A modern solution to an age old problem The condition based monitoring (CBM) market is awash with new technologies and new ways to monitor problems that are as old as the industrial revolution. I am sure that the French inventors of the first modern automotive transmission had issues with shaft alignment, poor lubrication, excessive vibration and surface pitting. Panhard and Levassor, working over 125 years ago, would have loved to get their hands on some of the technology that today we take for granted. But faced with so many choices, what sets different technologies apart from one another and...

Other variables Troubles at low speed In our analogy we said that the faster your car is going the bigger the jolt. Conversely, slowly driving over a pothole will cause little jolt at all. In the equation if you travel over the same pothole at ever increasing speeds the jolt you will feel becomes stronger the faster you travel. F = MA What this means for a vibration sensor is that there is a whole load of vibration to pick up at high speed, but it gets harder to measure reliably at low speeds. If we can’t determine a reliable ‘normal’ how can we compare and be confident when an ‘abnormal’ condition...

WearDetect Summary For higher speed applications the industry standard vibration monitoring system is often sufficient, especially for electric motors. However, for operators of low speed drives who have gearboxes absolutely critical to their processes (and bottom-line profits) wear debris monitoring just makes sense (excuse the pun).
