A DEVELOPMENT OF WIRELESS NOISE TESTING SYSTEM ON CENTRIFUGAL PUMP
Noise monitoring is a predictive maintenance technique that can be used to determine
machine condition. This monitoring can be done in off line and on line system. On line
noise monitoring is conducted by long distance and requires a long cable network.
Development and implementation of wireless noise monitoring and installation can be
overcome the problem. Wireless noise monitoring equipment for machinery condition
monitoring is still very poor information, therefore it is necessary to develop wireless
noise monitoring. The result of wireless noise testing data on the machine is justified by
the analysis of noise testing data with cable system. The research object is a created
wireless noise measurement applied to a centrifugal pump that equipped by a data
acquisition system that operated at constant load and rotation. MathlabTM analysis is
used to justify the noise amplitude, time domain, and frequency domain of wireless and
cabled measurements. The final test results indicate that the noise and wireless spectrum
signals are match with the noise spectrum and signals using cable. The high noise
amplitude occur at 30Hz, 60 Hz dan 120 Hz and 180 Hz.
