🔬 80 GHz Technology Breakthrough
The Micropilot FMR62B radar level transmitter operates at 80 GHz W-band frequency, delivering significant advantages over conventional 26 GHz radar transmitters:
| Feature | FMR62B (80 GHz) | Conventional (26 GHz) |
|---|---|---|
| Beam Angle | 3° | 8° typical |
| Minimum Measuring Distance | 0.3 m (12 in) | 1 m+ (39 in) |
| Resolution | 1 mm (0.04 in) | 3 mm+ (0.12 in) |
| Interference Suppression | Excellent (narrow beam) | Moderate |
| Nozzle Compatibility | DN50 / 2″ and larger | DN80 / 3″ and larger |
The narrow 3° beam angle eliminates interference from tank walls, internal structures, and agitators, making the FMR62B radar level transmitter ideal for complex tank geometries.
