80G Non-Contact Radar Level Sensor
WEpower 80GHz radar level sensor represents cutting-edge technology for non-contact liquid level measurement in industrial applications. Utilizing a high-frequency 80GHz FMCW (Frequency Modulated Continuous Wave) radar signal, it delivers millimeter-level accuracy even in challenging process conditions.
What Is The Principle Of Our 80G Non-Contact Radar Level Sensor?
The general principle of the FM continuous wave radar level gauge(80G non-contact radar level sensor) is that the radar emits electromagnetic waves on the top of the tank, and the electromagnetic waves are received by the radar after being reflected by the medium. The frequency difference δf between the received signal and the transmitted signal is proportional to the distance R from the surface of the medium: R=C (speed)*δf (frequency difference)/2/K (frequency modulation slope). Because the speed of light C and the frequency modulation slope K are known, the frequency difference δf can be estimated to obtain the distance R from the radar installation position to the material surface, and then through the known total height of the tank, subtract the spatial distance from the radar to the material surface (referred to as Empty height) to get the height of the material level.
