  • Efficiency factor


The EVOthrust® was developed in a “heavy duty” design, with wireless energy transfer, radio transmission and the output of the measurement results via 4 to 20 mA or RS 485 interface. The measurement values will be shown on a numerical display or by connecting a PC using the supplied PC software. By means of this software the data can be stored and a further analysis is possible.

The EVOthrust® is completely pre-installed in our work shop, allowing an easy installation in a short time.


  • Aided by German state as environmental innovation
  • Revolutionary HD sensor technology, no strain gauges
  • High-definition thrust and torque measurement
  • Contactless transmission of energy
  • Telemetric data transfer
  • No wear and tear
  • Heavy duty design
  • Supports slow-steaming
  • For all shaft diameters (> 300 mm)
  • Supports energy docking
  • Shows thrust, torque, RPM, power, propulsion efficiency continuously


The EVOthrust® is supplied with powerful Windows-based software incl. a reporting function from ship to shore. A history viewer allows comparing measurements before and after dry-docking or engine overhaul.
