Description:

Thermoelectric Total Radiation Sensor measures the total solar radiation in the spectral range of 0.3-3μm based on the thermoelectric effect. It can also be used to measure oblique radiation, reflected radiation, and scattered radiation. The sensing element adopts a wire-wound electroplated thermopile. The cold and hot junctions generate a temperature difference potential, which is converted into radiation flux density. Integrated temperature and nonlinear compensation functions. Double-layer quartz glass windshield, the inner cover has an infrared band isolation function, and the transmittance is as high as 0.95 or more.

Note 1: Add a shading ring to measure scattered radiation;

Note 2: The sensing face is downward to measure reflected radiation
