KLD803 Radar Level Sensor for Steam and Foam Measurement
Introduction
The KLD803 Radar Level Sensor, an ultra-high frequency radar instrument operating at 80GHz, offers non-contact measurement for both liquid and solid media. It is capable of accurately measuring a wide range of liquid substances, even under high pressure and extreme temperatures, such as solvents, corrosive substances, and hygienic fluids. Additionally, it reliably measures both light and heavy solids, unaffected by dust, noise, adhesion, or condensation, ensuring stable and accurate readings in challenging environments.
The 80G radar level sensor utilizes Frequency Modulated Continuous Wave (FMCW) technology, transmitting a high-frequency radar signal that continuously modulates in frequency through its antenna. The signal is reflected off the medium and received by the antenna as an echo, with the frequency shift being proportional to the distance. This shift is then converted into a level measurement for the material.
Feature
- Non-contact Measurement This technology ensures that the measurement is unaffected by variations in the medium’s properties or process conditions, including temperature, pressure, or dust levels. Additionally, it simplifies setup by eliminating the need to fill or empty containers, which speeds up instrument start-up and reduces maintenance needs.
- Wide Measurement Range with Minimal Blind Zone The sensor covers a measurement range from 0.1 to 120 meters, meeting most field measurement requirements effectively.
- Compact Antenna with Narrow Beam Angle and Strong Focus The small antenna size and narrow beam angle make installation easier, while its strong focus ensures excellent performance even in challenging environments, such as tanks with agitators, heating coils, or baffles, as well as in straight piping.
- High Accuracy The sensor offers an impressive accuracy of ±1 mm, ensuring precise measurements for applications in non-metering field conditions.
- Short Signal Wavelength With a short signal wavelength, this sensor excels at measuring the levels of fine powders, particles, and similar materials.
