ES-S228TAB 산란방사선 송신기

ES-S228TB scattered radiation transmitter consists of two parts: the solar total radiation transmitter and the scattered shading ring. The solar total radiation transmitter adopts the thermoelectric principle and used to measure solar radiation in the spectral range of 0.3~3μm. The sensing element adopts a winding electroplated thermopile, and the sensing surface is a black coating with high absorption rate. The thermal effect of radiation is used to absorb solar radiation and convert it into a thermoelectric potential. Auto temperature compensation ensure measure solar radiation more accurately. A double-layer glass cover is used above the sensing surface, which can not only reduce the impact of air convection on the equipment, but also block the radiation of the outer cover itself.

The function of the scattered shading ring is to ensure that the direct radiation of the sun can be continuously blocked from sunrise to sunset. The shading ring consists of a shading ring, a ruler, a screw adjustment screw, a bracket, and a chassis. The ruler is engraved with latitude and declination scales, and the corresponding parameters can be adjusted through the screw handle. The ruler and the bracket are fixed on the chassis and fixed for measurement according to the geographical latitude of the mounting location.
