PYR20 pyranometer, or solar radiation sensor, measures global solar irradiance including both direct and diffuse components. The sensor features internal temperature compensation to minimize errors caused by sensor heating. Each unit is calibrated against an Eppley Precision Spectral Pyranometer, ensuring high accuracy and consistency. Suitable for scientific research, solar power systems, greenhouses, weather stations, and other outdoor applications. Measurement range: 0-2000 W/m² Spectral range: 400-1100 nm Output options: RS485, voltage, or current Integrated temperature compensation Level indicator with spring-loaded leveling mechanism for easy installation Weatherproof rating: IP66, suitable for outdoor use High accuracy, excellent stability, and consistent performance Reverse power protection and built-in TVS/ESD protection Specifications: - Pyranometer Range: 0-2000 W/m² - Accuracy: ±5% - Resolution: 1 W/m² - Directional Error: ±3% (0°–70°), ±10% (70°–85°) - Operating Temperature: -40°C to +85°C - Installation: Three screw holes - Color: Black - Material: Plastic - Output Type: 4-20 mA Package Contents: 1 x Sensor Note: Other items not included.
