Future of Condition Monitoring

Monday, January 23, 2012

The ultimate goal of condition monitoring is to increase profitability by lowering maintenance costs and minimizing downtime. The goal can be achieved by making required changes to make sure that equipment is more reliable. The machines should be monitored every period of time to detect problems in early stage so that the most cost effective and timely repairs can be planned. Management commitment, proper staff training, and a high level of dedication are required to achieve these goals. Read More

Dynamic Balancing

Friday, January 20, 2012

In a previous topic I had discussed static balancing of rotating component; this form of balancing is acceptable for objects whose aspect ratio--the ratio of its length relative to the diameter--is relatively small. However, rotating parts with a greater aspect ratio should be balanced in more than one plane. Read More

Risk Assessment: Selecting the Best Technology for Vibration Monitoring

Monday, January 16, 2012

It is recommended to perform review of all the plant equipment before selecting the technology to monitor vibration and detect faults. There are issues that should be considered when selecting technology such as: Read More

Spectral Vs. Waveform Data

Friday, January 13, 2012

Spectral data is displayed in the frequency domain while waveform data is in the time domain. Spectral information is obtained by applying a Fourier transform to waveform data; this converts the data to show that amplitude and phase of the vibration at different frequencies. Read More

Vibration Meters

Tuesday, January 10, 2012

Vibration meters are handheld instruments which are connected to and receive a signal from a vibration transducer and have a capability to process data so as to give an indication of vibration parameters. They are sometimes made specifically to meet certain standard, for example, ISO 2631 for Human Vibration or ISO 2372 for Vibration Severity of Rotating Machines. This blog article is focused on more general-purpose vibration meters. Read More
