Ring-11 Fork Level Switch: High-Reliability Industrial Level Measurement Benchmark
In today’s rapidly advancing industrial automation landscape, level measurement devices are no longer just “switch signals.” They are critical for ensuring production safety, process stability, and equipment efficiency. Shenzhen Jiwei Automations Ltd (hereafter “Jiwei”) has leveraged years of technical expertise and engineering experience to develop the Ring-11 Fork Level Switch, which is increasingly recognized as a benchmark for high-reliability industrial level measurement products.
The Ring-11 Fork Level Switch is a precision, high-reliability level measurement device. Its ultra-short fork design, measuring only 40mm in length, is suitable for tanks, vessels, and small containers, as well as narrow conduits and pipelines. The device provides accurate, long-term monitoring even in low-density liquids or challenging process conditions.
Precision Engineering for Advanced Measurement Capability
The Ring-11 operates on the principle of detecting vibration frequency changes when the fork is immersed in the medium. Precisely tuned, it can detect liquids with densities as low as 0.5 g/cm³, making it suitable for a wide range of applications including hydrochloric acid, sulfuric acid, nitric acid, alkaline solutions, syrup, pharmaceuticals, and industrial wastewater. It meets the rigorous level measurement standards required in chemical, pharmaceutical, food, and renewable energy industries.
Additionally, the Ring-11 demonstrates excellent performance in high-pressure liquefied gases (e.g., LNG). Even in the presence of foam, bubbles, viscous liquids, or pipeline vibrations, it delivers stable and accurate level signals, ensuring reliable control in complex operating conditions.
Innovative Design for Flexible Installation
Traditional level switches often struggle in narrow pipelines or conduits, where installation is difficult and measurement can be inaccurate. The Ring-11’s 40mm ultra-short fork overcomes these spatial constraints, enabling precise level detection in confined pipelines, conduits, and small tanks.
Its structural design also addresses sticking and adhesion issues. The integrated fork and optimized geometry reduce liquid, slurry, and grease retention, lowering false trigger risks and improving reliability in industrial operations.
Robust Anti-Interference Performance
Industrial level switches face numerous interferences: vibration, foam, bubbles, viscous liquids, and more. Ring-11 incorporates proprietary anti-interference technology, filtering environmental noise, low-frequency vibrations, and electromagnetic interference to maintain measurement accuracy.
This design allows for minimal on-site maintenance, reducing operational costs while enhancing overall equipment reliability.
Multiple Output Options for High Compatibility
Ring-11 offers four output types:
- Relay Output: Supports high/low level alarms and logic control for traditional switching systems.
- Two-Wire Output: Simplified wiring for long-distance transmission and fieldbus integration.
- NAMUR Output: Compliant with German industrial standards, designed for intrinsically safe or hazardous areas. Many competitors cannot provide NAMUR outputs, giving Ring-11 a clear advantage in high-safety applications.
- Transistor Output: High-speed, low-power, directly interfacing with PLCs or microcontrollers for rapid control and automation.
These versatile outputs enable seamless integration with PLC, DCS, SCADA, or independent alarm and interlock systems, while also supporting multi-channel monitoring and redundancy control for complex applications.
Authoritative Certifications for Reliable Operation
The Ring-11 Fork Level Switch has obtained multiple internationally recognized certifications:
- SIL2/3 Functional Safety
- 3C, CE, EAC
- Intrinsic Safety (Ex ia) and Explosion-Proof (Ex d)
These credentials ensure reliable operation in high-risk industrial environments, meeting the strict requirements of chemical, pharmaceutical, food, and energy sectors.
Ring-11 also holds a national invention patent (ZL201510735568.2), highlighting Jiwei’s technological innovation and engineering expertise.
High-Reliability Design for Extreme Conditions
Key advantages of Ring-11 include:
- Low-Density Liquid Detection: Precisely tuned for liquids ≥ 0.5 g/cm³.
- High-Temperature Resistance: Operates up to 400℃, suitable for chemical, petroleum, and pharmaceutical applications.
- Complex Process Adaptability: Stable signal output even in foam, bubbles, vibration, or viscous liquid conditions.
It is suitable for standard liquid applications and challenging scenarios such as acidic/alkaline solutions, syrup, pharmaceuticals, and industrial wastewater.
Extensive Field Applications Validating Reliability
Jiwei’s Ring-11 has been deployed across numerous industries:
