IP Protection Rating DefinitionThe IP (Ingress Protection) rating defines the protection level of a product\u2019s enclosure against the intrusion of solid objects (such as tools, fingers, dust, etc.) and the ingress of water (from condensation, washing, immersion, etc.). The two digits following “IP” indicate the protection levels for solid objects and water intrusion.

In the application of electric actuators’ anti-interference performance, the 4-20mA analog signal significantly outperforms the 2-10V analog signal. Why is this the case? 2-10V Signal Analysis Anti-interference Diagram for 2-10V Signal (DCL Huayi Intelligent Control) As shown in the diagram above: When using 2-10V, due to the higher input resistance on the module (R=34K), the input signal current is very low (0.059mA – 0.29mA). The result is that the signal-to-noise ratio along this path is very low, which means the<\/p>\n\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Application Background of Process Control Actuators In many process control systems, it is necessary to achieve highly accurate and consistent control of the flow rate of liquids or gases through an automated control system (PLC\/DCS). Due to the high precision required, such systems often need to make continuous and precise small adjustments to control valves when implementing closed-loop control.

Butterfly Valve Working Principle: A butterfly valve uses a disc to control the flow of fluids or gases. The disc is mounted on a shaft, and when the handle is turned, the disc rotates 90 degrees to allow or block the flow. Features: Simple structure, compact size, low flow resistance, commonly used in large flow and low-pressure applications.
