7.3.1 Shield Installation
It is recommended to use the EE181 with the MetSpec RAD10E multi-plate
radiation shield due to shield performance in bright sunlight and low wind
speeds as well as over snow or reflective surfaces. The EE181 will work with
the RM Young 10-plate shield but requires a special adapter (pn 28415) to
accommodate sensor girth.
7.3.1.1 Installation in a RAD10E 10-Plate Shield
Do not mount the shield or route the sensor cable into the
enclosure until after the EE181 is installed inside the shield.
1. Loosen the sensor gland nut on the bottom of the shield.
2. Insert sensor into the bottom of the multi-plate shield. Situate the gland so
it’s 1/2 inch to 1 inch above the sensor connector. See FIGURE 7-1 .
3. Tighten the nut around the gland until it firmly grips the body of the probe.
Use an adjustable wrench if necessary, but do not overtighten the nut.
7.3.1.2 Installation in an RM Young 41003-5 10-Plate Shield
Do not mount the shield or route the sensor cable into the
enclosure until after the EE181 is installed inside the shield.
1. Slide the adapter over the sensor body and situate the adapter so it’s 1/2
inch to 1 inch above the sensor connector.
2. Insert sensor and adapter into the bottom of the multi-plate shield.
3. Hold the collar and sensor and finish threading the collar into the shield by
hand. Tighten the collar around the probe until it firmly grips the body of
the probe. Use an adjustable wrench if necessary, but do not overtighten
the collar.
7.3.2 Mount the Shield
1. Attach the radiation shield to the tripod mast, crossarm, or tower leg using
the supplied U-bolt. See FIGURE 7-2 for an example of shield mounting.
2. Route the cable to the datalogger, and secure the cable to the mounting
structure using cable ties.
