product description

80GHz frequency modulated continuous wave radar object/level gauge series products adopt 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 moment, 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 frequency spectrum of the reflected echo, and the distance of the target to be measured is calculated from this.

The advantages of 80Ghz FMCW radar level meter

DDCRD1000B only needs 80ms to complete a complete measurement and calculation process for a distance of 100m. This allows the system to have more time and resources to deal with various things in the meter level application, such as: probability,evaluation/prediction/credibility ,analysis/input/output/communication, etc.


Ⅱ、Application characteristics

The 80GHz frequency modulation radar level gauge is especially suitable for high temperature, high pressure or high dust, and multiple mixing spaces. It meets many measurement requirements that require a large range and high precision.


The working frequency of DCRD1000B product has electromagnetic characteristics in the terahertz band, which makes it have characteristics that other measurement radar products do not have. For example, it has the ability to penetrate non-polar materials (like ray properties), and it has strong adhesion In the dusty industrial environment, it has ideal measurement stability and environmental resistance to interference, and does not require any blowing device. This product also has a very small antenna beam angle and a strong adaptive automatic gain function, in most cases it does not need to use the sight configuration. This makes the installation requirements of this product in the field very simple and economical, and the commissioning is also fast.

Ⅲ、Main advantage

Compared with 26G or 6G radar, 80G radar has higher frequency, shorter wavelength, smaller beam angle and more energy concentrated characteristics; coupled with the application of FMCW technology, it has the following characteristics:

1.Large range, small blind area;

2.The beam angle is small, the antenna size is small, and it is easy to install. Less affected by tank connection size and obstacles;

3.The measurement accuracy is high, the anti-interference ability is strong, and the reliability is high.

    Case application I The anti-corrosion radar level meter DCRD1000A5&DCRD1000C5 was successfully applied to a chemical project in Inner Mongolia Since Acid-base solutions are extremely corrosive in industrial production measurement applications, the wetted materials of equipment must be anti-corrosion materials. Our high-frequency radar level meter DCRD1000A5 and guided wave radar level gauge DCRD1000C5 are special models for corrosive conditions. Radar antennas are made of PTFE with good anti-corrosion performance, which has good sealing performance, strong corrosion resistance and stable measurement results.Any inquiry about the radar level meter, welcome to contact us at any time.

    The  Features of DCRD1000C series of Guided Wave Radar Level meter (GWR)The guided wave radar level meter is an excellent level meter with advanced technology, excellent workmanship and high precision. When the guided wave radar level meter is working, an electromagnetic pulse signal is emitted, which is transmitted to the liquid level and returned at a constant speed through a probe or a steel cable, thereby simply and accurately calculating the liquid level height.Guided wave radar level meter are currently used in a wide variety of tank containers. It is used to measure the liquid level or level of medium such as aqueous medium, acidic medium, alkaline medium, oil medium, and particles.The guided wave radar level meter (DCRD1000C series) independently developed by Xi'an Dechuan...

    Air purge+Nuzzle ,  Universal joint:The necessary adjunct when measuring the level of bulk solid in silos bins and tanks.When radar level meter measure the level of solid medium, such as grains, cement powders, solid particles,  the solid material  will form a stockpile or hopper in the silo when feeding  or undloading. Then the antenna of the radar level meter need to perpendicularly alignment to the medium surface,  if the material is uneven,  and the heap angle is large then the universal joint flange is needed to adjust the horn angle to aim the charge level.(Due to the inclination of the solid surface it will cause the problem of  echo decay or even the signal loss.)When measuring the bulk solids, there will bring very heavy dust.  we add an air...
