2. Key Selling Points- High-Precision, Non-Contact Measurement Based on FMCW Radar
Technology: The LI5141 is an advanced 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 accuracy through continuous frequency modulation, enabling millimeter-level high-resolution measurement. It ensures stable and reliable results even in challenging
conditions such as foam, condensation, or vapor on the medium
surface.
- Designed for Small Tanks and Space-Constrained Applications: Its compact design and small antenna size make it the ideal solution for small vessels, metering tanks, intermediate buffer tanks, or
industrial equipment with limited installation space. The compact form factor minimizes space requirements and
effectively reduces interference from internal structures (e.g.,
agitators, heating coils) on the microwave signal.
- Excellent Chemical Resistance and Robust Durability: The sensor housing and antenna are made of high-quality PPS (Polyphenylene Sulfide), offering outstanding chemical resistance to various acids, alkalis, salt solutions, and organic
solvents. With an IP68/IP69K protection rating, it is fully dustproof and resistant to prolonged water immersion,
high-pressure water jets, and high-temperature steam sterilization
(CIP/SIP), making it suitable for harsh industrial and hygienic
environments.
