Instrumentation

In high-risk industries such as petrochemicals, explosion-proof control rooms are critical barriers to ensure the safety of personnel and equipment. However, a seemingly basic question—how should instrumentation cables be introduced into these rooms—has sparked considerable debate in design practices. What do the regulations say about this? Beyond the controversial approaches, are there more standard and […]

In the industrial control sector, if PLCs are considered the limbs and DCS (Distributed Control Systems) the skeleton, then FCS (Fieldbus Control System) can be seen as the nervous system that connects it all. You may have rarely heard of FCS, but it quietly revolutionizes modern factories. Imagine a scenario where all intelligent devices in

Automatic dimming of the screen on servo level gauges is usually related to energy-saving settings, ambient light sensors, power supply issues, or hardware faults. Below are the specific causes and troubleshooting directions: Common Causes and Analysis: Energy-saving/Auto-sleep SettingsMost servo level gauges have an automatic energy-saving feature: if the screen is idle for a period (e.g.,

When wiring in non-explosive hazardous areas, the safety spacing between different types of cables varies depending on factors such as the type of cable and the method of installation. Below are some common safety spacing requirements: 1. Parallel Wiring of Power and Low Voltage Cables According to GB50311-2016 “Comprehensive Cabling System Engineering Design Specifications”, the

1. A Revolution in Industrial Communication In the realm of industrial automation, communication protocols are as essential as language itself. In 1979, Modicon (now Schneider Electric) introduced the Modbus protocol, designed to solve the problem of “incompatibility” between devices. At that time, each manufacturer used proprietary protocols, making it difficult for devices from different companies

In industries such as chemical production, paint manufacturing, and energy transportation, concepts like flash point, fire point, and auto-ignition temperature (AIT) are not abstract physical phenomena but critical temperature thresholds that define safety and risk levels. Understanding their differences and relationships is the foundation of fire and explosion safety design, storage, and transportation management. 1.

In fire safety design reviews for construction projects, even though the fuel storage room in a diesel generator room may not be large, it often faces scrutiny. Experienced designers often encounter a situation where an expert casually reviews the design and says, “Hey, no flammable gas detectors here?” followed by, “This poses a major safety

In industries such as chemical engineering, environmental protection, pharmaceuticals, municipal projects, and energy, pump selection is one of the most critical steps during the design phase. Proper pump selection directly impacts the operational safety, energy efficiency, and overall cost-effectiveness of the system. Through consultations with experienced professionals in design institutes, we have summarized the key

OverviewWhen wiring in non-explosion-proof zones, it’s crucial to prevent intersections with other areas such as explosion-proof zones, high-voltage zones, low-voltage signal zones, and water/gas pipeline areas. The primary goal is to avoid interference, mitigate safety risks like leakage or short circuits, and ensure system stability. This can be achieved through systematic design focused on physical

1. Overview of Temperature and Pressure Compensation Temperature and pressure compensation is a technique used to automatically adjust the measurement results of instruments to standard conditions, specifically 25°C and 1 standard atmosphere pressure. This is done by measuring the actual temperature and pressure on-site and using a compensation formula to convert the readings to standard
