Used to detect and monitor vibration in rotating machinery

accelerometer it has a sensor that can detect the vibration of a rotating machine

Hi..

The device used to detect and monitor vibration in rotating machinery is Accelerometer..So answer is 'C'

with regards

C. Accelerometer

Vibration monitoring is reported as an interesting technique for the rotating machinery condition diagnosis. Wavelet Transform (WT) and FFT of vibration signals to detect and diagnose of unbalance faults in rotating machinery. The fault condition and location of faults are successfully detected by WT-FFT for non-stationary vibration measurements obtained from accelerometer sensors.

Used accelerometer to detect vibration.

The correct answer is: C. Accelerometer

I'm not aware about mechanical maintenance but I gained good information from the Q & Answers, Thanks

I will choose choice (A) Transducer.

I would like to add 

A. Transducer + B. Brobe used to measure the vibration also in Bently Nevada system for rotating machine. Vibration such axial vibration for the shaft

C. Accelerometer as seismic sensor.

I cannot find what a Brobe is, but a transducer can measure energy and convert it, into energy, so measurable. So I think A

The fault condition and location of faults are success fully detected by WT-FFT for non-stationary vibration measurements obtained from accelerometer sensors
