Product Profile

The 120GHzFMCW Radar level transmitterusing 10GHzsweep bandwidth, it is been calculated by FPGA chip hardwarecanachieve the Fast FourierTransform. The company’s engineer & technical personnel creatively applied diffraction wave separation and spectrum refinement algorithm techniqueto reach the measurement accuracy up to 0.217mm (Theoretical value) within 50 meters range, and in the static air vertical reflection surface test, the distance-resolution is 8mm.

The product DCRD1000B just need 80ms to finished the distance measurement & calculation process for 100m ranges. This allows the system to have more time and resources to deal with various kinds of things on level application of the instrument, such as: echo signal probability assessment / level prediction / level reliability analysis / input&output/ communication, etc.

DCRD1000Busing PTFE lens antenna with hermetic potting design,there is aperfect solution which resolved the antenna near field radiation suppression issues, that makes it has a good directional performanceand less 1 degrees beam angle (the mass product manufacturing process differences, may be biased ±0.3 degrees).


Application Features

120GHzFMCW radar level transmitter, especially be used inthe high temperature & pressure, strong dust& multiple mixing environment, itcan satisfymanyapplicationsfor a large range measurement with high-precision requirements.

The product DCRD1000Bhas an electromagnetic characteristic of the terahertz band, which makes it have advantage thatother radar level productshaven’t, such as its ability to penetrate non-polar materials( ray properties), in an industrial environment where strong adhesion and strong dust, it has ideal measurement stability and environmental resistance to dry torsion, and does not require any purge equipment. This product also has a very small antenna beam angle and strong self-adaptive automatic gain function, it don’t need to use the aiming configurationin most cases. Thisproduct’s applicationinstallation conditions are simple and economical, debugging is also efficient.



The main advantages:

1. Not be affected by atmospheric precipitation;

2. The ambient temperature is -60°C;

3. Being Installed on the outside of tank;

4. The antenna inside of the level transmitter is protected by fluoroplastic lens heating;

5. The measuring radiation is narrow, easy to install and measurement sensibility;

6. The accuracy of the level measurement can't be limited by the temperature of tank;

7. Evaporation and dust will not affect the measurement;

8. Boiling liquid level measurement;

9. Corrosive liquid level measurement, non-contact, non-corrosion, stable measure
