‌1. Overview

It is mainly used in various tanks, pools, warehouses and other storage bodies, and rivers, ditches and other indoor and outdoor occasions, to measure the height, distance and level of powders, solids, liquids, etc., and it can be used for collision avoidance and early warning of vehicle-mounted equipment. This product adopts FMCW (continuous frequency modulation wave) radar level sensing technology, transmits microwaves to the surface of the medium, and continuously modulates the frequency. At the same time, it receives FMCW continuously, and the frequency difference between transmission and reception is proportional to the distance to the material. The data can be transmitted to the upper computer or controller through the output signal to realize timely and accurate judgment of the height of the material and the distance of the vehicle equipment from the obstacle.
