Sensor shelter with artificial ventilation
Ventilated weather and radiation protection for universal use of sensors for measuring relative humidity and air temperature. The ventilation system draws in air from the surrounding area, which is passed directly past the sensor. This prevents measurement errors caused by direct and reflected radiation, especially in calm conditions.
- Artificial ventilation of the sensors
- No return of the heated air to the ventilation circuit
- Light transmission and radiant transmittance virtually eliminated
- UV and weather-resistant material
- Extremely robust with improved slat system
- Universally applicable for different sensors
- Easy installation including mounting material for various masts
