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

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 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
