Abstract: The present invention contemplates the distribution and network connection of instrumentation units, wherein each consists of a firmware based on a microcontroller and temperature and vibration sensors. These units, designated as measurement nodes, are installed at various points along the casing of the pieces of equipment that make up a subsea submersible centrifugal pump (SCP), enabling the characterization of temperature profiles and different modes of vibration throughout the body of the drive, opening the possibility of relating the operational condition to the measured data and of performing predictive actions that promote the increase of the useful life of the pieces of equipment. The present invention also contemplates the boarding of a microcontroller unit for processing the sensor signals. In addition to processing vibration components sampled at high frequency, the microcontroller unit will enable the transmission of such signals at low frequency to the platform.
