Electrical leakage is a common yet dangerous issue in both home appliances and industrial equipment. It can cause electric shocks, equipment failure, or even fires. In this guide, you’ll learn how to measure electrical leakage using a digital multimeter, the types of leakage to watch for, and which tools are best suited for the job.

Introduction In industrial environments where flammable gases or vapors are present, understanding explosion limits—also known as LEL (Lower Explosion Limit) and UEL (Upper Explosion Limit)—is not just a technical concern, it’s a life-saving necessity. One spark, and an entire facility can be at risk. This article will help you understand how to manage explosion risks,

In electrical and instrumentation control systems, dry contact and wet contact are two commonly used signal types. These terms describe the way electrical signals are transmitted between devices such as relays, switches, and programmable logic controllers (PLCs). Understanding the differences between these two contact types is essential for designing and troubleshooting control circuits. 1. What

The selection of calibration gas in the calibration process of flammable gas detectors is a critical factor that directly affects the accuracy of calibration results and the long-term performance of the equipment. This article analyzes the selection of calibration gases, the issue of conversion factors, and related standards. Special attention is given to the feasibility
