Torque Measuring System TORXmeter®

Torque Measuring System TORXmeter



The TORXmeter® is a permanent shaft power measuring system basically designed for seagoing vessels, but may be used also for other engine-driven applications. Provided data are vital for evaluating engine performance in relation to power consumption (burning of fuel), thus helps to improve engine efficiency and to reduce fuel costs.

The TORXmeter® is easy to install and requires no electronic/electric parts on the shaft. Only two magnetic sensor belts in a distance of 1.5 to 2 m have to be installed on the shaft. The system works contact free, which makes it rugged and more durable than competitive systems.

Simple installation and calibration makes presence of a service technician unnecessary and is usually done by the vessel’s crew.

Data transmission to additional systems, e.g. vessel’s automation system, can be easily done via 4 to 20 mA outputs and NMEA Protocol (RS485). Installation of several repeater displays (engine control room, bridge) is possible.

The intuitive touch screen interface of the terminal box allows easy operation, permanent display, and automatic reports of following values:


  • Shaft power (kW)
  • Shaft speed (RPM)
  • Torque (kNm)
