Jiwei Develops China’s First Dual-Tube Vibrating Rod Level Switch, Advancing Industrial Level Measurement
In today’s era of industrial automation and smart manufacturing, level measurement remains a critical component of process control. Since 2013, Shenzhen Jiwei Automations Co., Ltd. (“Jiwei”) has been dedicated to researching and developing advanced vibrating rod level switches to address increasingly complex and variable working environments. Especially in the precise level control of powders and granular materials, the demand for sensors with higher sensitivity, stability, and interference resistance has steadily risen. Recently, Jiwei achieved a major breakthrough by successfully developing China’s first dual-tube design vibrating rod level switch, offering a highly reliable, precise, and cost-effective solution for industrial applications.
Jiwei’s Breakthrough: Dual-Tube Design Enhances Vibration Performance
Traditional vibrating rod level switches typically use a single probe design, which often faces challenges such as slow response, false alarms, and susceptibility to dust interference when applied to lightweight or low-density materials. Jiwei’s newly developed vibrating rod level switch innovatively adopts an “inner-outer nested dual-tube design”, where two coaxial vibrating tubes generate a resonant effect during operation. This significantly improves vibration amplitude stability and signal recognition capability.
This design not only strengthens vibration signal amplitude and consistency but also greatly improves detection sensitivity. The device reliably triggers at material bulk densities as low as 0.02 g/cm³, marking a technological leap that fills a domestic gap in low-density material detection and challenges long-standing dominance by foreign brands.
Engineered for Harsh Industrial Conditions with Superior Adaptability
Jiwei’s vibrating rod level switch is engineered specifically for industrial environments characterized by heavy dust, intense vibrations, and strong electromagnetic interference. It offers outstanding sensitivity, reliability, and false alarm resistance. Typical applications include:
- Raw material silos and hoppers in cement, lime, and gypsum industries
- Intermediate storage silos in food sectors such as grain, feed, and flour
- Powder measurement and storage in chemical plants
- Level monitoring in lithium battery, metallurgy, and mining industries with high dust and corrosive conditions
By optimizing both mechanical structure and electronic components, Jiwei’s product maintains stable operation even under challenging conditions, effectively preventing false signals caused by material adhesion or dust buildup.
Leading Domestic Alternative to Imported Vibrating Rod Switches
Currently, the Chinese market largely depends on imported vibrating rod level switches from companies like VEGA, Endress+Hauser, and UWT. Compared with these brands, Jiwei’s vibrating rod level switch shows clear advantages:
| Feature | Imported Switches | Jiwei Dual-Tube Switch |
|---|---|---|
| Vibration Structure | Single Tube | Dual-Tube Resonance Design |
| Minimum Detection Density | ~0.05 g/cm³ | As low as 0.02 g/cm³ |
| Response Speed | Relatively Slow | Rapid Response |
| Dust Interference Resistance | Moderate | Strong |
| Price | High | Cost-Effective |
| Service & Support | Longer Lead Times | Localized, Fast Response |
The combination of superior performance and competitive pricing not only enables Jiwei’s product to replace imported switches domestically but also delivers more flexible, customer-centric service.
Commitment to Innovation Fuels Intelligent Manufacturing
As a leading provider of level measurement solutions in China, Jiwei Automations continuously pursues innovation. The company offers a comprehensive range of high-performance level control products including RF admittance level switches, tuning fork level switches, and radar level meters. The successful development of the dual-tube vibrating rod level switch exemplifies Jiwei’s commitment to vertical industry focus and aligns with China’s national “Made in China 2025” initiative.
Jiwei has filed multiple national invention and utility model patents for this product. Future plans include expanding its use to demanding environments with high dust levels, frequent material flow, and stringent response time requirements. Moreover, Jiwei is developing smart features such as HART protocol compatibility, Bluetooth-based configuration, and remote maintenance via mobile applications, pushing vibrating rod level switches toward intelligent sensor solutions.
Strong Market Reception and Broad Application Prospects
Since internal testing, Jiwei’s dual-tube vibrating rod level switch has been trialed by several industry leaders in cement manufacturing, lithium battery cathode material production, automated batching systems, and grain processing plants. Feedback confirms stable performance, low false alarm rates, and ease of maintenance, earning high praise from end users.
With its broad applicability, robust adaptability, and attractive price-performance ratio, the product is poised for rapid adoption in both domestic and international markets, establishing itself as a benchmark in China’s vibrating rod level switch segment.
Conclusion: Driving the Rise of Domestic Innovation and Industry Leadership
From integrated vibration structures to advanced dual-tube nested resonance designs, Jiwei Automations consistently leads the frontier of China’s high-end level measurement technology. This innovative vibrating rod level switch breakthrough not only demonstrates the strength of domestic R&D but also signals the maturation of Chinese level measurement equipment into a new era characterized by high sensitivity, enhanced stability, and smart capabilities.
