Introduction In hazardous environments, explosion-proof equipment plays a critical role in ensuring safety. However, safety inspections often reveal a persistent issue: faulty or missing instrument nameplates. Statistics show that nameplate-related problems account for nearly 30% of all explosion-proof equipment issues found during inspections. These problems can be challenging to rectify, yet they are crucial for […]

In recent years, advancements in technology and the increasing demands of safety management have led to continuous upgrades in safety inspection standards. As we approach 2025, the focus of safety inspections will remain on key areas such as explosion prevention, lightning protection, grounding, and Safety Instrumented Systems (SIS). However, the direction and specifics of these

In modern mechanical engineering and equipment design, a clamp plays a critical role as a connection and fixing element in various industrial processes. It is widely used in equipment, pipelines, fittings, and mechanical systems. Whether in small household appliances or large industrial machinery, clamps serve an irreplaceable purpose. This article will explore the structure, types,

During the installation, operation, and maintenance of instrumentation equipment, electrical shock prevention is a common and critical safety measure. Electrical shock protection refers to preventive measures taken to safeguard human life from electrical accidents that may result from improper operation, equipment failure, or excessive voltage. The consequences of electrical shocks are often severe, ranging from

Introduction Non-full pipe flow measurement is a notorious challenge in various industries such as municipal wastewater management, agricultural irrigation, and industrial processes. The complexity increases significantly when dealing with large-diameter pipelines (DN800 and above), slight positive pressures, and slurry conditions. Selecting an unsuitable measurement method can lead to inaccurate readings, high maintenance costs, and operational

In thermal control systems, proper wiring plays a crucial role in ensuring the stability of signal transmission and the safe operation of equipment. However, due to improper design, poor maintenance, or incorrect installation practices, common wiring issues often arise. These problems can lead to signal interference, equipment malfunctions, and even safety hazards. Below are some

Signal isolators play a crucial role in modern electrical and electronic systems by ensuring the safe and accurate transmission of signals across different electrical environments. They are widely used in industries such as automation, healthcare, telecommunications, and power systems. This article provides an in-depth analysis of the functions, benefits, and applications of signal isolators. What

In industrial settings, especially in hazardous environments where there’s a risk of explosion or fire, maintaining electrical safety is of utmost importance. Zener barriers and isolated barriers are both crucial devices used to protect intrinsically safe circuits (i.e., circuits designed to prevent ignition of hazardous gases or dust). Although both safety barriers aim to prevent

1. Scope This standard specifies the classification, methods, system structure, grounding resistance, and design principles of instrument system grounding. It aims to ensure safe and reliable grounding for instrumentation and control systems to prevent electrical hazards and interference. 2. Grounding Classification and Methods 2.1 Protective Grounding Protective grounding is implemented to prevent electric shock and

Introduction Continuous Emission Monitoring Systems (CEMS) are essential tools for tracking and regulating air pollution emissions from industrial sources. These systems provide real-time, continuous data on the concentration of various pollutants in exhaust gases, ensuring compliance with environmental regulations. CEMS is widely used in industries such as power generation, steel manufacturing, cement production, and glassmaking
