Description
The ERT-A2120 One-Piece 60GHz Radar Level Transmitter is designed for stable and accurate non-contact liquid level measurement in industrial applications. Based on 60GHz FMCW radar technology, it provides high measurement precision with a narrow 9° beam angle, effectively reducing false echoes caused by tank structures, liquid turbulence, and environmental interference. The compact integrated design combines level display, control, and alarm functions, making it an efficient solution for automated liquid level management.
The transmitter supports optional relay outputs for high and low-level alarm control, enabling direct connection with pumps, valves, and other control equipment. Two antenna versions are available: the Lens Antenna Version for liquids with impurities, foam, or turbulence, and the Basic Antenna Version for clean, non-corrosive liquids without impurities.
With IP65 protection, durable materials, and flexible power supply options, the ERT-A2120 ensures long-term stable operation with low maintenance requirements, making it suitable for water treatment, industrial tanks, and various liquid level monitoring applications.
