How do vibrations occur on machines?
Vibrations originate in in- and out-movements of machines and rotating machines and machine components, for example of pistons, compressors, rotors, shafts and rollers, as well as gearboxes and pumps. The amplitude and the frequencies depend on the natural frequencies and stiffness. Additional shocks that are caused by damage to individual components are additionally provoking vibrations on machines. Based on their amplitudes and frequencies, machine and component faults can be detected and localized, for example: unbalance, rolling bearing damage or misalignment.
Which sensors are needed for a measurement?
- Speed sensors
- Speed sensor with pulse output e.g. 360 pulses per revolution, for connection to an imc incremental encoder input (counter).
- Speed sensor outputs proportional voltage or current (4...20 mA), for connection to an analog input.
- IEPE sensors for acceleration, vibration velocity, displacement sensors, microphones, forces, pressures.
- All sensors must be acquired time-synchronized and can then be calculated and displayed in the online imc WAVE.
