TBQ-2C total radiation sensor:
TBQ-2C type total radiation sensor is developed, designed and produced by Yunnong Wisdom Company. A first-order meter used to measure the total solar radiation with the wavelength of 0.3-3.2 micrometers. the sensing element is the core part of the meter, which is composed of a fast response wire-wound electroplated thermopile. The induction surface is coated with 3M matte black paint is a hot contact. When there is sunlight, the temperature rises, and it forms a thermoelectromotive force with the cold contact on the other side, which is proportional to the solar radiation intensity.
