In the field of rotating machines, it is necessary to monitor & online diagnosis for the analysis of vibrations of the machine. This paper focused on vibration signals which are taken from developed prototype of a Rubber Roll Sheller Machine and FFT analysis is performed on the acquired signals under no load & load Conditions. This newly developed data acquisition system is capable of acquiring vibration data from various rotating machines under different load conditions which can further be utilized efficiently for the condition monitoring of machines under various test conditions. This approach carries simplicity & flexibility from other techniques and also it is easy to operate, quickly installed, computer friendly approach and it is cost effective.
