Unaffected by heavy steam, condensation, and vapors, the VEGAPULS Pulse Radar offers a range of models designed to meet the needs of the pulp and paper manufacturers. The sensor transmits energy in the form of microwave pulses. These pulses are directed toward a specific target that reflects the energy back to an antenna. The amount of energy that returns to the antenna depends on the reflective properties of the material being measured. Reflectivity can be determined by examining two characteristics, conductivity and dielectric constant (DK).

The transit time of the microwave pulse that returns to the antenna is measured and used to calculate the distance to the target. Conductive products, such as water and acids, have very good reflectivity and can be measured regardless of the DK value. For non-conductive materials, the DK value alone determines the reflectivity. Materials with a low DK absorb a large portion of the microwaves transmitted by the radar sensor, thus reducing the energy reflected back to the antenna.
