Why Jiwei’s SIL2/SIL3 Tuning Fork Level Switches Are the Best Choice for High-Safety Applications
Level switches are crucial components in industrial automation systems, ensuring accurate and reliable monitoring of fluid levels in various applications. When dealing with critical processes, the safety and performance of level switches are paramount. SIL (Safety Integrity Level) certifications, such as SIL2 and SIL3, are industry standards that guarantee the safety and reliability of safety instrumented systems (SIS). In this article, we’ll explore why Jiwei’s SIL2/SIL3 certified tuning fork level switches are the optimal choice for industries requiring precision, safety, and durability.
What is a SIL Level Switch?
A SIL level switch is a device designed to meet stringent safety standards (IEC 61508/IEC 61511) that ensures a certain level of risk reduction in industrial processes. These switches are critical in industries such as chemical, oil and gas, and power generation, where hazardous materials or dangerous conditions are present. Achieving a high SIL rating indicates the switch’s reliability and ability to operate safely under extreme conditions.
Why Choose Jiwei’s Tuning Fork Level Switch?
Jiwei’s tuning fork level switches, particularly the Ring-11 model, are engineered to provide exceptional performance in a variety of challenging environments. Below are some key features that make Jiwei’s SIL2/SIL3 certified tuning fork level switches stand out:
1. 40mm Fork Length – Ideal for Tight Spaces
Designed with a 40mm fork length, Jiwei’s Ring-11 tuning fork level switches are perfect for installations in confined spaces and pipelines. These dimensions ensure that the switch fits easily in environments where space is limited, without compromising performance.
2. High Sensitivity for Low-Density Media
The high sensitivity of the Ring-11 switch is one of its key advantages. With its harmonic resonant frequency precisely pre-adjusted, it can detect media with a density as low as 0.5g/cm³. This makes it suitable for applications involving low-density liquids or powders.
3. Strong Anti-Interference Capability
Jiwei’s Ring-11 is designed to resist common challenges in industrial environments, such as foam, bubbles, viscosity, and oscillations. This ensures reliable and consistent performance, even in liquids with fluctuating properties.
4. Corrosion-Resistant Materials
For high-temperature applications, the Ring-11 is available with Hastelloy C-22 material, which is highly resistant to corrosion and erosion. This makes the device ideal for harsh environments where exposure to aggressive chemicals or high temperatures is common.
5. High-Temperature Performance
The Ring-11 operates efficiently at process temperatures up to 280°C, providing reliable level measurement even in high-temperature processes, such as in the chemical and power industries.
6. Flexible Output Options
The Ring-11 offers versatile output choices including relay, two-wire, NAMUR, and transistor outputs. This flexibility ensures easy integration into a wide range of control systems and applications.
7. SIL2/SIL3 and Intrinsic Safety Certifications
One of the most important aspects of Jiwei’s Ring-11 is its compliance with SIL2/SIL3 safety standards as per IEC 61508. This certification guarantees that the switch can be safely used in critical processes where failure could result in significant risk. Additionally, the Ring-11 is certified for Intrinsic Safety and Explosion-Proof protection, making it suitable for hazardous areas.
8. CE Certified for European Standards
Jiwei’s Ring-11 tuning fork level switches meet the rigorous safety and environmental standards set by the CE certification, ensuring compliance with European regulations for product safety and environmental impact.
