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°, the outstanding performance makes it workable for the accurate measurement of liquids, solids and powder materials.It is widely adopted in industries such as cement, chemicals, mining, petroleum, and water treatment.
Why Choose Our Radar Level Gauge?
Precision Engineering Backed by Industrial Experience
With over 15 years of field application experience, YUHAN has been at the forefront of non-contact radar level measurement. The YHDAR-8x series is the culmination of extensive R&D and field feedback, engineered to deliver reliable results even in complex process environments such as:
· High-dust environments (cement silos, fly ash tanks)
· Aggressive chemicals (acid or alkali liquids)
· High temperature or pressure tanks
Working Principle of 80G FMCW Radar Level Gauge
The Frequency-Modulated Continuous Wave (FMCW) radar transmits signals within the 76–81GHz band. The returning echo from the material surface is mixed with the transmitted signal. Using advanced FFT analysis, the difference in frequency is converted to precise distance measurement — unaffected by temperature, pressure, vapor, or dust.
Key Advantages:
Higher resolution & stability vs. 26GHz radar
Smaller blind zone: Only 8cm
Narrow beam angle: ~3°, allowing accurate targeting in narrow vessels
FMCW Technology: Better performance in challenging measurement conditions
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°beam angle and shorter wavelength, the interference on the influence of the instrument are smaller. Bluetooth wireless debugging is optional.
