Visibility & Present Weather Sensors
The state of the art in fog detection for Road Weather Information Systems (RWIS), Airport Weather Observation Systems (AWOS) and Coast Navigation Systems. The product family of Lufft visibility sensors providing highly accurate results with minimum maintenance and absolute reliability.
OTT Parsivel² - Laser Weather Sensor
Laser precipitation disdrometer measuring all precipitation types
The OTT Parsivel² is a modern laser disdrometer for comprehensive measurement of all precipitation types. The Parsivel² captures both the size and speed of falling particles, classifying them into one of 32 separate size and velocity classes.
- Precipitation type, intensity, drop size distribution, radar reflectivity
- Laser (optical)
- Simultaneous measurement of 32 classes for particle sizes and velocities
- SDI-12 / RS-485, pulse
Visibility Sensor VS2k-UMB
New product version of the known Lufft VS20 visibility sensor with a measurement range of 10...2000m, easy calibration functionality, sea waterproof housing and (active) spider defence
The VS2k visibility sensor measures visibility up to 2000m, ideal for road traffic applications on motorways, highways or bridges. Long life time is guaranteed thanks to the sea-water proof housing design.
