BGT-TBQ total radiation sensor uses pyroelectric sensor principle,
used in conjunction with various radiation the total solar
radiation, the reflected radiation, scattered radiation, infrared
radiation, visible light, ultraviolet radiation, long wave
radiation.
Core inductive element of the sensor, using winding plating
multi-contact thermopile, its surface is coated with the black
coating of the high absorption rate. The hot junction is located in
the body, hot and cold contacts to generate thermoelectric power.
Within the linear range, in proportion to the output signal and
solar irradiance.
The double glass is in order to reduce the impact of the air
convection radiation table, the inner cover is set in order to cut
off the infrared radiation of the nacelle itself.
