80Ghz High Frequency Pulse Radar Level Transmitter

80Ghz High Frequency Pulse Radar Level Transmitter

The 80ghz High Frequency Pulse Radar Level Transmitter is FMCW radar operating at 76-81 GHz. It has a maximum measuring range of 120m and a minimum blind zone of 8cm.

It supports 4-wire and 2-wire applications. Higher operating frequency and shorter wavelength make it ideal for solid applications, including those with extreme dust and high temperature to + 200℃.

The radar consists of an electronic circuit coupled to a lens antenna and flange for quick and easy positioning.

Feature:

1. Based on the self-developed CMOS millimeter wave RF chip, a more compact RF architecture, a higher signal-to-noise ratio, and a smaller blind zone are realized.

2. 5GHz working bandwidth means higher measurement resolution and accuracy.

3. 3° antenna beam angle, so the interference in the environment has less impact on the instrument, and the installation is more convenient.

4. Shorter wavelength yields good reflection properties on sloped solids, so aiming towards material angle of repose is usually not necessary.

5. Support remote debugging and remote upgrading to reduce the cost of field personnel.

6. Non-contact radar, wear-resistant and no pollution.

7. A variety of output circuit interfaces and acquisition system.

8. The integrated anti-corrosion cover structure effectively prevents the corrosive medium from coming into contact with the probe and has excellent anti-corrosion performance.

Typical applications of intelligent radar object level meter:

1. Power plant: coal pile, raw coal bunker, fuel bunker, reservoir, waste gas purification tank, bin pump, ash storage, fuel tank, etc.

2. Oil field: crude oil or product oil storage tank, three-phase separator, settling tank, sewage tank and oil-water interface, drilling mud tank, etc.

3. Chemical engineering: crude distillation tower, raw material and intermediate bunker, reaction tank, ammonia tank, solid bunker, separator, etc.

4. Metallurgical: ore bin, ore crusher, raw material warehouse, auxiliary materials warehouse, blast furnace, alumina powder warehouse, electrolytic tank buffer tank, etc.

5. Mud: stone warehouse, raw material warehouse, cement warehouse, pulverized coal warehouse, slag storage warehouse, etc.

6. Water treatment: reservoir, sewage tank, water treatment tank, sedimentation tank, deep well, drinking water network, etc.

7. Paper making: raw material warehouse, storage tower, drying drum, chemical material storage warehouse, etc.

8. Others: quarry, food, pharmaceutical, environmental protection, shipbuilding and other industries.
