Campbell EE181, Инструкция по эксплуатации, Страница: 17 / 32

Model EE181 Temperature and Relative Humidity Probe
9
The RAD10E radiation shield attaches to a crossarm, mast, or user-supplied
pipe with a 2.5 to 5.3 cm (1.0 to 2.1 in) outer diameter. See FIGURE 7-2 for an
example of shield mounting.
The optimal location for the EE181 sensor tip inside a multi-plate shield is
approximately 1/3 to 1/2 of the way down from the top shield plate. With a ten-
plate shield, the tip of the EE181 should be located around three to four plates
down from the top of the shield. See FIGURE 7-1 .
