Instrumentation

Temperature sensors are widely used in industrial automation, process control, medical equipment, and household applications. They play an important role in monitoring and controlling temperature in various systems. However, temperature sensors may experience inaccurate readings, unstable signals, or complete failure due to electrical problems, environmental conditions, improper installation, or aging components. Understanding the common causes […]

In industrial automation systems, wiring short circuits are one of the most common electrical faults that can cause instrument failure, signal interruption, equipment damage, or even safety risks. A short circuit occurs when two points in an electrical circuit that should remain separated become unintentionally connected. This creates a low-resistance path, causing excessive current flow

Introduction For engineers working on Safety Instrumented Systems (SIS), one question will eventually come up: What SIL level is required for this SIF loop? Safety Integrity Level (SIL) is a key parameter used to define the risk reduction capability of a Safety Instrumented Function (SIF). It determines the required reliability level of safety-related components, including

Understanding Thread Sealing Requirements for Explosion-Proof Conduit and Cable Gland Connections During explosion-proof electrical inspections, engineers often find the same installation practice: PTFE thread tape (commonly known as thread seal tape) is wrapped around galvanized conduit threads, and sometimes it is also applied to explosion-proof cable gland threads. The reason given by installers is usually

Introduction Resistance measurement is one of the most common troubleshooting methods used by instrumentation and maintenance engineers. By measuring resistance values, engineers can quickly determine whether an instrument component is working properly, such as: RTD temperature sensors (PT100/PT1000) Solenoid valve coils Vibration sensors Instrument cables Sensor insulation conditions However, many field technicians are confused about

Summer Instrument Maintenance: Why High Temperature Can Be Just as Dangerous as Freezing Weather When summer arrives, people feel the heat — but industrial instruments often suffer even more. Under continuous sunlight exposure, high ambient temperatures, and frequent thunderstorms, many instrumentation problems that rarely appear in winter can suddenly emerge during the hot season. Many

Do Emergency Shutdown Valves Always Need Fireproof Covers? For emergency shutdown valves (ESD valves), the installation of a fireproof cover is often a topic of debate. Some engineers believe that fireproof covers are mandatory for all ESD valves, while others believe that a spring-return actuator with a fusible plug is sufficient in many applications. So,

Anyone who works with field instrumentation has probably encountered this situation: The impulse line is almost blocked, yet the pressure trend on the DCS still looks stable and the reading appears normal. Then the process condition changes—and the problem suddenly becomes obvious. The actual process pressure has already increased, but the DCS value is still

Why Choosing the Right Sealing Method Matters In industrial instrumentation systems, many leakage problems appear to be caused by loose connections. However, when investigated carefully, the real problem is often that the wrong sealing method was selected from the beginning. Instrument air tubing, impulse lines, process connections, valve manifolds, and cable entries may all require

Introduction Hazardous chemicals are widely used in industries such as chemical processing, oil and gas, pharmaceuticals, mining, water treatment, and manufacturing. Due to their potential risks, improper handling, storage, or transportation may result in fire, explosion, toxic exposure, environmental pollution, or serious safety incidents. Before hazardous chemicals are stored in a warehouse or process area,
