Precipitation Sensor R2S-UMB - discontinued
The radar precipitation sensor Lufft R2S-UMB allows fast measurement of precipitation intensity and distinguishs between precipitation type (Rain, snow, sleet, freezing rain, hail). The operation is maintenance-free, thanks to radar measurement technology
The speed rate of drops is registered with a 24 GHz doppler radar system. By comparison between the speed rate and the size of drops, the quantity of rain or its intensity will be registered. The road condition (rain/snow/snow-covered rain/freezing rain/hail) is determined thanks to the speed rate of the rain. Resolution up to 0.01mm, without maintenance.

- Very fast response time - Rain detection with the first drop! Very important for traffic applications, where every minute counts!
- Distinguishs different precipitation types (Rain, snow, sleet, freezing rain, hail)
- Maintenance-free operation – no moving parts that can wear out thanks to radar measurement technology
- Suitable for solar-powered automatic meteorological stations
- Resolution for rain intensity of 0.01 mm
The maintenance-free and extremely fast measurement of precipitation type and intensity fits perfect the needs of the following applications...
Examples of Use:
- Weather observation for road and traffic control systems (RWIS - road weather information station)
- Weather stations at airports
- Weather stations of meteorological services
- Mountain weather stations for avalanche and flood warning
- Hydro-meteorological stations
