In environments where explosive materials are present, the grounding of electrical equipment is a critical safety measure. These environments, classified as hazardous locations, often contain flammable gases, vapors, or dust, which, when exposed to electrical sparks or faults, can cause explosions. Proper grounding of electrical equipment is essential to prevent the accumulation of static electricity, […]

The control room in a chemical plant serves as the central hub for monitoring and controlling production processes. Proper management of the control room ensures safe, efficient, and reliable operations. This article outlines a detailed framework for effective control room management, covering personnel, operations, environment, and safety protocols. 1. General Provisions 1.1 The control room

RS-485 is a robust and widely used communication standard, especially in industrial automation, where long-distance data transmission and multiple devices sharing a bus are common. However, despite its inherent noise immunity, improper wiring and external factors can lead to communication interference. In this article, we’ll delve into ways to manage interference in RS-485 systems and

Interlock systems are critical components in many industries, designed to ensure safety by preventing unintended or dangerous operations. However, there are situations where interlock systems may need to be temporarily bypassed or removed, such as during maintenance, testing, or troubleshooting. While this is sometimes necessary, the duration for which an interlock system can be safely

1. Introduction Remote control refers to the ability to monitor and manage the behavior and outcomes of system components located in distant or distributed areas. Programmable Logic Controllers (PLCs), known for their versatile communication interfaces and robust networking capabilities, are well-suited for remote control applications. With continuous advancements in PLC networking modules and architectures, implementing

Selecting and installing an isolated safety barrier (also known as an intrinsically safe barrier) is crucial in hazardous environments to ensure both personnel safety and reliable system operation. These devices are widely used in industries such as oil and gas, petrochemicals, and other sectors where flammable gases, vapors, or dusts are present. To achieve optimal

In the realm of automation, choosing the right communication protocol is crucial for ensuring system compatibility, reliability, and cost efficiency. While BACnet is widely used in building automation systems, Modbus remains the dominant protocol in industrial automation. This article explores both protocols, compares their features, and explains why Modbus is often the preferred solution in

How Radar and Ultrasonic Level Sensors Improve Ship Stability, Compliance, and Fuel Efficiency 1. Importance of Draft Measurement Draft—the vertical distance from the waterline to the lowest point of a vessel’s hull—is one of the most critical parameters in maritime operations. Accurate draft measurement plays a vital role in ensuring safe navigation, reducing the risk

The Safety Instrumented System (SIS) plays a critical role in industrial safety by implementing Safety Instrumented Functions (SIF) to prevent or mitigate hazardous events. Effective management, routine maintenance, and proper fault handling are essential to ensure SIS functionality and system integrity. This article outlines detailed best practices and requirements across these three aspects. 1. Management

Introduction In the realm of industrial automation and smart applications, the RS-485 communication protocol stands out for its long transmission range, multi-point connection support, and cost-effectiveness. However, in complex industrial environments, RS-485 communication can face challenges such as electromagnetic interference (EMI), grounding issues, and ground loops, leading to unstable communication or even complete disruption.
