1. Frequency and Beam Angle
• 26 GHz Radar:
• Lower frequency results in a wider beam angle (typically 8°-10°).
• Suitable for wider tanks or applications with fewer obstructions.
• Better for long-range measurements (up to ~30-40 meters).
• 80 GHz Radar:
• Higher frequency creates a narrower beam angle (typically 3°-4°).
• Ideal for narrow tanks or applications with obstructions, as the narrow beam avoids interference.
• Provides higher accuracy and resolution, particularly at shorter ranges.
2. Application Environment
• 26 GHz Radar:
• Works well in standard applications with minimal interference.
• Performs adequately with liquids and solids but may struggle with small or complex tank structures.
• 80 GHz Radar:
• Excels in challenging environments, such as tanks with agitators, baffles, or deposits.
• Handles low dielectric constant materials (e.g., hydrocarbons) more effectively.
• Performs better with solids, powders, or granules due to higher resolution.
3. Measurement Range
• 26 GHz Radar:
• Typically supports longer measurement ranges (e.g., up to 40 meters for liquids).
• A good choice for large tanks or open reservoirs.
• 80 GHz Radar:
• Suitable for medium to long ranges (e.g., up to 30 meters).
• Ideal for high-precision applications or smaller tanks.
4. Installation and Mounting
• 26 GHz Radar:
• Requires larger antennas due to the wider beam angle, which might limit installation in confined spaces.
• Easier to install in open tanks or vessels.
• 80 GHz Radar:
• Compact and smaller antennas make installation easier in tight spaces.
• Suitable for vessels with small process connections.
5. Cost
• 26 GHz Radar:
• Generally less expensive, making it cost-effective for standard applications.
• 80 GHz Radar:
• Higher cost due to advanced technology, but worth it for complex or high-accuracy applications.
When to Choose Each
Choose 26 GHz Radar If:
• The application involves large tanks or reservoirs.
• There are fewer obstructions in the tank.
• You need a cost-effective solution for standard measurements.
Choose 80 GHz Radar If:
• The tank or vessel has narrow spaces, obstructions, or complex structures.
• High accuracy and precision are critical.
• The material has a low dielectric constant or is in solid/granular form.
• You need to avoid interference in challenging environments.
Ultimately, the choice depends on your application’s requirements, environmental conditions, and budget. For the most challenging or high-precision tasks, 80 GHz radar is typically superior.
