Professional Customized Supply High-quality OEM Total Solar Radiation Sensor Suppliers & Manufacturers-CHENYUN

YGC-TBQ total radiation sensor adopts the principle of thermoelectric induction and can be used in conjunction with various radiation recorders or radiation voltmeters to accurately measure the total radiation of the sun.
The core sensing element of the watch uses a wire-wound electroplated multi-contact thermopile, and its surface is coated with a high-absorption black coating. The hot junction is on the sensing surface, while the cold junction is located inside the body. The hot and cold junctions generate a temperature difference potential. In the linear range, the output signal is proportional to solar irradiance.
The double-layer glass cover is to reduce the impact of air convection on the pyranometer, and the inner cover is designed to cut off the infrared radiation of the outer cover itself.
This meter is used to measure total solar radiation with a spectral range of 0.3-3μm. It can also be used to measure solar radiation incident on a slope. If the sensing surface is downward, it can measure reflected radiation. If a light shielding ring is added, it can measure scattered radiation. Therefore, it can be widely used in solar energy utilization, meteorology, agriculture, building material aging, air pollution and other departments to measure solar radiation energy.
