Application of the SOLDO SW Series Transponder in Intelligent Control Systems in Oil Platforms and the Energy Industry

Application of the SOLDO SW Series Responders in Intelligent Control Systems for Oil Platforms and the Energy Industry.

Zhuhai Sevicon, in multiple automation projects, has extensively integrated SOLDO SW series feedback devices and, in combination with the practical requirements of 4-20mA Hart, has developed a stable, efficient, and remotely monitorable valve control solution.

1、Structural Design and Core Advantages of the SW Series Feedback Device.

The SOLDO SW Series 4-20mA Hart is a highly reliable industrial valve position feedback device. Its housing design fully considers the extreme operating environment requirements such as explosion-proof, waterproof, and corrosion resistance. The specific advantages are as follows:

Explosion-proof structure: Certified by ATEX/IECEx, suitable for Zone 1 and Zone 2 hazardous areas;

High protection level: IP66/IP68 protection, capable of long-term operation outdoors or in humid environments;

Optional stainless steel or aluminum alloy housing with polyester powder coating, providing excellent corrosion resistance;

Precision mechanical cam structure, easy to adjust, accurate positioning;

Diverse electrical interface support: NPN/PNP proximity switches, SPDT micro switches, solid-state outputs, etc.

The SOLDO SW Series products are particularly suitable for high-risk, high-frequency start-stop operating conditions and are especially applicable to systems that require high accuracy and durability in position indication.

2、Practical Application of SOLDO SW Series Products in the Integration of Offshore Oil Platforms and Intelligent Energy Control Systems

As a professional service provider in fluid control and automated valve systems, Zhuhai SEVICON widely applies the SOLDO SW series products in the following scenarios:

1.Chemical and Offshore Anti-Corrosion Projects

In highly corrosive environments, the SW series with 316L stainless steel housing is selected, combined with SEVICON\\\'s intelligent service control system, to achieve integrated control of multiple pneumatic valves, realizing energy savings and adaptation to high-strength operating conditions.

3、Key Points for Installation and Surge Protection

In SEVICON\\\'s project delivery standards, the installation of SOLDO SW series feedback devices on safety-critical valve equipment requires comprehensive surge protection and electromagnetic compatibility design to ensure signal stability and system longevity:

Mounted on a 35mm standard rail, facilitating system layout and maintenance;

SPD installed at the front end of the signal line to protect the SW signal module from lightning and surge interference;

All equipment is connected to equipotential bonding to reduce loop induction risks;

Power and communication cables are reasonably distributed to avoid crosstalk interference;

Multi-level protection coordination schemes are incorporated in the control cabinet design to protect downstream PLCs and actuators from voltage surges.

4、SEVICON\\\'s one-stop valve control solution.

Zhuhai Sevicon not only provides high-quality valve position feedback devices such as the SOLDO SW feedback transmitter, but also tailors solutions according to project requirements,

Provide a complete automation solution, including:

Actuator selection and installation support;
