The new net pyranometer is used to measure the net difference between the downward projection of the sky and the upward projection of the full-band radiance from the earth's surface. The measurement range is short-wave radiation from 0.3 to 3 microns and earth radiation from 3 to 50 microns. It is mainly used to study the state of the earth's heat budget, and can be applied to meteorological research, thermal stress and heat balance research, and highway road condition monitoring.
The working principle of the watch is the thermoelectric effect. The sensing part is a thermopile composed of constantan wire with copper plating. The top of the thermopile is coated with 3M matte black paint. Two thermopiles receive solar radiation and earth radiation respectively. Due to the difference in radiation intensity absorbed by the upper and lower sensing surfaces, a temperature difference occurs at both ends of the thermopile, and its output electromotive force is proportional to the difference in radiation intensity received by the sensing surface.
In order to prevent the influence of wind and rain on the output of the pyranometer and protect the sensing surface, the meter is equipped with a hemispherical special polyethylene film that can pass through both short-wave radiation (0.3-3 microns) and long-wave radiation (3-100 microns). cover.
