1. Introduction
The Flexible Cable Vibrating Rod Level Switch is a high-precision level measurement instrument designed specifically for granular and powdery solid materials. Thanks to its innovative structure and advanced features, this sensor delivers stable and reliable level detection in complex industrial environments. Its exceptional adaptability and durability have made it a preferred choice in industries such as power generation, chemical fertilizer, metallurgy, and food processing.
2. Innovative Design: Dual-Probe Structure with Flexible Cable
This level switch adopts a dual-probe design—a domestic innovation—which effectively prevents material adhesion and clogging during operation. The use of flexible cable instead of a rigid rod allows for installations up to 20 meters in length, accommodating tall silos and remote monitoring needs.
Compared to traditional rod-style sensors, the flexible cable design minimizes pressure from bulk materials during flow, significantly reducing mechanical wear and extending service life.
3. High Sensitivity and Broad Compatibility
With finely tuned probes and high sensitivity, this device can accurately detect materials with bulk densities as low as 0.02 g/cm³. It performs exceptionally well in diverse industrial applications:
Coal-fired power plants: Efficiently measures CaSO₄ and CaSO₃ in semi-dry desulfurization silos, solving sticking-related issues.
Biomass fuel silos: Reliably detects light materials such as sawdust and straw pellets under extreme conditions.
4. Excellent Adaptability & Self-Diagnostic Capabilities
The switch is designed to maintain stable performance despite high humidity, variable dielectric constants, or challenging installation environments. It also features self-diagnostic functionality, allowing real-time health monitoring and fault localization. This reduces downtime and maintenance costs, increasing system uptime and reliability.
5. Certified Safety for Hazardous Environments
To meet safety standards in explosive or flammable environments, the level switch is certified for:
CE compliance
Dust-proof and gas-proof explosion protection
Ex d IIC T6～T1 Gb (flameproof for gases)
Ex ia IIC T6～T1 Ga (intrinsically safe for gases)
These certifications ensure safe and stable operation even in hazardous industrial zones.
6. Superior Durability in Harsh Conditions
Constructed with corrosion-resistant materials such as 316L stainless steel and 318S13 alloy, the sensor performs reliably in high-temperature, high-humidity, and corrosive environments. This robust construction minimizes failure rates and ensures long-term operation.
7. Industry Applications
The flexible cable vibrating rod level switch is widely used across multiple sectors:
| Industry | Application Scenarios |
|---|---|
| Power Generation | Coal silos, biomass fuel storage, desulfurization product silos |
| Fertilizer Plants | Urea, phosphate, and other granular chemical material bins |
| Metallurgy | Alumina silos, raw material storage, smelting furnaces |
| Food Industry | Grain warehouses, flour silos, powder handling systems |
| Wastewater Treatment | Sedimentation tanks for sludge level monitoring |
8. Conclusion
With its advanced dual-probe design, exceptional measurement accuracy, and robust safety certifications, the Flexible Cable Vibrating Rod Level Switch is a reliable tool for modern industrial level control. Whether deployed in demanding metallurgical plants or strict chemical processing lines, this switch delivers consistent performance, driving the transition toward smarter and safer industrial automation.
