The fan aspirated radiation shield combines active and passive aspiration to minimize the effects of radiation.
Fan aspirated solar radiation shield.
Specifications for this item.
Cable is shielded twisted pair wire with a tpr jacket for high water resistance uv stability and flexibility in cold conditions.
The benefit is even more pronounced in rainy conditions.
Accuracy is not affected by shield contamination.
In fact for higher reliability and lower maintenance applications helical radiation shield wins.
We have multi plate radiation shield both naturally aspirated and fan aspirated solar radiation shield.
Half the cost of our 24 hour fan aspirated radiation shield but nearly 75 as effective in reducing the effects of daytime radiation.
Aspirated radiation shields feature an ip68 marine grade stainless steel cable connector located on the fan optional for temperature sensors to simplify sensor removal for maintenance and recalibration.
Solar powered fan runs during the day.
A solar powered fan operates during the day and then shuts down at night when the effects of radiation are less keeping the sensors cool and accurate.
Fan aspirated radiation shield installation instructions addendum for vantage pro2 and vantage pro2 plus the vantage pro2 integrated sensor suite iss with the fan aspirated radiation shield uses a combination of fan aspiration and shielding to minimize temperature measurement errors due to the effects of solar radiation.
Shields come in naturally ventilated or aspirated versions and fan aspirated versions.
Comparison was performed by an independent researcher in italy concluding that the davis fan aspirated radiation shield provided no benefit over the naturally aspirated helical meteoshield.
Solar radiation shields permit the measurement of air temperature in the presence of bright sun without allowing the sun to warm the thermometer which would give a falsely high measurement of air temperature.
