The Aspirated Shield protects user-supplied sensor(s) from direct and
reflected solar radiation (insolation) as well as from wind-driven rain.
In addition to the shield itself, it includes: Temperature / Humidity
sensors. |

Passive Ventilation |

Five shield plates shade the outer wall of the aspirated tube. These
plates are made of a specially-formulated plastic proven to provide
superior performance in Davis Instruments’ passive radiation shield. They
reflect thermal radiation, have low thermal conductivity, and permit
natural air flow to reach the tube’s outer surface. Their unique design
permits vertical convection currents within the plate stack, preventing
the trapping of warm air between the plates. |
