ESMRD-800 80GHZNon-contact Radar level meters for 4-20ma /rs485 output
Working Principle
The 80G radar bit meter adopts frequency modulation continuous wave (FMCW) technology.The antenna emits high-frequency FM radar signals, 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 obtains the frequency spectrum of the reflected echo by the fast Fourier transform (FF T), and thus calculates the distance o of the target to be measured
Product Features
The product refers to a frequency modulated continuous wave (FMCW) radar product operating at 76-81GHz.The product range can reach 65m, and the blind zone is within 10 cm.Due to its higher operating frequency, larger bandwidth and higher measurement accuracy.The product provides the fixing method of the bracket, which makes the installation convenient and easy without on-site wiring.
1.Based on the self-developed CMOS millimeter-wave radio frequency chip, it realizes a more compact radio frequency structure, a higher signal-to-noise ratio, and a smaller dead zone.
2.5GHz working bandwidth, so that the product has higher measurement resolution and measurement accuracy.
3.The narrowest 6° antenna beam angle, the interference in the installation environment has less influence on the instrument, and the installation is more convenient.
4.Integrated lens design, compact size.
4.Low power consumption operation, lifespan is more than 3 years.
5.When the water level exceeds the upper and lower limits (configurable), upload alarm information.
