If you want to know exactly what power your machine has
The Maihak shaft power meter is designed to measure the shaft speed and shaft torsion of sea-going vessels with highest accuracy and repeatability
Hoppe offers a very compact and precise power measurement system that meets all requirements regarding upcoming emission savings. It is also the basis for the digitalisation of a fleet and for performance monitoring


Measuring Solutions
Maihak Shaft Power Meter
- System with highest measuring accuracy (< 0.5% at all load levels)
- Calculates averages per hour, per day, and for a user-defined period
- Generates „heavy run alarm“ or „torque alarm“ with respect to the customer‘s settings
- Calibrated sensors with self-validation by software in operation
- Maintenance free and easy calibration by crew
- For solid and hollow shaft sizes > 150 mm ø and speed up to 800 rpm
Measuring Solutions
Measuring Principle
- Based on two acoustic vibrating wire sensors
- The sensors operate with a natural frequency of 600 Hz
- Due to their orientation, one sensor is stretched and the other is compressed when the shaft is twisted by torque
- In addition, the shaft rotation is measured with a gyroscope, an accelerometer and a Hall sensor
- The product of the mechanical torsion and the shaft speed is the shaft power
- The system is delivered fully calibrated from the factory
