Instrument failures can be complex and difficult to diagnose immediately. It’s important to stay calm and analyze the situation step by step. The faults can generally be divided into three sections: on-site detection, intermediate transmission, and terminal display. Seasonal factors, such as preventing high temperatures in summer and freezing in winter, should also be considered. […]

As an instrument technician, it’s essential to learn how to proactively reflect on your work, summarize your experiences, and improve your maintenance skills. This process is key to transforming repetitive tasks into expert-level capabilities. Below is a comprehensive framework that moves from “reflection” to “improvement,” which you can apply based on your own experiences. Part

1. Do You Really Understand Explosion-Proof Nameplates? In chemical plants, it is common to see explosion-proof motors or vibrating level switches with nameplates marked with: Ex ia IIC T4 ~ T6 Ga While many engineers recognize this as the explosion-proof classification, the meaning of “T4 ~ T6” is often misunderstood. This marking refers to the

In the field of instrumentation, understanding the differences between analog and digital instruments is crucial for making informed decisions. This article explains why digital instruments are more stable and less susceptible to environmental interference compared to their analog counterparts. Analog vs. Digital Signals In analog instruments, signals are continuous, meaning they can fluctuate infinitely within

In modern industrial automation, explosion protection is one of the most critical design requirements. Whether it’s in chemical plants, oil and gas platforms, pharmaceutical factories, or coal mining systems, any area with flammable gases or dust requires strict control over the propagation of electrical energy. Among many explosion protection measures, one small device is often

The responsibilities of a Fine Chemical Instrumentation Engineer encompass the design, installation, maintenance, management, and collaboration of instrumentation systems in chemical processes. The key duties are as follows: Instrumentation and Automation System Design and Selection Participate in the design of instrumentation and automation control systems, such as PLC, DCS, and SCADA, based on production process

General Safety Protocols Strictly adhere to all safety regulations and operating procedures. Properly wear and use personal protective equipment (PPE) such as helmets, safety shoes, and protective glasses. Conduct a comprehensive risk assessment and hazard identification in the work environment. Ensure that all equipment and tools are in good condition, and perform regular maintenance checks.
