Linear Vibration | Torsional Vibration | |
---|---|---|
Definition | Movement or mechanical oscillation about an equilibrium position of a machine or component | Changes in the relative angular displacement between two points on a rotating shaft |
Sensor | Lateral vibration can be measured mostly using accelerometers | Torsional vibration can be monitored using a sensor such as an MPU, speed sensor, and encoder |
Sensor Location | Very critical parameter. If the site is wrong, there will be lots of false alarms | The sensor is positioned on the rotating shaft |
Repeatability/ Calibration | Often require sensor calibration to ensure accurate and repeatable results | This technique comes with a sensor with a once-in-a-lifetime calibration, i.e., unlimited life with the same accuracy |
Summary | The measurement of lateral vibrations is an indirect measurement of the forces on the component that could fail. | The measurement of torsional vibrations is a direct measurement of the forces on the component that could fail. |
