Breakthrough 400°C Liquid Level Switch — Jiwei Ring-11
Shenzhen Jiwei Automations Ltd. officially announces the release of the Ring-11 Ultra-High Temperature Liquid Level Switch, designed specifically for demanding high-temperature process control applications. This advanced instrument reliably operates in process temperatures up to 400°C, addressing a long-standing challenge in industrial measurement: traditional tuning fork level switches often fail or lose accuracy under extreme heat. The launch of Ring-11 not only broadens the application scope of tuning fork-based liquid level measurement devices but also marks a significant breakthrough in domestically produced instruments successfully substituting imported products for critical high-temperature environments. This advancement promotes autonomous control over high-temperature liquid level measurement and enhances China’s industrial measurement capabilities.
Structural Innovation and Rigorous Testing Ensure Ring-11 Liquid Level Switch Stability
Building on the proven Ring-11 series, Jiwei has optimized the design of the ultra-high temperature model to meet extreme environmental demands. The key innovation lies in the sealed cooling chamber integrated with precision copper capillary tubes, which channel cooling gas or water directly to the vibrating probe area. This effectively protects crucial internal components, such as the piezoelectric ceramic plates and sensitive wiring, from thermal degradation.
By maintaining the internal critical components’ temperature below 250°C, even when the external environment reaches 400°C, the Ring-11 guarantees stable vibration responses and reliable output signals. This design ensures that the device performs consistently without signal drift or failure in harsh thermal conditions.
During the development phase, Jiwei’s R&D team constructed a comprehensive high-temperature simulation system and subjected prototypes to continuous 72-hour endurance tests at multiple temperature gradients: 300°C, 360°C, and 400°C. These tests verified the effectiveness of the cooling system and the overall thermal management strategy. The data confirmed that the temperature within the probe area remained within design limits throughout, with zero thermal failure, proving the product’s robustness.
Proven Performance of Ring-11 Liquid Level Switch Across 300°C to 400°C
The Ring-11’s successful long-term testing at various high-temperature points offers solid engineering data, instilling confidence in its deployment across demanding industrial applications. This extensive verification underscores the instrument’s suitability for critical processes requiring precise and reliable liquid level control under ultra-high temperatures.
Core Technical Highlights
- Ultra-High Temperature Adaptability (Up to 400°C)
The Ring-11 employs an innovative cooling system allowing for stable operation in environments up to 400°C. This capability fills a significant gap in the domestic market, where few devices can withstand such extreme conditions. - Precision Copper Capillary Cooling Channels
Copper capillary tubes deliver cooling media with high accuracy directly to sensitive probe components. This keeps piezoelectric elements below 250°C, preventing depolarization and ensuring signal integrity. - Flexible Dual Cooling Options (Air or Water)
The device supports both gas and water cooling media, providing flexibility to users who can select the most convenient or effective cooling method based on site conditions. This design also simplifies installation and ongoing maintenance. - High-Temperature Sealing Design
The interface between the cooling channel and measurement chamber is sealed with materials designed to withstand high temperatures, ensuring long-term gas-tight integrity and operational reliability. - Comprehensive Stability Verification
Multiple test cycles with varying temperature gradients and cooling flow rates have validated the product’s performance, supported by solid engineering evidence. - Compact and Reliable Structural Optimization
Integration of the probe and cooling chamber results in a compact design featuring high vibration efficiency and strong immunity to external interference.
