Abstract: The present article takes as an aim to present a compilation of technical information, referent to acquisition, conditioning and signal analysis of vibration. In the tests of vibrations is necessary to obtain the maximum possible benefit when there are applied the vibration study techniques to a wide range of practical problems of engineering. The maximum benefits are obtained when the instrumentation and the analysis techniques used are the appropriate ones and consistent ones with the aim of the test. The most sophisticated in instrumentation and the best methods of analysis can be easily affected by a deficient assembly, an inaccurate sampling, a bad selection of the instrumentation, etc. Therefore the present work shows the fundamental principles and the general characteristics that surround a test of vibrations.

Resumen: El presente artículo tiene por objetivo presentar una recopilación de información técnica referente a la adquisición, acondicionamiento y análisis de señales de vibración. En los ensayos o pruebas de vibraciones es necesario obtener el máximo beneficio posible cuando se aplican técnicas de estudio de vibraciones a un amplio rango de problemas prácticos de ingeniería. Los máximos beneficios se obtienen cuando la instrumentación y las técnicas de análisis utilizadas son las apropiadas y consistentes con
los objetivos de la prueba. Lo mas sofisticado en instrumentación y los mejores métodos de análisis se pueden fácilmente verse afectados por un pobre montaje, un inexacto muestreo, una mala selección de la instrumentación, etc. Por lo tanto el presente trabajo muestra los principios fundamentales y las características generales que envuelven un ensayo o prueba de vibraciones.

Keywords: Vibration, Sensor, Data acquisition, Noise, Filters, Signal vibration.
