HCDAR-8X series radar level sensor is one kind of level measuring instrument which uses FMCW ( Frequency Modulated Continuous Wave ) special millimeter wave technology , the working frequency is 76-81Ghz. The signal output has options : 2 wires 4-20mA, 4 wires 4-20mA or RS485.  The max range can reach 120m, and the blind zone of 8cm. The antenna beam angle is about 3°,the outstanding performance makes it is workable for the accurate measurement of liquids, solids, and powder materials. 

Advantages

• Based on the complementary metal-oxide-semiconductor transistor (CMOS) components with high compact architecture, gives higher signal to noise ratio and smaller blind zone. 
• 5GHz working bandwidth means higher measurement resolution and accuracy. 
• 3°antenna beam angle, so the interference in the environment has less impact on the instrument and the installation is more convenient. 
• Shorter wavelength offers better reflection performance on solid surface, so the universal flange is not necessary. 
• Supporting remote debugging and upgrading, reduce waiting time and improve the working efficiency.
