The ERT-A2120 is a one-piece high-frequency radar level transmitter based on 60 GHz FMCW radar technology, providing stable and accurate non-contact liquid level measurement. With a narrow 9° beam angle, the sensor effectively suppresses false echoes caused by tank structures, turbulence, or environmental interference, ensuring reliable level readings.
The device supports level display, control, and alarm functions in a single unit, making it an ideal solution for automated liquid level control systems. Optional relay outputs enable high-level and low-level alarm control, allowing direct linkage with pumps and valves.
Two antenna configurations are available:
Lens Antenna Version – Suitable for various media, including liquids with impurities or turbulence
Basic Antenna Version – Recommended for clean, non-corrosive, impurity-free liquids
With robust materials, IP65 protection, and wide power supply options, the ERT-A2120 delivers long-term stability and low maintenance in complex field conditions.
