Radar level sensor CPR6800

Radar level meter is a wireless wave ranging system based on the principle of time travel. By transmitting a low-power microwave (radio wave with a frequency of 26GHz) pulse of less than 1mW through an antenna, this pulse propagates in space at the speed of light. The microwave pulse signal encounters the surface of the tested medium, and some of its energy is reflected back by the surface of the medium and received by the antenna. The time interval between the transmission and reception of microwave pulse signals is directly proportional to the distance from the antenna to the surface of the tested medium, and thus the distance from the antenna to the surface of the tested medium can be calculated.
