1. Introduction In smart grain storage systems, temperature and humidity transmitters play an essential role in ensuring the safe and effective preservation of stored grain. Among all monitoring factors in a grain silo, controlling the internal temperature and humidity is of utmost importance. These two environmental parameters directly impact the quality, safety, and shelf life […]

Overview of Instrument Tube Fittings Common fitting types: Straight union Elbow union Tee union Union with swivel nut Adapter Plug Transition fitting Pipe Thread Standards: Thread Type Angle & Description Standard NPT 60° tapered thread ANSI/ASME B1.20.1 PT 55° tapered thread (Japanese standard) JIS B 0203 G 55° parallel (non-sealing) thread ISO 228 1/4″,

1. Introduction As industrial processes evolve, hazardous substances such as flammable gases, vapors, dusts, and fibers are commonly present in production, processing, storage, and transportation.Explosion accidents, if not prevented, can lead to equipment damage, production downtime, and even severe casualties. To mitigate such risks, the concept of hazardous area zoning and classification has become a

In the world of industrial instrumentation, experience is not measured by years alone. You could work for ten years and merely repeat the first year’s experience nine times. Or, you might master the essentials in just three years, handling projects independently, thinking systematically, and solving problems methodically. Just like many other industries, instrumentation places heavy

1. Overview In industrial environments, proper installation of combustible and toxic gas detectors is essential for early leak detection, personnel safety, and fire/explosion prevention. This guide provides standard recommendations for installation height, spacing, positioning, and alarm thresholds. 2. Detector Placement Principles The layout of detectors should be based on gas dispersion patterns after a leak.

1. Introduction This guide provides detailed instructions for using a digital multimeter in typical industrial scenarios, such as current loop measurement, RTD and thermocouple testing, and voltage measurements. Emphasis is placed on safety, accuracy, and practical steps for on-site diagnostics. 2. Measuring 4–20 mA Current Loop Signals Method 1: Break-Point Series Measurement Ensure the loop

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
