PYR20 pyranometer, or solar radiation sensor, measures global solar irradiance including both direct and diffuse components. Internal temperature compensation minimizes errors due to sensor heating. Each sensor 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 Equipped with temperature compensation and level indicator Spring-loaded design for easy installation IP66 rated for outdoor use High accuracy, excellent stability, and reliable performance Reverse power protection and built-in TVS/ESD protection Technical 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: 3 screw holes - Color: Black - Material: Plastic - Output type: 4-20 mA Package includes: 1 x Sensor Note: Other items not included.
