Radar/liquid level gauge, non-contact liquid level or solid measurement; Type fully sealed antenna: anti condensation, crystallization, hanging material, dust; Small beam angle and concentrated energy; The antenna size is small, making it easy to install and install antenna protective devices such as dust covers; The measurement blind spot is smaller, and it can also achieve good results for measuring small cans; Shorter wavelength makes it more suitable for level measurement of small particulate matter.
Characteristics of 80G FM radar level gauge:
1. Millimeter wave radar with a measurement accuracy of ± 2mm, capable of measuringZThe small blind spot is 0.05m。
2. The smaller antenna size meets the measurement needs of more working conditions.
3. Multiple lens antennas, smaller emission angles, more concentrated energy, stronger echo signals, and higher reliability compared to other radar products under the same mining conditions.
4. It has stronger penetrability and can be used normally even in the presence of adhesion and condensation.
5. The dynamic signal range is larger, making it more stable for measuring low dielectric constant media.
6. Multiple measurement modes, with a radar response time of less than 1 second in fast measurement mode.
main advantages
1. Not affected by atmospheric precipitation;
2. The ambient temperature starts at -60 degrees Celsius;
3. Install from outside the storage tank;
4. The antenna inside the level gauge is heated and protected by a fluoroplastic lens;
5. Narrow measurement radiation, easy installation, and stable measurement;
6. The accuracy of level measurement is not limited by the temperature inside the container;
7. Evaporation and dust will not affect the measurement;
8.Boiling liquid level measurement;
9. Corrosive liquid level measurement, non-contact, non corrosive - stable measurement;
