Introduction In industrial automation and process control, various types of switches are used to detect and control different parameters. Among them, limit switches and level switches play crucial roles but serve distinct purposes. While both involve switching mechanisms, their applications, working principles, and functions differ significantly. This article will explain the differences between a limit […]

In fluid mechanics, the behavior of fluids as they flow through various systems is of immense importance in both theoretical studies and practical applications. The nature of fluid flow can be classified primarily into two types: laminar flow and turbulent flow. These flow types are influenced by the Reynolds number, a key dimensionless parameter that

Instrument tagging, or instrument numbering, is a system of unique codes used to identify and differentiate instruments in industrial processes. A well-organized and standardized tagging system not only enhances the efficiency of operations and maintenance teams but also minimizes the risk of operational errors and ensures safe, stable production. This article outlines key rules and

1. Introduction In recent years, magnetic float level gauges have been widely used in high-pressure separators for solvent oil hydrotreating units. However, issues related to the magnetic float’s deformation and failure have been observed, leading to inaccurate liquid level readings. One such instance occurred in 2012 when the magnetic float in the high-pressure separator V101

1. Importance of “Four Understandings and Three Skills” In chemical equipment management, it is crucial for operational and maintenance personnel to possess the “Four Understandings and Three Skills”: Four Understandings: Understanding the principles, structure, usage, and performance of the equipment. Three Skills: Being proficient in operation, maintenance, and troubleshooting of the equipment. A real-world case

Instrument calibration is a critical process, especially for B2B clients, with manufacturing factories being the primary audience. But why is calibration so important for factories, and which ones need it? This article explores the necessity of instrument calibration in industrial settings and outlines the key factors to consider. Why Do Factories Need Instrument Calibration? Factories

Introduction In modern industrial automation, managing multiple electric motors efficiently and safely is a significant challenge. A Motor Control Center (MCC) is a crucial solution designed to centralize and streamline motor management. Widely used in industries such as oil & gas, metallurgy, mining, water treatment, and power generation, MCCs play an essential role in motor

A Manufacturing Execution System (MES) is a crucial production management system designed for manufacturing enterprises. It connects the enterprise’s planning layer (ERP) with the on-site control layer (PLC, SCADA, etc.), enabling real-time monitoring of production processes, data collection, quality management, and process execution. The main goal is to improve production efficiency, product quality, and responsiveness.

In chemical production, startups and shutdowns are routine but critical operations. Short-term shutdowns generally have minimal impact on instruments, with limited adjustments needed by instrumentation personnel. However, this document focuses on large-scale shutdowns and startups, such as those due to major overhauls, extensive stoppages, or events requiring prolonged halts and subsequent restarts of operations. Note

Introduction Japanese Industrial Standards (JIS) define various thread types for different industrial applications. These threads are widely used in mechanical components, piping systems, and precision instruments. This article provides an overview of the most common JIS thread types, their characteristics, applications, and examples. 1. JIS Parallel Pipe Thread (JIS B 0202) Designation: PF (Equivalent to
