Bulletin H-RHRSThe Series RHRS Radiation Shieldprotects outside air humidity transmitters fromrain and radiated heat. With the curved shape and color of the plates, air flow isable to move across the sensor to keep radiated temperatures from rooftops andsurrounding surfaces from affecting humidity readings. For ease of installation, theSeries RHRS has integral pipe mounting hardware which can be removed forsurface mounting applications. The brackets on the Series RHRS are specificallydesigned to be installed on the Dwyer Series RHP outside air humidity transmitterswith sintered filters.INSTALLATIONStep 1:Loosen plastic probe retainer on radiation shield by unscrewing two retainer screws.Step 2:Slide humidity transmitter probe completely into radiation shield.Step 3:Screw plastic probe retainer to the radiation shield until the probe is firmly held in place. Do not over tighten the screws.For Pipe MountingStep 4:Remove the u-bolt from the mounting bracket.Step 5:Secure the radiation shield to 3/4˝ to 1-1/2˝ iron pipe.For Surface MountingStep 4:Remove the u-bolt and the screw holding the pipe retaining bracket.Step 5:Mark the outer two holes of the mounting bracket on the surface.Step 6:Drill the two holes marked in the previous step into the surface.Step 7:Attach the radiation shield to the surface.DWYER INSTRUMENTS, INC.
