SLDL5200-81 Radar Level Transmitter

The SLDL5200-81 Radar Level Transmitter is a high-precision 78GHz W-band radar level sensor designed for continuous liquid level measurement in industrial tanks and process vessels. As a thread-mounted high-frequency radar transmitter, the SLDL5200-81 Radar Level Transmitter features a narrow 2° beam angle, ±0.5mm measurement accuracy and 0–120m range, delivering stable and reliable level data even in harsh environments. Developed by Solidat Applied Technologies Ltd., the SLDL5200-81 Radar Level Transmitter is part of a complete product family that includes cartridge, sanitary, lens and gimbal versions, meeting diverse industrial measurement needs.

Core Technology & Working Principle of SLDL5200-81 Radar Level Transmitter

The SLDL5200-81 Radar Level Transmitter adopts advanced 78GHz W-band frequency-modulated continuous wave (FMCW) technology, which emits high-frequency microwave signals that reflect off the liquid surface and return to the sensor. The transmitter calculates the exact distance based on the time-of-flight principle and converts it into a continuous 4–20mA or digital output signal. The narrow 2° beam angle ensures high directivity, making the SLDL5200-81 Radar Level Transmitter less susceptible to internal tank obstacles, foam, vapor and turbulence. Its one-click false echo learning function eliminates interference signals, ensuring accurate and stable readings even with condensation or material buildup on the antenna.
