Introduction When selecting a load cell, one of the most important—yet often misunderstood—factors is accuracy class. Labels like C3, C4, or Class A are commonly found in load cell datasheets, but what do they actually mean? This article explains the purpose of these accuracy classes, how they’re defined, and how to choose the right one […]

A Loss-in-Weight Feeder is a precision gravimetric dosing system designed to deliver consistent and accurate material flow rates. It operates by continuously measuring the weight loss of the material in a hopper over time, adjusting the feed rate to match a predetermined setpoint. This method ensures high accuracy in feeding powders, granules, or liquids, making

In industrial facilities, instrumentation technicians (also known as instrument fitters or instrument mechanics) play a vital role in maintaining measurement and control systems. Their responsibilities often overlap with electrical work, especially in process industries. This raises an important question: Should instrumentation technicians hold certifications for low-voltage electrical work and explosion-proof electrical installations? This article explores

1. System Capacity Specifications a) Redundancy and Reserve Rules I/O Modules Reserve ≥ 10% of each type of I/O points Reserve ≥ 10% of module slots (plug-and-play ready) Controller Processing Capacity ≥ 60% margin under normal conditions ≥ 40% margin under stress conditions Operator/Server Workstations ≥ 60% CPU margin under stress conditions Memory Capacity ≥

As industrial automation systems grow increasingly complex, traditional PID controllers—though reliable and widely used—are no longer sufficient for meeting the rising demands of precision, safety, and efficiency. This has led many process industries, especially petrochemical plants, to explore advanced control strategies like Model Predictive Control (MPC). But does MPC always outperform PID? What are the
