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 digitalization 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
