Torsional Vibration & Torque Measurement

Enhancing the reliability, safety, and efficiency of vessel propulsion systems requires a comprehensive understanding of torsional vibrations and torque dynamics along the propulsion shaft line. Our cutting-edge technologies and expertise at Info Marine empower vessel operators with precise measurements and actionable insights.

Torsional Vibration Measurements

Torsional vibration, the oscillation or twisting of the propulsion shaft during torque transmission, is a critical aspect of propulsion system dynamics.


  • Monitoring Techniques:

Convert virtually any drive shaft into a rotating torque sensor by simply mounting the wireless torque transmitter, battery, and a torque-sensitive strain gauge to the shaft. 


  • Causes of Torsional Vibrations:

Identifying factors such as uneven engine firing, problems with torsional vibration damper, sudden load changes, or propeller cavitation that contribute to torsional vibrations is key to maintaining a robust propulsion system.


Torque Measurements

Torque measurements involve assessing the rotational force applied to the propulsion shaft, offering insights into power transmission dynamics.


Importance of Torque Data:

Monitoring torque is critical for preventing overloads, minimizing wear and tear, and maximizing the efficiency of the propulsion system.
