LEMAG Shaftpower

LEMAG Shaftpower® is a permanent shaft power measuring system, which displays the actual effective engine power output at any time. The shaft twist is
measured between a defined distance on the shaft, using two highly accurate linear precision position encoders. The measured data is digitalized in the
rotating unit and transmitted contact-free to the processor unit.

The measuring system:

improves efficiency
protects from overload
protects from breakdown
optimizes fuel consumption
controls the effect of energy saving devices


The measuring system includes the following features:

• touch screen operated
• contact-free sensors
• maintenance free design
• easy to operate
• different measuring units
• user-friendly zero calibration procedure
• display of actual shaft power, RPM, torque and average power
• comparison with reference propeller curve
• RS-485, NMEA 0183 serial interface
• optional analogue outputs
• optional overload warning and alarm
• backlit touch-screen
• optional bridge display
• direction of rotation
