Whether viscous, coarse-grained, aqueous or powdery: A wide variety of liquids and bulk solids ensure reliable supplies of raw materials for production – provided that the operators know the exact filling levels. Sometimes, however, exact measurement is extremely difficult. For example, when the measured media have a low dielectric constant (DK). Until recently, the 'rule' was that a microwave or radar measurement in an obstacle-free tank only functioned reliably when the medium had a dielectric constant of at least 2.
So I would like to know what is the dynamic range of the new radars.
Alan1, give me a few and I will get a complete answer for you. In a nutshell, low dynamic range means it's difficult to discern between level reading and background noise. High dynamic range means easier to tell level signals from background noise. 80 GHz shows a higher dynamic range because it concentrates the energy and gets a nice clear reception and a nice clear "blip" showing level. Thanks, Jeff
The dynamic range of our 80 GHz radar is 140 dB. We don't publish this in the literature - we prefer to use the Amplitude measurement that you see when using the DTM. Please see the attached photo.
Think of dynamic range in terms of music (a lot of musicians and recording equipment refer to dynamic range). The high dynamic range gives a radar the ability to "hear" weak signals. And "hear" through the background noise.
