Krohne Optiwave 7500 Radar Level Transmitter
Manufacturer: Krohne Inc
Mfg Product Code:
The OPTIWAVE 7500 is a 2-wire 80 GHz radar (FMCW) level transmitter for demanding liquid applications involving narrow tanks with long nozzles and internal obstructions like agitators or heating coils. Its very small beam angle and negligible dead zone make this FMCW radar the optimal choice for continuous, non-contact level measurement in both extremely small and very high tanks (up to 100 m / 328 ft). The level transmitter is even able to measure through tank roofs made of non-conductive materials. Its PEEK and PTFE Lens antennas are insensitive to deposits and well suited for corrosive environments. As the antennas are flush-mounted, there is no intrusion into the tank.
80GHz Radar (FMCW) Level Transmitter for liquids in narrow tanks with internal obstructions
- Large measuring range from the antenna up to 100m/ 328ft
- Small beam angle due to 80GHz and process connections starting from ¾¨ thread
- PEEK Lens antenna insensitive to deposits
