During routine field inspections, pressure gauges are always one of the key checkpoints. Inspectors usually look for questions such as: Does the pointer return to zero? Is the calibration label still valid? Is the seal intact? Is there a red mark on the dial? Most people understand the first few items. But when it comes […]

Introduction For industrial level measurement engineers, two challenging applications often require special consideration: high-precision level measurement and extreme high-temperature process conditions. Many users are confused when selecting radar level transmitters. A common misunderstanding is that a high-frequency radar transmitter can automatically handle high-temperature applications, or that a high-temperature radar can provide the same measurement accuracy
In industrial pressure measurement, many engineers focus only on pressure range, output signal, or installation size, while overlooking one critical factor: Should the application use a gauge pressure transmitter or an absolute pressure transmitter? In many normal applications, a gauge pressure transmitter is completely sufficient. However, in some special operating conditions — especially vacuum, low-pressure,
Engineers see this kind of problem all the time: The sensor LED is ON, but the PLC input never changes. The relay clicks normally, but the equipment refuses to start. A fire alarm system suddenly reports false alarms after wiring. Even worse — an input module burns out immediately after connection. At first glance, these

During plant commissioning, engineers often encounter a frustrating situation: The pressure gauge is new.The temperature sensor is new.The flow meter has been factory calibrated. Yet once the system starts running, the readings become unstable. Flow fluctuates unexpectedly.Pressure jumps up and down.Temperature values no longer reflect the real process condition. Many people first suspect instrument quality
Practical Anti-Vibration Solutions for Instrumentation Panels and High-Vibration Environments Applicable for: M3 / M4 / M5 screw terminals Typical environments: DCS cabinets, PLC panels, MCC cabinets, vibration-prone industrial installations Introduction In many industrial plants — especially chemical, power generation, steel, mining, and water treatment facilities — DCS control cabinets are often installed close to: Pumps

In industrial sites, there is one situation technicians dread the most: The equipment suddenly stops.The breaker trips.The motor feels extremely hot.And when you open the electrical cabinet, there is already a burnt smell inside. Some people say it’s an overload.Others call it overcurrent.And someone immediately insists it must be a short circuit. They all sound

Radar level transmitters are widely used in aggressive chemical applications such as strong acids, alkalis, solvents, pharmaceutical liquids, and corrosive process tanks. But in real projects, one question often comes up: Why is PTFE sufficient in some radar level applications, while others specifically recommend PFA? Many people assume: “PFA is more expensive, so it must

Many people think dust is just a housekeeping problem — dirty floors, clogged equipment, or poor workshop conditions. But in industries handling combustible powders, dust can become far more dangerous. When fine particles become suspended in the air and encounter sparks, static electricity, hot surfaces, or friction heat, what looks like an ordinary layer of
Project Background A customer in Taiwan required two inline thermal mass flow meters for industrial gas monitoring applications. The project involved different gases and operating conditions, including nitrogen (N₂) and natural gas measurement. The customer required: Stable low-flow gas measurement Compact inline installation RS485 communication Explosion-proof protection Local LCD display with totalizer High temperature resistance
