High-frequency microwave pulses transmitted by the guided wave radar propagate along the detector component (wire cable or steel bar), and are reflected on the surface of the medium. Part of the dielectrics to be measured, part of the dielectrics to be measured. The time interval between the emission of the pulses and their arrival is proportional to the distance between the surface of the medium and the reference plan of the instrument. The instruments have a low consumption; it can be installed on metallic or non metallic tanks. Their use is not harmful to humans or environment.  Guided Wave Radar utilizes time domain reflectometry (TDR) to continuously measure the distance, level, and volume of powders or solids in bins, tanks, and silos. This sensor features hazardous location approvals, a very small upper dead zone, and assures highly accurate level measurement in low dielectric materials down to 1.3. It has 4 -20 mA making it compatible with your HMI or PLC
