In modern automated production lines, many precise and repetitive mechanical actions rely on a component that rarely attracts attention: the pneumatic cylinder.From stamping presses and robotic arms to packaging systems and electronic assembly equipment, pneumatic cylinders silently convert compressed air into controlled motion, forming the muscle system of machinery. 1. What Is a Pneumatic Cylinder?

Radar level transmitters have become one of the most reliable technologies for liquid and solid level measurement. With advantages such as non-contact measurement, high accuracy, strong anti-interference capability, minimal maintenance, and long service life, radar instruments are now widely used across process industries. Among various radar frequencies—6GHz, 26GHz, 80GHz, and even 120GHz—the 26GHz and 80GHz

In gas detection and safety-instrumented applications, the choice of signal transmission method is not just a design preference—it directly affects the Safety Integrity Level (SIL) and the overall reliability of the safety protection layer. As fieldbus technologies become more common in process plants, a frequently debated question has emerged: Can a Gas Detection System (GDS)

According to GB 50493 (Design Standard for Combustible and Toxic Gas Detection and Alarm Systems) and general industrial safety design practices, GDS detection units must use independent point-to-point wiring when transmitting signals to the alarm controller.Bus (multi-drop shared line) communication is not permitted for safety-critical gas detection functions. The core purpose of a GDS is

In modern industrial automation, digital communication protocols such as Modbus, Profibus, and HART have become increasingly popular. Yet, despite these advances, the 4–20 mA analog signal remains one of the most reliable and widely used methods for transmitting process variables such as pressure, temperature, flow, and gas concentration. From gas detection systems (GDS) to level
