Radiation Shield ]

The Gill Aspirated Radiation Shield provides maximum sensor protection from incoming short wave solar radiation and outgoing long wave radiation.

The shield employs concentric downward facing intake tubes and a small canopy shade to isolate the sensor from direct and indirect radiation. A continuous duty blower draws ambient air through the intake tubes and across the sensor minimizing heat transfer to the sensor. 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 continuous duty of 80,000 hours at 25°C. Brushless electronic commutation is achieved using dependable solid state circuitry.

The Temperature Probe is a 1000 ohms Platinum RTD encased in a stainless steel protective sheath. The sensing element is secured in a convenient junction box that fits YOUNG radiation shields. The probe is available with various output options. The 4-20 mA current output is useful in high noise, industrial settings or for long cable lengths. The 0.1 VDC option provides a calibrated voltage output signal.

The Relative Humidity / Temperature Probe combines a high accuracy humidity sensor and a 1000 ohms Platinum RTD. Available with 0-1 VDC or 4-20 mA outputs, sensors are mounted in a common junction box.
