80g FMCW RADAR LEVEL TRANSMITTER
  

INTRODUCTION


YHDAR-8x series radar level sensor is one kind of level measuring instrument which uses FMCW special millimeter wave technology, the working frequency is 76-81GHz. The signal output has options: 2-wire 4-20mA, 4-wire 4-20mA or RS485. The max measuring range can reach 120m, and the blind zone of 8cm. The antenna beam angle is about 3¡ã, the outstanding performance makes it workable for the accurate measurement of liquids, solids and powder materials.


WORKING PRINCIPLE


YHDAR-8x series launch a microwave signal frequency changing with the time linearly,the reflected signal and the launched signal are mixed through the "mixer". The difference of frequency is proportional to the distance from radar to the reflection surface and get the distance information required through the FFT transform.


FEATURE


YHDAR-8x is based on the complementary metal-oxide-semiconductor transistor (CMOS) and 5GHz working bandwidth, and it has a higher signal-to-noise ratio and smaller blind zone, higher measurement resolution and accuracy. With 3¡ãbeam angle and shorter wavelength, the interference on the influence of the instrument are smaller. Bluetooth wireless debugging is optional.
