Desenvolvimento de um data logger de vibração de baixo custo para uso em manutençao preditiva

Abstract

This work develops a low-cost vibration analysis equipment prototype, using an accelerometer Micro-Electro-Mechanical Systems technology (MEMS) for data collection, aiming to predictive maintenance of pumping systems equipment. The implementation consists of the assembly and design of a prototype that uses a MEMS accelerometer to collect vibration data on rotating machines, which enables the detection of failures in the operation of equipment. The vibration data are collected by a microcontroller and then saved on an SD card, where they are stored for later analysis. The estimated data logger price was R$ 87.32, well below similar equipment commercially available. The results presented from this work are the equipment itself and the data collected by it. The results of experimental tests were satisfactory, since the data logger worked in an expected way, reaching the objectives of this work.
