Jiwei Vibrating Fork Level Switch: Setting a New 280°C Standard for Industrial Measurement
Shenzhen Jiwei Automations Ltd. is proud to announce the latest performance upgrade for its flagship product — the Ring-11 vibrating fork level switch. This new enhancement extends the operational temperature range to 280°C, enabling the device to function reliably in even more extreme conditions. This upgrade represents a significant milestone, positioning the Ring-11 as an industry leader in both reliability and environmental adaptability, particularly in high-temperature environments where few alternatives can perform at this level.

Ring-11: The New Benchmark for Level Measurement Technology
The Ring-11 is an intelligent level control switch designed for use in various containers, tanks, silos, and pipelines. It finds widespread application in industries such as water resources, chemical engineering, environmental protection, food, and pharmaceuticals. The core technology of the Ring-11 is based on the piezoelectric principle, where the vibrating fork vibrates through a piezoelectric element. Upon contact with the liquid, the vibration frequency changes due to the damping effect of the liquid, and this change is detected and converted into a stable switching signal. This design eliminates the need for onsite adjustments, ensuring simple and reliable operation.

The Ring-11’s compact design, with a fork length of just 40mm, makes it especially advantageous for space-constrained environments, such as pipelines where space for equipment is limited. This compact design does not compromise its performance. The vibrating fork level switch offers excellent stability and detection capabilities even in challenging conditions such as foam, bubbles, viscous liquids, and strong vibrations, which often disrupt traditional sensors. Its ability to measure materials with a minimum density as low as 0.5g/cm³ ensures that it meets the diverse needs of industries requiring precise liquid and solid level measurement.
Industry-Leading Durability and Safety Features
One of the key highlights of the Ring-11 vibrating fork level switch is its exceptional durability, especially its high-temperature resistance. The device now operates stably in temperatures up to 280°C, making it suitable for use in extreme environments such as steam, hot oil, and chemical reactions. Whether in industrial settings with extreme heat or in other challenging applications, the Ring-11 vibrating fork level switch maintains its superior performance, providing a level of dependability that few other level switches can match.

Additionally, the Ring-11 vibrating fork level switch has earned SIL2/SIL3 functional safety certification and is equipped with both intrinsic safety and explosion-proof certifications. These certifications ensure that the device can be safely used in high-risk applications, offering critical protection in industries where safety is paramount. These features make the Ring-11 a trusted choice for hazardous and volatile environments, including chemical plants, petrochemical industries, and pharmaceutical manufacturing.
