Until now, the following was true: With a radar sensor with a 26 GHz transmission frequency and an antenna size of 80 mm, the opening angle is approximately 10 °. With the Vegapuls 64, the beam angle for this antenna size is only 3 °. As a result, the sensor can be used even in very narrow shafts in which various pipes are located. The radar beam simply passes the obstacles.

Large dynamic range offers high measurement accuracy

The larger the dynamic range for radar sensors, the wider the range of applications for the sensors and the higher the measurement reliability. So far, there is no radar sensor for liquid applications on the market that covers a dynamic range similar to that of the Vegapuls 64. This means that media with low reflection properties, i.e. low dielectric constants, can be measured much better than with previous radar sensors. But even with foam, turbulent product surfaces, dirt and condensate, the Vegapuls 64 measures reliably thanks to the higher measurement reliability. The accuracy is ± 2 mm, even with a measuring range of 30 m.

The new radar level sensor Vegapuls 64 is suitable for wide use in all branches of process automation. Due to the technical advantages of 80 GHz technology, the sensor offers reliable level and level measurement for a wide range of water and wastewater applications. Thanks to its small antenna - the diameter of the smallest version is not larger than a 1 euro piece - and the resulting small process connection, the sensor is an interesting alternative for structurally restricted conditions.
