KLD803 80G FM Radar Level Sensor
Introduction
Effect Of Radar Level Transmitter Frequency Range On Measurement
The radar level gauge emits electromagnetic waves through the antenna. The higher the frequency of the electromagnetic wave, the higher the energy of the electromagnetic wave. The shorter the wavelength, the more obvious the scattering phenomenon. Conversely, the lower the energy, the longer the wavelength, and the energy is not easily absorbed by the gas phase layer.
For the same size antenna, a liquid level sensor with a wavelength of 1.2 cm and a frequency of 26 GHZ has a gain of 6 times higher than that of a liquid level sensor with a wavelength of 3 cm and a frequency of 10 GHZ. (Remarks: Antenna gain is a parameter indicating the degree of radiation concentration of a directional antenna).
The overall beamwidth of a radar level gauge is inversely proportional to the frequency of the device. Therefore, for the same diameter antenna, if the frequency of the radar level gauge is increased, the beam width will be lower than that of the lower frequency equipment, and the narrow beam can minimize the influence of the nozzle, tank wall and interference.
At the same time, the measurement range of the radar level gauge is also affected by factors such as frequency, antenna size, dielectric constant of the liquid, and process conditions.
