Whether viscous, aqueous, coarse-grained 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.

Occasionally, though, exact measurement can be extraordinarily difficult. An example of this is when the measured media have a low dielectric constant (DK). Up until now, it was generally understood that a radar or microwave measurement would only function reliably in an obstacle-free tank when the medium had a dielectric constant of 2 or higher.

However, the 80 GHz VEGAPULS 64 and 69 Radar sensors – courtesy of their unique, high 120 dB dynamics – can detect and measure bulk solids and liquids which have a significantly lower dielectric constant reliably.

This is great news for the following widely used media, among others:

  • Polystyrene foam (otherwise called Styropor®): DK value 1.03
  • Plastic powder: DK value from 1.2
  • Palm oil: DK value 1.8
  • Glass fiber powder: DK value 1.1
  • Flax meal, bran, chaff: DK values from 1.3 to 1.5
  • Lime and gypsum: DK values 1.5 and 1.8
  • Coffee and cocoa beans: DK values 1.5 and 1.8
  • Wood chips: DK value 1.1

A further advantage of this is that it is no longer a requirement to search through long DK value lists. This is all courtesy of the VEGAPULS 80-GHz Radar sensors with 120 dB.
