TBQ total radiation sensor adopts the principle of thermoelectric induction, which is used with various radiation recorders or radiation ammeters, and can accurately measure the sun?s total radiation, reflected radiation, scattered radiation, infrared radiation, visible light, ultraviolet radiation, long wave radiation, etc.

The core induction element of the table adopts the winding electroplating type multi-contact thermoelectric reactor, and its surface is coated with a black coating with high absorption rate. The hot contact is on the induction surface, while the cold junction is located in the body, and the cold and hot junction produces the temperature difference potential. In the linear range, the output signal is directly proportional to the solar irradiance.

The double glass cover is designed to reduce the effect of air convection on the radiation surface, and the inner cover is designed to truncate the infrared radiation of the cover itself.
