NBL-W-HPRS/Total radiation sensor V3.0
Changsha Zoko-Link Technology Co., Ltd.
Product introduction
The TBQ total radiation sensor adopts the principle
of thermoelectric induction and is used in conjunction
with various radiation recorders or radiation
ammeters to accurately measure the sun's TBQ total
radiation, reflected radiation, scattered radiation,
infrared radiation, visible light, ultraviolet radiation,
long-wave radiation, etc.
The core sensing element of the watch adopts a
wire-wound electroplating multi-contact thermopile,
and its surface is coated with a black coating with
high absorption rate. The hot junction is on the
sensing surface, while the cold junction is located in
the body, and the cold and hot junctions generate a
thermoelectric potential. In the linear range, the
output signal is proportional to the solar irradiance.
The double-layer glass cover is to reduce the
influence of air convection on the pyranometer, and
the inner cover is designed to cut off the infrared
radiation of the outer cover itself.
Use
The meter is used to measure the total solar TBQ
radiation in the spectral range of 0.3-3μm, and it can
also be used to measure the solar radiation incident
on the inclined plane. If the sensing surface is facing
down, the reflected radiation can be measured, and
the shading ring can be used to measure the scattered
radiation. Therefore, it can be widely used in solar
energy utilization, meteorology, agriculture, aging of
building materials and air pollution to measure solar
radiation energy.
