Description
The 076B Fan Aspirated Radiation Shield protects temperature and humidity sensors from direct and indirect radiant energy. Used in the most adverse conditions, the 076B eliminates errors caused by solar or terrestrial radiation, as well as secondary errors caused by convective heat transfer from the outer shield surfaces. It continuoulsy samples ambient air to support high accuracy temperature and differential temperature measurements. It is the best aspirated shield available on the market. A humidity sensor can be installed in the shield for combined measurements.

Construction
  • The shield is constructed of aluminum and other corrosion-resistant materials
  • All outer surfaces are painted with high-gloss epoxy enamel for maximum reflectivity
  • All interconnecting materials minimize conductive heat transfer

Operation
Air is drawn into the bottom of the sensor housing through two concentric ports. The air sample moves at high velocity through the outer port and scrubs the outer surfaces as it is exhausted. The inner port then draws in the sample, enabling a true gas temperature measurement to be made.
