Description

scattering radiation transmitter is composed of solar total radiation transmitter and scattering light shielding ring. The total solar radiation transmitter adopts the thermoelectric principle and can be used to measure the spectral range of 0.3~3 μ M solar radiation. The sensing element adopts wire wound electroplated thermopile, and the sensing surface is a black coating with high absorption. The thermal effect of radiation is used to absorb solar radiation and convert it into thermoelectric electromotive force. With temperature compensation function, it can accurately measure the solar radiation. The double-layer glass cover is used above the sensing surface, which can not only weaken the impact of air convection on the equipment, but also block the radiation of the housing itself. The function of the scattering shading ring is to ensure that the direct solar radiation can be continuously blocked from sunrise to sunset. The light shielding ring is composed of a light shielding ring, a ruler, a screw adjusting screw, a bracket and a chassis. The ruler is engraved with latitude scale and declination scale, and the corresponding parameters can be adjusted through the lead screw handle. The ruler and bracket are fixed on the chassis and measured according to the geographic latitude of the launching site
