  • Wind Speed / Wind Direction

The Wind Speed/ Wind Direction Sensor determines the speed and direction of wind.




  • Relative Humidity / Air Temperature

The Relative Humidity / Air Temperature sensor determines air temperature and the level of humidity relative to the ambient temperature.



  • Precipitation Occurrence

The Precipitation Occurrence sensor provides a (Yes/No) signal to indicate if precipitation, in any form, is occurring or not.



  • Precipitation Identifier/Classifier

The Precipitation Identifier/Classifier detects the occurrence of precipitation, identifies the precipitation type (rain, snow, drizzle), and measures precipitation rate and short range visibility.




  • Visibility

-Monitors visibility over a range of 0 to 10 miles (0 to 16 km).
-Adjusts for natural variations in background light intensity.

Barometric Pressure
Permanent calibration ensures that the Barometric Pressure Sensor does not require periodic service or maintenance.

Solar Radiation Sensor
Highly stable sensor measures diffused and direct sun radiation.

Designed for Harsh Environments
All SSI atmospheric instruments are designed for reliable operation in the harsh road / runway environment.
