SLDL5228 High-Temperature High-Pressure Radar Level Meter
The SLDL5228 High-Temperature High-Pressure Radar Level Meter is a robust industrial-grade radar level sensor designed for the most challenging process conditions, including extreme heat, high pressure, heavy dust and strong interference. Using advanced 26GHz K-band microwave technology and a high-performance trumpet (parabolic) antenna, the SLDL5228 High-Temperature High-Pressure Radar Level Meter delivers non-contact, high-precision continuous level measurement for both liquids and solids. As part of the comprehensive SLDL5220 radar series, the SLDL5228 High-Temperature High-Pressure Radar Level Meter is ideal for demanding applications in oil and gas, refining, chemical processing, metallurgy and power generation, where reliability and accuracy under harsh conditions are critical.
Working Principle & Core Technology
The SLDL5228 High-Temperature High-Pressure Radar Level Meter operates on the time-of-flight principle, emitting high-frequency 26GHz K-band microwave pulses that reflect off the material surface and return to the antenna. The sensor calculates the exact distance based on the time delay, converting it into a stable level output. Its trumpet antenna design focuses the microwave beam tightly, minimizing interference from tank walls, internal structures and heavy dust. The SLDL5228 High-Temperature High-Pressure Radar Level Meter supports one-click false echo learning, which automatically identifies and suppresses unwanted reflections, ensuring accurate readings even in cluttered tanks with agitators, baffles or other obstacles.
