Guided-Wave-Radar Level Sensors

May 27, 2008
Unlike other devices, Flexar guided-wave-radar level sensors, based on time domain reflectometry, measure the level of challenging powders because TDR is not affected by dust. The sensors are reliable, accurate, and easy to install and commission. A continuous series of radar pulses is emitted and guided to the material surface by the heavy-duty stainless-steel cable probe. When the radar pulses reach the material surface, they are reflected because of the change in dielectric constant. The radar pulses’ time of flight is measured and directly related to the distance measured.
