Technical Document: Precision Diagnosis of Bearings Using 3D Envelope FFT
Vibration Monitoring Device Conan Air: IoT-Compatible 3D Digital Twin / Improving Equipment Maintenance and Labor Reduction through DX Promotion and System Integration / Preventive Maintenance
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].

Company information
Our company, headquartered in Suzuka City, Mie Prefecture, has a history of over 50 years and contributes to the maintenance and upkeep of factory equipment through two business divisions: the digital twin construction division utilizing our self-developed Wi-Fi vibration meter, and the piping and mechanical equipment construction division for factory equipment support. - Digital Twin Construction Division By combining INTEGNANCE VR from Brown Reverse Co., Ltd., which represents factories in a virtual space and realizes the digital transformation (DX) and digitization of maintenance operations, with Conan Air, we can create 3D data of all equipment and piping within the plant. By incorporating Wi-Fi vibration sensors, we can establish a labor-saving system for maintenance management using digital twins and generative AI. All safety management can be conducted on a computer monitor, enabling predictive maintenance to prevent equipment troubles before they occur, thus achieving workforce reduction and decreased man-hours. - Piping and Mechanical Equipment Construction Division Based on our extensive experience and know-how, we excel in providing prompt and careful construction, detailed responses across various fields, and high cost performance. We primarily focus on mechanical equipment construction centered around piping, while also integrating and managing operations related to electrical, instrumentation, control systems, painting, insulation, construction, and civil engineering across multiple fields.
