Overview
YURA 2301 FM Radar level transmitter is a 120GHz FM radar type level measuring instrument with a measuring distance of up to 30 meters. The antenna is further optimized for processing and the new fast microprocessor allows for higher speed signal analysis and processing, making the instrument available for measurement of high temperature and high pressure and other environmental liquids
Product Principle
The general principle of frequency modulated continuous wave radar level meter is that the radar emits electromagnetic waves at the top of the tank, and the electromagnetic waves are received by the radar after hitting the medium and reflected. Because the speed of light C and FM slope K are known, so the frequency difference δ f is estimated, and the distance R of the material surface at the radar installation position can be obtained, and then the height of the material level is obtained by subtracting the spatial distance from the radar to the material surface (referred to as the empty height) from the known total height of the tank.
Protection Grade
This instrument fully meets the requirements of protection class IP66/67. Please make sure that the cable sealing head is waterproof. As shown How to ensure that the installation meets the requirements of IP67. Please make sure that the sealing head is not damaged. Please make sure that the cable is not damaged. Please ensure that the cable used meets the requirements of the electrical connection specification. Before entering the electrical connection, bend the cable downwards to ensure that water does not flow into the housing, see ① Please tighten the cable sealing head, see ② Please plug the unused electrical connections with blind plugs, see

Installation Requirements
When installing the instrument, avoid installing it above the inlet, and try to avoid all kinds of objects that affect the signal, such as stirring paddles, etc.
Under extremely complicated working conditions, the instrument can work normally if there is no obstacle in the area of 500px radius with the radar installation point as the
