Vibration measurement for machine monitoring
In machine operation, unwanted vibrations are usually caused by mechanical imbalance, misalignment of components or material wear. In the worst case scenario, this can lead to expensive downtime. In some applications, however, vibrations are also generated intentionally, for example in vibratory conveyors and vibrating screens. In any case, precise measurement and analysis of the pulses is required in order to detect faults at an early stage.
Different measured variables are recorded depending on the area of application:
- Vibration acceleration (without integrator), particularly suitable for higher-frequency vibrations, e.g. on roller bearings or gears and for shocks
- Vibration velocity (integrator), particularly suitable for machine condition monitoring according to ISO 20816
- Vibration displacement (double integrator), particularly suitable for measuring the vibration amplitude on vibrating conveyors, vibrating screens and sifters
