Vergelijking van de storingsbestendigheid: 4-20mA versus 2-10V

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 […]

Veelgebruikte bussen voor elektrische actuatoren

An increasing number of industrial control systems are deploying field buses to control more sensors and actuators. As a key actuator in fluid control processes, electric actuators are commonly used in industrial applications. The most frequently used bus systems for electric actuators include Modbus, CAN, Profibus, DeviceNet, Foundation Fieldbus, HART, and Ethernet. Common Bus Systems […]

EN15714-2 Classificatie van elektrische actuatorbesturing (bedrijfseenheid)

Control Duty Classifications: Class A: ON-OFF Type (On/Off) Function: The actuator is required to drive the valve through its entire stroke from fully open to fully closed (and vice versa). Typical Use: Applications where valves are either fully open or fully closed. Class B: Fine-Tuning/Positioning Adjustment Type Function: The actuator occasionally moves the valve to […]

Wanneer moet je een procesbesturingsactuator kiezen?

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 […]

Elektromagnetische interferentietesten voor elektrische actuatoren (EFT)

De steeds veeleisendere elektromagnetische omgeving op industriële locaties Naarmate de elektrificatie en intelligentie in de industrie zich verder ontwikkelen, worden steeds meer krachtige elektrische apparaten (zoals motoren van kilowattniveau, frequentieomvormers en inverters) geïntegreerd in industriële procesbesturingssystemen. Hierdoor wordt de elektromagnetische omgeving op industriële locaties steeds complexer. In zo'n uitdagende elektromagnetische omgeving […]

Veelvoorkomende soorten kleppen en hun kenmerken

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 […]

Beschermingsclassificaties van behuizingen (UL, CSA, NEMA)

The protection ratings for enclosures defined by UL, CSA, and NEMA are categorized as follows. While the classifications are generally similar, there are minor differences in the details, so it is advisable to refer to the specific standards for more precise information. Type Classification Definition 1 General For indoor use, providing protection for enclosed components […]

IP-classificatie voor stof- en waterdichtheid van de actuator

IP Protection Rating DefinitionThe IP (Ingress Protection) rating defines the protection level of a product’s 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. The first […]

Hoe actuatoren met busfuncties werken – Modbus, CAN, Ethernet, Profibus

 Wanneer u een DCL-regelklep met busfunctionaliteit op een pijpleiding installeert, kunt u een set regelkleppen via de bus (Modbus, CAN, Ethernet, Profibus) aansturen om een gesynchroniseerde aansturing van het kleppencluster te realiseren. Het besturingssysteem communiceert met de actuator via een buscommunicatieprotocol en verzendt commando's om de klep aan te sturen.
