Infrared thermography—using thermal imagers to detect radiation (heat) from objects—is a powerful tool for condition monitoring and predictive maintenance. By converting heat into temperature data and displaying it as a visual thermogram, practitioners can see hidden problems that are invisible to the naked eye, allowing early detection of equipment faults before they lead to costly failures.This book is a comprehensive, practical guide featuring over 100 real-world thermal images from diverse industrial settings, including fertilizer plants, chemical facilities, and crystal-glass production. Readers will learn to identify common failures across a wide range of equipment, including: Pumps and compressors Transformers and motors Engines and other critical mechanical assets Beyond industrial applications, the book also explores infrared imaging in construction, medical, and civil engineering, demonstrating the versatility of this technology across multiple fields.Whether you are a maintenance engineer, reliability professional, or condition monitoring specialist, this guide equips you with practical techniques, visual examples, and actionable insights to integrate infrared analysis into your preventive and predictive maintenance programs, helping you minimize downtime, reduce costs, and improve equipment reliability.
