2. Key Selling Points

1. High-Precision Continuous Level Measurement with FMCW Radar Technology: The LI5134 is a non-contact level sensor utilizing Frequency-Modulated Continuous Wave (FMCW) radar technology. Compared to traditional pulse radar, FMCW provides a higher signal-to-noise ratio and measurement resolution through continuous frequency modulation. It enables sub-millimeter high-precision measurement, even for low dielectric constant media (such as LPG, liquid ammonia, and organic solvents), ensuring reliable and stable data.
2. Optimized Design for Small and Complex Tanks: Its compact structure and small antenna size (typically a horn antenna) make it ideal for small tanks, metering vessels, reactors, or space-constrained installations. The precise microwave beam focusing effectively minimizes interference from tank walls, agitators, heating coils, and other internal structures, ensuring measurement accuracy in complex applications.
3. Exceptional Chemical Resistance and Robust Protection: The sensor housing and antenna are made of high-quality PPS (Polyphenylene Sulfide), offering excellent chemical resistance to various acids, alkalis, salts, and organic solvents. With an IP68/IP69K protection rating, it is fully dustproof and resistant to high-pressure water jets, high-temperature steam, and CIP/SIP (Clean-in-Place/Sterilize-in-Place) processes, making it suitable for harsh industrial and hygienic environments.
4. Integrated IO-Link Interface for Full Digital Smart Communication: Equipped with an IO-Link 1.1 interface for bidirectional digital communication. In addition to high-precision real-time level data, it provides complete echo curves, signal quality, device status, temperature information, and comprehensive diagnostic functions. Supports remote parameterization, firmware updates, and predictive maintenance, serving as a key component for Industrial IoT (IIoT) and digital production.
