The TVSTM system accurately measures speed, torque, and torsional vibration.

Accurate shaft speed measurement

Hold your system accountable to the speed limits. Speed measurement helps you ensure that your system is operating as intended. Speed is critical in a variety of applications across industries.

  • In power generation speed changes can lead to fluctuations in frequency of the AC power produced.
  • In films and paper manufacturing variations in roller speed can lead to inconsistent product dimensions and scrap.
  • In automotive and industrial environments variation in speed can be an identifier of unbalance in the system.

Taking accurate real time speed measurements can allow you to automate system shut down before failure, identify out of tolerance product, and account for variation in your manufacturing system.


Torsional Vibration Measurement

Torsional vibration measurements help you avoid downtime and surprises.

Torsional vibration is the measurement of angular vibrations of an object assessed by measuring variations in shaft speed at high resolution.  Torsional vibration usually occurs about the axis of rotation and can be induced by variations in shaft load, unbalance, or bearing degradation, or other undesirable characteristics of the drivetrain.

Torsional vibration measurements help identify issues in rotating equipment in lieu of scheduled maintenance intervals or prior to catastrophic failure.  Foreknowledge of a problem before failure and avoiding premature maintenance, results in less down-time and lower maintenance costs.


Torque Measurement

Torque measurement helps you plan your machine preventive maintenance intelligently.

Accurate torque measurement is critical to understanding the health of the rotating system. Torque monitoring over time can alert the user to system aberrations or over-torque conditions that are leading indicators of system failure.

Additionally, combining the TVS torque and speed measurement results in a high accuracy measurement of shaft power and enables precise calculation of system efficiency.


Using TVSTM to Measure Speed, Torque, and Torsional Vibration

These measurements can be achieved several ways, but the greatest advantage of our optical system approach is that the sensor does not need to make contact with the shaft in order to give high accuracy measurement. Rotating systems are sensitive to balance and loading conditions, by opting for a non-contact sensor you avoid these potential risks.

Additionally, installation of the system can be done both retroactively on existing systems or designed into the system upon conception. The ease of installation combined with the minimally invasive aspect of the sensor system makes it an ideal measurement tool for a variety of applications and environments.
