Vaisala Forward Scatter Sensor FD70 is a visibility and present weather sensor with:
- Visibility up to 100 km (62 mi)
- Precipitation type identification, intensity, and accumulation
Due to its innovative technology, FD70 reliably detects and identifies precipitation types that have been challenging for conventional technologies.
FD70 has multiple features to ensure reliable operation even in extreme weather conditions. Effective hood heating and proven look-down geometry protect the sensor windows against external disturbances. These are complemented with independent optical path monitoring and window contamination compensation.
Self-diagnostics and modular design enable short service times. Redundancy of data communication is available for critical cases such as airport use.
FD70 complies with ICAO, FAA, and WMO requirements and uses WMO and NWS weather codes in reporting.
