Comprehensive Solution for Preventing Wire Breakage and Loose Connections in High-Frequency Vibration Environments

Instrumentation /

Introduction and Objectives Background: In industries such as chemical production, thermal power generation, metallurgy, and mining, equipment like pumps, coal mills, and turbines often generate high-frequency vibrations. These vibrations pose significant risks to the reliability of instrument wiring. Loose, improperly connected, or broken wires can cause measurement signal fluctuations and distortions, leading to false alarms, […]

Magnetostrictive Level Transmitter: Core Knowledge and Troubleshooting

Level meter /

Magnetostrictive level transmitters use the magnetostrictive effect (where a magnetic field causes a metal rod to undergo elastic deformation and generate ultrasonic waves) to provide highly accurate level measurements. The key advantages are non-contact measurement, high precision (typically ±0.1%), and excellent stability. These devices are widely used for level monitoring in closed or open containers

Why High Neck Valve Caps Are Not an Option, but a Necessity in Cryogenic Applications

Valve /

Cryogenic valves are widely used in industries dealing with extremely low-temperature media such as liquid oxygen, liquefied natural gas (LNG), and others. These media are not only highly flammable and explosive, but they also vaporize rapidly upon warming, causing a volume expansion of several hundred times, which creates significant safety risks. So, why are high

The “Golden Rule” for Installation Distance of Clamp-on Ultrasonic Flow Meters: Ensuring Accurate Measurement

Flow meter /

Clamp-on ultrasonic flow meters are non-invasive flow measurement tools, where the correct installation distance plays a critical role in ensuring measurement accuracy. Based on industry practices and technical standards, the installation distance must meet three core requirements: pipe straight length, interference avoidance, and sensor spacing. These factors are essential for ensuring stable signal transmission. 1.
