Product Description
Wavelength is 11.5mm. The wavelength of 6.8GHz radar is 47.6mm. When radar measures bulk material level (powder material), radar wave reflection mainly comes from diffuse reflection on the material surface. The intensity of diffuse reflection is proportional to the particle size of the material and inversely proportional to the wavelength, and the diameter of most bulk materials (powder materials) is far less than 47.6mm; high frequency, short antenna,
