076B Fan Aspirated Radiation Shield
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.
Features
- Errors reduced to < 0.05°F (< 0.03°C)
- Easy maintenance and sensor calibration
- Accommodate several sensors for Delta T measurements
- Radiation errors independent of outside emissivity
- Low-conductive interconnects
- DC or AC power operation
- Corrosion-resistant construction with white gloss epoxy enamel finish
- Easy mounting and tower servicing
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
