Industrial Sensors: Applications, Selection, and Troubleshooting for Electricians and Technicians: A Practical Field Guide to Understanding and

Industrial sensors are everywhere—but when they fail, everything stops. This book is a practical, real-world guide to understanding, selecting, and troubleshooting industrial sensors in the field. Whether you're dealing with a machine that won’t start, a process that won’t stabilize, or a signal that just doesn’t make sense, the problem often comes down to one thing: the sensor. Written from over 36 years of hands-on electrical experience, this guide cuts through the theory and focuses on what actually matters when you’re standing in front of a machine trying to figure out what’s wrong. Inside this book, you’ll learn: How different types of industrial sensors actually work in real-world applications - How to properly select the right sensor for the job - Common failure points and how to spot them quickly - Step-by-step troubleshooting methods used in the field - How to test sensors using meters and real diagnostic techniques - Understanding signals like 4–20 mA, voltage outputs, and switching devices - How sensors interact with PLCs, control circuits, and automation systems This is not a theory-heavy engineering book. It’s a field guide built for electricians, maintenance technicians, and anyone working around industrial equipment who needs clear answers and reliable troubleshooting methods. If you’ve ever chased a problem through a control system only to find out it was a sensor all along, this book will save you time, frustration, and unnecessary part replacements. Whether you're experienced or still learning, this book will sharpen your troubleshooting skills and help you diagnose sensor-related problems with confidence. If you work on industrial equipment, you need to understand sensors. This book shows you how.
