Compact Radar Level Measurement Excellence

The NRE-7 compact radar level transmitter represents the latest advancement in industrial measurement technology, utilizing state-of-the-art 80 GHz FMCW radar. This innovative device offers significant advantages over lower-frequency alternatives, featuring a compact antenna design and superior focusing capabilities. The most fundamental benefit of 80 GHz technology compared to lower frequencies (5...12 GHz and 25 GHz) is its ability to deliver precise measurements through a smaller antenna size, enhanced focusability, and narrow beam angle.

This technology excels in measuring liquids, masses, emulsions, and chemicals across diverse industries, providing millimeter-accurate measurements even in challenging conditions. Its advanced design handles substances prone to vapor formation and liquids with gas blankets effectively, while also performing reliably with large-particle bulk solids. Beyond basic level measurement, the NRE-7 offers sophisticated volume and weight measurement capabilities, along with integrated open-channel flow measurement functions. The device's threshold management system effectively eliminates false and interfering echoes, ensuring reliable measurements in complex tank environments.

Operating on FMCW technology, the NRE-7 maintains exceptional accuracy regardless of temperature and medium pressure variations. Since millimeter waves don't require a medium for propagation, the device performs equally well in vacuum conditions, making it versatile for various industrial applications.
