Featuring compact size, easier mounting, and lower cost, the 43502 Aspirated Radiation Shield from R.M. Young has replaced the previous Model 43408 aspirated shield.

The 43502 uses a continuous-duty brushless blower that pulls ambient air into the shield and across the temperature sensor. This reduces measurement errors caused by solar radiation during the day, and errors caused by outgoing radiation at night.

The new shield is typically used with the 43347 RTD probe, but accommodates temperature and humidity sensors up to 0.9 inch in diameter. The mounting bracket and U-bolt attach the shield to a vertical or horizontal pipe up to 2 inches in diameter.
