Kacise OEM Radar Level Gauge 10m 80G RS485 Radar Level Transmitter For Septic Tank 10m Level measurement transmitter 80G RS485 radar level gauge for non-corrosive liquide KLD801 80G radar level gauge adopts frequency modulated continuous wave (FMCW) technology. The antenna emits a high-frequency FM radar signal, and the frequency of the radar signal increases linearly. The transmitted radar signal is received by the same antenna after being reflected by the measured medium. At the same time, the frequency difference between the transmitted signal frequency and the received signal frequency is proportional to the measured distance. The collected frequency difference signal is subjected to fast Fourier transform (FFT) to obtain the spectrum of the reflected echo, and the distance to the target to be measured is calculated based on this. Working Principle The radar antenna transmites narrow microwave pulse which will be reflected back when reaching the surface of the medium tested and then received again by the antenna system. The signals shall be transmitted to the electric circuit and then converted into level signals. As the transmission speed of microwave is so fast, the time used for the microwave transmission to the surface of the medium tested and then reflected back is almost 0. Technical Features ⚫ Millimeter wave radar, the measurement accuracy can reach up to ±2mm, and the minimum measurement blind zone is 0.05m. ⚫ The smaller antenna size satisfies the measurement of more working conditions.
