In today’s industrial environments, system uptime and reliability are crucial. Whether you’re running a data center, a chemical processing plant, or an automated manufacturing line, even a brief power failure can lead to costly downtime, product losses, or safety hazards. That’s where power redundancy modules come into play. This article explains what a power redundancy […]

Routine inspection in industrial environments is more than a formality—it’s a vital part of equipment management and risk prevention. This article provides a comprehensive guide to the purpose, methods, responsibilities, and common pitfalls in inspection work, with practical strategies for ensuring safety and reliability. 1. Purpose of Routine Inspection The core goal of routine inspection

In modern industrial automation and process control systems, ensuring uninterrupted power supply is critical, especially for sensitive instrumentation such as Distributed Control Systems (DCS), Safety Instrumented Systems (SIS), and Programmable Logic Controllers (PLC). To enhance power reliability, dual UPS (Uninterruptible Power Supply) configurations are commonly deployed. However, one key engineering decision is whether to operate

Introduction Circuit breakers are critical components in electrical systems, designed to close, carry, and interrupt electrical currents under normal operating conditions and to disconnect the circuit during abnormal conditions like overloads, short circuits, or undervoltage. These devices are broadly classified into high-voltage and low-voltage circuit breakers. Generally, devices operating above 3kV are considered high-voltage. Circuit

Distributed Control Systems (DCS) are the backbone of modern industrial automation, responsible for real-time control, monitoring, and data acquisition. However, like all complex systems, DCS components can experience a variety of faults that may lead to process interruptions or safety risks. This article summarizes the most frequently encountered failures in DCS systems and provides practical

Introduction: Ensuring Reliable Liquid Level Measurement in Harsh Industrial Environments In high-temperature, high-pressure, and highly corrosive industrial environments, ensuring accurate and stable liquid level measurement is a significant challenge. Tuning fork level switches, known for their high precision and reliability, are widely used in various industries. However, their performance largely depends on their core component—the

In the field of industrial automation, instrumentation devices are essential for accurate measurement, control, and safe operation of modern production systems. Proper grounding of instrumentation equipment is not only a technical requirement but also a safety-critical measure to ensure reliable operation, signal integrity, and protection from electrical hazards. This article provides a comprehensive overview of

In industrial automation and control systems, the quality of compressed air plays a crucial role in ensuring reliable operation. Among various types of compressed air, instrument air refers to the purified, dry air supplied specifically to pneumatic instruments and control systems. This article explains the differences between plant air and instrument air, and provides a

1. Structural Definitions Symmetrical Cable Structure A symmetrical cable is one in which all conductors (e.g., three-phase power lines) are arranged in a geometrically balanced pattern, typically with: Equal spacing between conductors Identical insulation, shielding, and sheathing across all cores Consistent physical and electrical characteristics Example: A 3-core cable with conductors arranged in an equilateral

1. Determination of Pump Selection Parameters 1.1 Physical and Chemical Properties of the Medium The medium’s properties directly affect the pump’s performance, material selection, and structural design. Key considerations include: Corrosiveness, toxicity Presence of solid particles (content and size) Viscosity Tendency to crystallize 1.2 Process Parameters Flow Rate (Q): Minimum, normal, and maximum operational flow
