In some industrial environments, cable-related faults account for up to 50% of all system failures. Issues such as overloads, short circuits, and signal integrity loss frequently originate from poor-quality or improperly maintained cabling. For end users pursuing high-reliability automation, ensuring cable system integrity is mission-critical. 1. When and How to Evaluate Cable Quality A robust […]

Thermal power plants convert chemical energy into electrical energy through complex thermodynamic processes involving numerous mechanical and chemical reactions. To ensure the efficient, safe, and stable operation of power generation, thermal power plants must be equipped with a comprehensive range of process instruments. These instruments monitor, control, and adjust system parameters to ensure the normal

Introduction In recent years, the inspection cycle of Safety Instrumented Systems (SIS) and Distributed Control Systems (DCS) has become a focal point of discussion in China’s chemical industry. Unlike general industrial equipment maintenance, the periodic inspection of SIS and DCS is directly linked to a plant’s automatic protection and regulation capabilities—especially critical in high-risk environments

A potentiometer, often abbreviated as “pot”, is a type of variable resistor widely used in electronic and electrical circuits to adjust voltage or signal levels. It consists of a resistive element and a sliding or rotating contact (wiper) that taps the resistance to provide a variable output voltage. 1. Working Principle of a Potentiometer A
