Anyone who works with materials can’t avoid one key term — creep. Have you ever encountered this? A plastic part slowly deforms over time? A PTFE gasket that fit perfectly at installation ends up sagging after a few months? Is this because the material is just too “soft”?Or is there something deeper—perhaps molecular structure—that leads […]

In modern industrial automation systems, Distributed Control Systems (DCS) play a critical role in monitoring and controlling various process parameters. However, a common question arises during system configuration: Should every parameter in a DCS have an alarm? The short answer is: not necessarily. Over-alarming can lead to alarm fatigue, unnecessary operator stress, and ultimately reduce

Understanding the Root Causes and How to Prevent Them 1. Background: A Common Yet Costly Problem Many industrial users—especially in chemical plants—have reported frequent failures with corrosion-resistant probes from various brands. Despite switching suppliers, the coating on the sensor heads often peels off within a few months, leading to corrosion and sensor malfunction. Instrumentation in

In modern industrial production, large storage tanks play a crucial role. They are used not only to store various liquids and bulk solid materials but are also widely applied in industries such as petrochemicals, food processing, and water treatment. Accurate measurement of the material level in these tanks is one of the key factors to

Introduction You may have noticed that when a constant load is placed on a weighing system, the reading slowly drifts over time—even though nothing changes physically. This is not a failure or signal instability.It’s called load cell creep—a natural behavior of strain-based transducers. In this article, we explain what creep is, what causes it, how

In recent years, with the continuous advancement of infrastructure construction in China, asphalt concrete has become a crucial material in road construction. During the production of asphalt concrete, monitoring and measuring the material levels in silos is key to ensuring smooth production. However, traditional methods of level measurement often have limitations, such as low accuracy

Vortex flow meters are trusted for steam flow measurement due to their robustness, high-temperature tolerance, and low maintenance. But like any instrument, they can face problems in real-world applications. This guide walks you through typical problems, their causes, and practical solutions, especially in steam service. 🛠️ Issue 1: No Flow Signal or Constant Zero Output

In modern industrial systems, Distributed Control Systems (DCS) are widely used to monitor and control motor operation in real-time. One common issue that often arises during operation is a mismatch between the DCS feedback current and the actual motor current. This discrepancy, if not addressed properly, may result in control errors, false alarms, or even
What to Do When DCS Motor Feedback Current Does Not Match the Actual Current? Read More »
Cable laying standards are essential to ensure the safety, stability, and longevity of cable systems in industrial and infrastructure projects. This guide outlines key procedures and technical considerations, covering pre-installation checks, installation in various environments, cable fixing and spacing, joint and terminal production, and safety precautions. 1. Pre-Installation Preparation 1.1 Cable Inspection Visual Check: Ensure
