Industrial instruments are becoming increasingly intelligent and precise. Modern flowmeters, pressure transmitters, radar level transmitters, analyzers, PLCs, and DCS I/O modules often contain sensitive electronic circuits that can be damaged by transient overvoltages. A surge may last only microseconds, but its voltage can rise far above the normal operating level. A single severe surge can

Many engineers have asked whether USB Type-C can be used as a power interface for industrial equipment, especially when the required current reaches 5A. From the perspective of interface structure and USB Power Delivery (PD) standards, supporting 5A current through USB Type-C is technically achievable. However, in real industrial products, the key question is not

A Practical Guide to Freeze Protection, Heat Tracing, Impulse Lines, Instrument Air and Outdoor Instrumentation Winter is one of the most challenging seasons for instrumentation engineers and maintenance technicians. As ambient temperatures drop, instrumentation systems that have operated reliably throughout the year may suddenly develop problems such as frozen impulse lines, failed heat tracing, blocked

In industrial automation and process control systems, 4-20mA current signals and 1-5V voltage signals are two widely used analog signal standards. According to IEC industrial signal transmission standards, field instruments typically use 4-20mA DC current signals for long-distance transmission, while control systems often use 1-5V DC voltage signals for signal processing and communication. This combination

Introduction In industrial boiler systems, the flame detector (also called a flame scanner) plays a critical role in monitoring combustion conditions and ensuring safe operation. By continuously detecting the presence and stability of the flame, the flame detection system provides essential feedback for safety interlocks, burner management systems (BMS), and combustion control. When a flame
