To greatly simplify the tasks of vibration measurement, frequency analysis and in-position dynamic balancing, the baseline microprocessor-based vibration analyser-cum-dynamic balancer 6050 is designed. Following are some of the technical features of this vibration analyser-cum-balancer: automated full frequency analysis. Its microcontroller scans the entire frequency range looking for spectral peaks; each peak contains valuable information: the magnitude of the peak is the magnitude of the vibration and the frequency is related to the nature of the defect. In case of imbalance being the dominant cause of vibration, a peak is found at the rotational frequency with a magnitude comparable to the overall vibration. In such an event, the next logical step is to balance the rotor in-situ; 6050 also performs the vector calculations required for 1-plane or 2-plane dynamic balancing, giving direct results where correction must be made in amount and angle. With the pc software vscan, the spectra can be quickly transferred to the pc over a serial port. The unit suppliesa statistical routine in which the minimum, maximum and mean of 20 successive readings are reported, for widely varying vibrations as typically found in induction motors; spectra can not only be saved, and printed, but a host of tools allow the information in the spectrum to be unlocked. Enveloping is one such powerful tool, where limits are placed on a good spectrum and if any portion of the spectral region grows beyond the envelope, an alarm is reported - pinpointing the defect developing in the machine.
