Technical Document: Precision Diagnosis of Bearings Using 3D Envelope FFT
Explanation materials for "Precision diagnosis of bearings using FFT of low-frequency band vibration acceleration 3-axis vector composite waveforms utilizing the vibration sensor conanair."
The "Wi-Fi Vibration Sensor Conan Air," developed by Chūzan Water Heat Industry, is a Wi-Fi vibration sensor that can be introduced for around 30,000 yen (excluding tax) and is used for simple abnormal detection of machinery and equipment. - Conan Air Official Website https://conanair.com/japan/ By utilizing Conan Air, we successfully performed frequency analysis using the three-axis composite waveform of vibrations, leading to abnormal diagnosis of bearings and bearing diagnosis. This data analysis technology has made it possible to conduct precise diagnosis of bearings, which previously required high-performance and expensive sensors, using "Conan Air." ★ This document provides a technical explanation of "Precision Diagnosis of Bearings Using FFT of Low-Frequency Vibration Acceleration Three-Axis Vector Composite Waveform." It is available for free, so please check it out from [PDF Download].
basic information
【Key Points of This Technology】 ◎ Achieves precision diagnosis of bearings equivalent to high-performance vibration sensors ◎ Sensor installation direction is irrelevant due to 3D envelope FFT ◎ Effectiveness is expected to be confirmed even for "low-speed bearing diagnosis," which is considered difficult ◎ All models will be supported through free software updates
