Understanding Risk Classification Control and Hazard Identification The Dual Prevention Mechanism is a safety management strategy consisting of two essential components: Risk Classification Control Hazard Identification and Rectification These two elements work hand-in-hand to proactively prevent accidents in the workplace by ensuring both preventive control of risks and timely correction of hazards. 1. What Is […]

In industrial and laboratory temperature measurements, RTDs (Resistance Temperature Detectors) are widely used due to their accuracy and stability. However, to measure temperature precisely, it’s essential to consider not just the RTD sensor itself, but also the effect of the lead wires connecting the RTD to the measuring instrument. Lead wires have resistance of their

Maintaining stable and reliable instrument signals is crucial in industrial settings. Signal instability and occasional disconnections can disrupt operations, affect system performance, and compromise safety. This article explores the benefits and limitations of using safety barriers as a potential solution to address these issues. The Functionality of Safety Barriers Safety barriers play a vital role

Electrical measurement and diagnostics rely heavily on specialized instruments designed for specific testing scenarios. Among the most commonly used devices are the multimeter and the megohmmeter (often referred to as an insulation resistance tester). While both are essential tools for electrical technicians and engineers, they serve very different purposes and operate on distinct principles. This

When designing or maintaining industrial systems, one common question arises: Can a pressure gauge and a thermometer be installed in the same location? The answer largely depends on the specific system requirements, measurement accuracy, and safety considerations. This article explores the factors influencing the placement of pressure gauges and thermometers, potential challenges, and recommended best

1. Introduction Transistors and bipolar junction transistors (BJTs) are fundamental components in electronics, playing crucial roles in signal amplification, switching control, and power regulation. Although the terms “transistor” and “BJT” are sometimes used interchangeably in casual discussions, they have distinct meanings in technical and historical contexts. This article explores the differences between transistors and BJTs,

To effectively monitor and control an industrial process, it is essential to measure parameters such as temperature, pressure, flow, and liquid level in real time. The instruments used to perform these measurements are referred to as measurement instruments or sensing devices, and they include: Indicating Instruments: Provide real-time readings. Transmitters: Convert physical parameters into standardized

1. Purpose This document is established to strengthen the management of instrument control systems, including DCS (Distributed Control System), SIS (Safety Instrumented System), and PLC (Programmable Logic Controller), ensuring their safe and stable operation. It also aims to improve the environmental quality of the control cabinet room, facilitate maintenance, and prevent accidents. 2. Scope This

A comprehensive guide for instrumentation professionals and engineers Introduction Instrumentation terminology is foundational in process automation, instrumentation engineering, and industrial control systems. These terms frequently appear in manuals, datasheets, design documents, and technical discussions. A clear understanding of these terms not only improves communication but also ensures accuracy in instrument design, selection, installation, calibration, and

In modern industrial environments—particularly in chemical plants and refineries—instrumentation technicians are no longer just responsible for installing and maintaining instruments. They are now expected to understand the broader process landscape in which these instruments operate. This article explains why process knowledge is critical for every instrumentation technician and to what level this knowledge should be
