Instrumentation

In the field of chemical manufacturing, safety is not only a moral responsibility but also a core element of sustainable operation. In China’s chemical safety management framework, the term “Two Key Points and One Major” forms the foundation of process safety control. However, many companies know the concept but struggle with implementation. This article explains what […]

In chemical and process industries, instrumentation often operates under challenging high-temperature conditions — such as medium-pressure steam, thermal oil, or crystallizing process fluids. These environments demand not only reliable measurement and control performance but also effective thermal management. Temperature, pressure, and level instruments must remain accurate, while their electronic components stay within safe limits. This

1. The Debate: IIoT vs. DCS — Rivalry or Reinvention? A recent trending article claimed that the Industrial Internet of Things (IIoT) will “replace DCS and lead the era of Industrial Revolution 5.0.”It reignited a long-standing argument in the automation community — can IIoT truly replace the Distributed Control System (DCS)? Supporters of this view

The monthly report should focus on five key dimensions:Work Achievements – Problem Analysis – Risk & Solution – Capability Improvement – Next Month Plan.All sections should contain measurable data, clear outcomes, and traceable actions. The goal is to present both value creation and problem-solving capabilities. 1. Major Work Achievements This Month (Quantified results + relevance

Introduction In the full lifecycle of process instrumentation, maintenance is not a single-stage activity but a continuous, evolving strategy. Preventive, predictive, and proactive maintenance are not isolated tasks performed at different times—they form a progressive reliability chain that connects time, condition, and root cause. The earlier and deeper these three dimensions are integrated, the longer

In hazardous environments such as petrochemical plants, battery material production, paint shops, and gas processing facilities, bringing ordinary electrical equipment safely into explosive areas is a major challenge.One of the most reliable engineering solutions is Positive Pressure Explosion Protection (Ex p). This article provides a comprehensive explanation of the Ex p principle, classification standards, key

In many industrial accidents, the root cause isn’t the equipment itself — it’s a lack of gas detection knowledge.A worker enters a confined space without checking oxygen concentration and passes out due to hypoxia.A chemical plant’s gas alarm goes off by mistake — because the operator confused “PPM” with “mg/m³”.These are not rare mistakes. They

Electrical cable entry is a critical aspect of explosion-proof equipment design and installation. It plays a pivotal role in maintaining safety in hazardous environments, such as those containing explosive gases, vapors, or dust. However, improper handling or oversight in this area can lead to severe risks. This article provides an in-depth explanation of common hazards

Stress rupture, exacerbated by corrosion and mechanical damage, is a critical issue in the design, maintenance, and operation of precision instruments. This article delves into the mechanics of stress rupture, the role of corrosion in accelerating material failure, and the contribution of mechanical damage to stress concentration. It concludes with practical strategies for prevention and

Introduction Sulfuric acid (H₂SO₄) is one of the most widely used chemicals in industrial processes, ranging from fertilizer production and petroleum refining to chemical synthesis and wastewater treatment. However, its strong corrosiveness poses a critical challenge for material selection and equipment design. The corrosion behavior of stainless steels in sulfuric acid is primarily governed by
