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

With rapid industrialization and urbanization, wastewater discharge has increasingly become a global concern. Wastewater treatment equipment plays a critical role in addressing these issues by purifying wastewater, preventing environmental contamination, and promoting efficient reuse of water resources. Modern wastewater treatment equipment emphasizes automation and Internet of Things (IoT) technologies to enhance operational efficiency and stability

Introduction The proper arrangement of pressure, temperature, and flow instruments, along with valves, in a pipeline system is crucial for accurate measurement, efficient control, and safe operation. Incorrect placement can lead to measurement errors, inefficient system performance, and potential safety hazards. This article outlines the general guidelines and best practices for installing these instruments to

When performing routine checks on a chemical instrument pressure transmitter, the following steps should be followed to ensure its proper functioning and accuracy: 1. Visual Inspection Inspect the transmitter’s exterior for any visible damage, deformation, or corrosion. Ensure that the housing is intact and free from cracks or other physical issues that might compromise its
