Instrumentation

Industrial Control Systems (ICS) are the “nervous system” of key sectors such as manufacturing and energy supply, and their network security directly determines the stability of production and even the safety of physical environments. However, many technicians encounter confusion when dealing with ICS security. Today, we will clear up some common but often overlooked points. […]

The UQK-6100 series float level switch operates by utilizing the buoyancy principle of Archimedes. As the float moves with the liquid level, the primary magnet inside the pressure tube moves vertically. The mechanical switch, which is adjustable, is located outside the pressure tube in the housing. The movement of the primary magnet triggers a secondary

1. Why is Air Tightness Important? Whether it’s a new energy vehicle battery pack, a high-pressure gas pipeline, or a semiconductor vacuum etching machine, their operational stability hinges on an invisible parameter—air tightness. Air tightness testing is not simply about detecting air leaks; it’s a systematic safety validation and process control method. It determines whether:

Behind the complex codes and systems, lies the key to a company’s future success or failure. “Transform or die, stagnate and perish.” This has become the harsh reality for 70% of companies today. In this silent war, a new department—the Digital Transformation Department—is quickly rising in many organizations. From traditional manufacturing to internet giants, from

I. Daily Inspection Guidelines Inspections should combine visual, auditory, tactile, and measurement methods to ensure the system is functioning optimally. 1. Visual Inspection Steam Supply and Condensate Drainage: Check if the pressure in the main steam line and steam headers falls within the normal range (typically 0.3~0.8MPa). Observe the condensate drain for proper discharge of

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
