Radar Level Sensor

Pokcenser provides full range of high accuracy radar level sensor which apply Frequency Modulated Continuous Wave (FMCW), which has a higher operating frequency and a shorter wavelength, particularly suitable for not only liquid but also solid applications. Despite 80GHz technology for unbeatable level accuracy, they can conquer the most harsh conditions like high temperature up to 300℃, pressurized tanks, powder and dust environment silos, corrosive chemical solvents, long measuring range of 120 meters, etc. IP67/IP68 protection grade, and narrowest 3°antenna beam angle, makes it less impact from interference in the installation environment. No matter radar level sensor for liquids, or radar level sensor for solids, we get one for you!
