Addressing High Temperature, High Humidity, Heavy Rainfall, and Lightning Conditions 1. Environmental Protection: Coping with Summer Hazards 1.1 Heat Dissipation and Temperature Control Inspect cooling components such as fans and ventilation grilles in control cabinets; clean dust, plant debris, or insects that may block airflow. Avoid direct sunlight exposure on instruments; install sunshades or reflective […]

In the field of flow measurement and process instrumentation, three terms frequently appear: Reynolds number, laminar flow, and turbulent flow. These are not just academic concepts—they are crucial for instrument selection, pipeline design, and process optimization. 🔢 What Is Reynolds Number (Re)? The Reynolds number (Re) is a dimensionless value used to predict the flow

Automation instrumentation plays a critical role in industrial control systems as the “peripheral nerves” of production. When such equipment reaches the end of its life due to aging, damage, or obsolescence, a standardized decommissioning and disposal process is essential to ensure compliance, safety, and efficient asset turnover. This document outlines the key steps, standards, and

1. Introduction: Why Drum Level Matters In power plants, cogeneration systems, and any facility involving boilers, the term “drum level” is critical. While it may seem like a basic parameter, drum level is actually a complex topic encompassing measurement principles, control strategies, and failure management. Improper drum level control can lead to reduced boiler efficiency

NAMUR NE 43 is a widely adopted signal standard in the field of industrial automation, primarily used for transmitting fault conditions and diagnostic information in process control instruments. This standard defines specific ranges within analog signals (typically 4 to 20 mA current signals) that indicate normal operating states and those that signify device faults or

1. Introduction The review of instrumentation construction drawings is a critical step to ensure project safety, efficiency, and cost-effectiveness. A thorough and systematic review helps identify potential issues in advance, avoiding errors and rework during construction. This document outlines the key aspects and best practices for reviewing instrumentation drawings. 2. Pre-Review Preparation As the saying

In the world of industrial automation and electrical safety, terms like protective earthing (PE) and enclosure grounding are often used interchangeably. However, while they may physically share the same grounding point, their purposes, design principles, and regulatory implications are fundamentally different. Understanding this distinction is crucial for engineers, electricians, and system integrators alike. ✅ What

Chemical instrumentation plays a vital role in ensuring the safe and stable operation of chemical production processes. Proper selection must comprehensively consider process conditions, media characteristics, environmental requirements, measurement accuracy, and more. This guide presents the core logic and key steps for instrument selection in chemical industries. 1. Define Process Requirements: Start with the Measurement

Natural weather phenomena such as wind, rain, lightning, and stray electricity can significantly impact field instrumentation. These effects span mechanical, electrical, and environmental domains, potentially resulting in measurement inaccuracy, device failure, or even catastrophic damage. This document outlines the risks and provides comprehensive protective strategies. 1. Impact of Wind 1.1 Mechanical Damage Strong winds may

1. Introduction In petrochemical plants, rotating machinery such as compressors and large process pumps play a vital role in stable and continuous production. These machines often operate under high temperature, high pressure, and hazardous conditions, demanding rigorous control and monitoring. Shaft instrumentation systems provide critical data on key parameters such as shaft vibration, axial displacement,
