Ultrasonic detector for predictive maintenance

Abstract

In the industry it is very common for failures to occur in machinery and equipment such as poorly lubricated elements; friction between mechanical elements; gas or vacuum leaks in pressurized systems; and electric arcs in motors, transformers and electrical installations. Each of these faults emits ultrasound and can be detected early using an ultrasonic detector. The objective of this work is to present a proposal for the development of a system capable of opportunely detecting the ultrasound emitted by faults, which is very useful for predictive maintenance. The methodology consists of the development of a system that detects the ultrasound decibels emitted by the fault using an ultrasonic sensor of the last generation, and the necessary interfaces. Ultrasound decibels will increase exponentially in the presence of these flaws, allowing their detection. This document offers an alternative for the development of an ultrasonic system useful in predictive maintenance, which is within the reach of any company.
