Product Description
The APT90 series sensors are 76-81GHz continuous frequency modulated radar level measuring instruments. The radar emits electromagnetic waves from the antenna, which will reflect when encountering the interface between two materials with different dielectric constants. The echo is detected by a receiver, and the transmission time is used to calculate the material level; the reflected radar wave is digitally converted into an echo graph, and the distance from the medium surface to the instrument reference point is determined by analyzing the echo graph. The interval is proportional to the distance from the antenna to the surface of the measured medium.
