Kyma Shaft Power Meter

Measurement of torque, power and revolutions

The Kyma Shaft Power Sensor measures shaft torque and thrust* using the strain gauge technique. The instrument consists of an aluminum ring clamped onto the shaft, a stationary unit located next to the shaft and a terminal junction box for signal and power connection.

The following propulsion data are recorded by the Kyma Shaft Power Sensor and presented on the Display Unit:

  • Power
  • Rpm
  • Torque
  • Thrust*
  • Total Energy Power
  • Total revolutions

* option

Key Features


As a maintenance-free solution, a zero calibration is the only recommended action to be done on the Kyma Shaft Power Sensor. It is a very easy operation that takes ship staff approx. 10 minutes once every 6 months or so.

Overload Protection

Early warning signals provide a further benefit for the continuous monitoring of propulsion components. These can indicate the overload stress on components and thus prevent an unexpected breakdown. Optimum operation without overloading can also prolong the operating life of components, giving better total economy and improving return on investment.
