Radar level sensors<\/strong> ensures accurate and reliable continuous measurement of material levels in various containers and processes. The measurement principle is based on electromagnetic waves: the sensor emits a focused wave that is reflected from the surface of the material and returns to the sensor as an echo, where it is processed.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

Operation of radar sensors<\/strong> based on electromagnetic waves. The sensor emits a focused signal that is reflected from the surface of the material and returns as an echo signal to the device, where it is processed and converted into a level value. This category includes both free-beam radars and guidance radars, also known as TDR<\/strong> or GWR<\/strong> sensors.<\/p>

The fundamental difference between these technologies lies in the signal transmission. Free-beam radars use antennas that send waves in a non-contact manner towards the material, while guided radars transmit the signal through a probe \u2013 a rod or cable \u2013 that is in direct contact with the material.<\/p>

Free-radiating radars<\/strong> are usually described by operating frequency, as it is this that determines accurate and reliable level measurement in various containers.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

\u00a0High-frequency technology allows for more compact sensors, narrower beam angles, and better reflection properties. For these reasons, UWT radar sensors<\/strong> works with modern 80 GHz technology<\/strong>, which guarantees extremely precise results.<\/p>

Directional radars, on the other hand, can operate at a much lower frequency, around 1 GHz. This technology is particularly useful when the environment contains dust, sediment, foam, vapors or when the measured surface is unstable. In addition, these sensors are also suitable for determining phase boundaries (interfaces). An important part of them is the probe - depending on the application, you can choose a rod, cable, coated cable (PA) or coaxial version. This allows UWT for radar solutions<\/strong> adapt to various industrial needs and ensure accurate and reliable level measurement.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

Continuous level measurement with non-contact radars<\/h2>

Non-contact radar sensors<\/strong> <\/a>uses FMCW technology<\/strong> (76-84 GHz), which allows precise distance determination based on the difference in frequency between the transmitted and reflected signal. This allows the filling level to be calculated without direct contact with the material.<\/p>

These radars are suitable for both liquids<\/strong>, both bulk materials<\/strong> for level measurement. They are reliable, resistant to dust, steam or temperature fluctuations and require no maintenance.<\/p>

UWT 80 GHz radar sensors<\/strong> ensures a narrow beam angle and highly accurate results even in difficult conditions.<\/p>

Due to their contactless operating principle, they are ideal for situations where:<\/p>
