ARL5000 Series
The ARL5000 Series is a high-frequency radar level transmitter designed for non-contact level measurement in challenging environments. Utilizing 26 GHz microwave pulses, it delivers stable and accurate measurements with a range of up to 70 m (230 ft). The transmitter’s anti-interference capabilities make it unaffected by noise, vapor, dust, foam, or vacuum, ensuring reliability in harsh conditions. With a smaller beam angle and focused energy, it enhances radar echo and reflection on inclined solid surfaces. Its non-contact design eliminates wear and pollution, while its advanced microprocessor and optimized antennas ensure superior signal analysis and measurement accuracy of ±3 mm. Simple structure and easy installation make it ideal for various industrial applications.
