VEGA Radar Level Sensors

The radar level sensor continuously transmits radar signals from its antenna. The transmitted signals are reflected back after hitting the measured material. The frequency difference between the sent and received signals provides the measurement height. The result is then converted into a signal and displayed on the screen in the desired unit of measurement.

Sensors developed based on 80 GHz are highly suitable for areas such as the water and wastewater industry. These sensors have a high-precision focusing capability, ensuring reliable measurement values without being affected by environmental conditions like temperature fluctuations or contamination.

There are two types of models available: external and fixed cable connection (IP68). VEGAPULS radar level sensors operate at a frequency of 80 GHz. With an antenna length of 80 mm, this means the beam angle is only 3°. The radar sensor only measures the echo from the measured material, ensuring the measurement is highly secure and provides reliable results.

For a standard radar sensor with a transmission frequency of 26 GHz, the beam angle is approximately 10° on an antenna of the same size. Mixing equipment, other signal-disrupting devices, or adhesions on the tank walls, combined with a broader signal beam, negatively affect measurement results.
