380-43502 Motor Aspirated Radiation Shield

The 380-43502 Aspirated Radiation Shield provides maximum sensor protection from incoming short wave solar radiation and outgoing long wave radiation. The shield employs a triple walled intake tube and multiple canopy shades to isolate the sensor from precipitation and solar radiation. A continuous duty blower draws ambient air through the intake tubes and across the sensor, minimizing radiation errors. Compact shield components reduce radiation absorption and improve aspiration efficiency. Specially selected plastic materials provide high reflectivity, low conductivity, and maximum weatherability. The versatile DC blower is designed for cntinuous duty of more than 80,000 hours (9 years) at 77°F (25°C). Brushless electronic commutation is achieved using dependable solid state circuitry.
