Solar Total Radiation Sensor / TBQ
The solar total radiation sensor using thermoelectric induction principle, and a variety of radiation recorders or radiation ammeter with the use of precise measurement of the sun’s total radiation, reflected radiation, scattered radiation, infrared radiation, visible light, ultraviolet radiation, long-wave radiation.
The core of the table sensing element, the use of winding electroplating multi-junction thermopile, the surface coated with a high absorption rate of black coating. Thermal contact on the sensing surface, while the cold junction is located in the body, hot and cold junction temperature difference potential. In the linear range, the output signal is proportional to the solar irradiance.
Double glazing is to reduce the impact of air convection on the radiation meter, the inner cover is to cut off the cover itself infrared radiation and set up.
