🔹 Introduction In many automation projects, the same task—such as laying 100 meters of two-core instrumentation control cable—may yield different outcomes for different contractors. Some profit handsomely, while others suffer losses. Why does this happen? The core reason lies not in technical skill or management loopholes, but in the differences in engineering cost estimation methods.
Have you ever underestimated the seemingly simple yet profoundly significant instrument, the pressure gauge? In the chemical industry, selecting and installing pressure gauges is an intricate science. A suitable pressure gauge not only ensures accurate measurements but also impacts the safety and efficiency of the entire production process. Today, we’ll discuss some details you can’t

Introduction In Safety Instrumented Systems (SIS), it is strongly discouraged to route Digital Input (DI) and Digital Output (DO) signals through the same multi-core cable. While this may seem convenient or cost-saving, it is considered poor engineering practice and is typically unacceptable in systems that require high integrity and reliability. Below is a detailed technical
