CEL-NP2000-Sun180 solar power meter Introduction: CEL-NP2000-Sun180 solar power meter is mainly used to measure the total solar radiation with the wavelength range of 300nm~3000nm outdoors, which can test the light power radiation value under the continuous all-weather angle of 0-180 ° solar light, and realize all-weather measurement. The solar power meter can measure the reflected radiation value from the sensing side down, and can also be used to measure the solar radiation incident on the inclined plane. The scattered radiation can be measured by adding a light-shielding ring. CEL-NP2000-Sun180 solar power meter can be widely used in outdoor weather, solar energy utilization, solar energy measurement, agricultural and forestry, building material aging, atmospheric environmental monitoring and other departments of solar radiation energy measurement. The solar power meter is composed of double-layer quartz glass cover, sensing element, sunshade, meter body, desiccant, etc. The double-layer glass cover is used to reduce the influence of air convection on the radiation meter. The inner cover is designed to cut off the infrared radiation of the outer cover itself. The sensing element is the core part of the solar power meter, which is composed of a fast response wire wound electroplated thermopile. The sensing surface is coated with special matt black paint and hot spots. When the sun is shining, the temperature rises and forms a thermoelectric electromotive force with the cold spots on the other side. The electromotive force is proportional to the solar radiation intensity to achieve real-time measurement. Technical parameters: 1. Sensitivity: 7~14 μ v•w-1•m-2 2. Spectral range: 300nm~3000nm 3. Measuring angle: 0-180 ° (omni-directional) 4. Test range: 0 ～ 2000W • m-2 5. Annual stability: ≤± 2% 6. Cosine response: ≤± 7% (when the solar altitude angle is 10 °) 7. Orientation: ≤± 2% (when the solar altitude angle is 10 °) 8. Response time: ＜ 10s (95% response) 9. Nonlinearity: not more than ± 2% 10. Temperature drift coefficient: not more than ± 2% (- 10~40 ℃) 11. Output signal; 0～20mV
