Gear Box Failure on Cooling Tower Induction Motor Fan
The large motors in this power plant are attached to a gear box, which is attached to a cooling fan inside the cooling tower. All components are enclosed inside a shroud, making a visual inspection difficult and costly. A knocking noise, possibly coming from inside the shroud, was detected. But was it the motor or the gear box? Watch the video to learn how the problem was analyzed without disassembling the shroud.

Why MEMS Accelerometers Are Becoming the Designer’s Best Choice for CbM Applications
A small number of semiconductor manufacturers have overcome the noise, bandwidth and g-Range shortcomings commonly associated with MEMS sensors used in Condition-based Monitoring (CbM) by producing several medium and high-performance MEMS vibration sensors with the latter being comparable to piezo accelerometers.
