KH.GDF Photoelectric Global Radiation Sensor | Total Solar Radiation Monitoring for Agriculture Environmental Protection Meteorology and Energy
Product Introduction
The KH.GDF Photoelectric Global Radiation Sensor uses a high-sensitivity photoelectric detector to measure total short-wave radiation under sunlight. The measured radiation data can be output via RS485 communication. The sensor features an all-solid-state design with robust structure, high reliability, and is suitable for long-term, continuous monitoring in harsh outdoor environments.
Key Features
• Integrated design : Compact, elegant, and easy to install.
• High reliability : Maintenance-free with stable long-term operation.
• Advanced sensing technology : Real-time measurement with high accuracy and strong anti-interference capability.
• All-weather durability : Solid structure with high strength, corrosion resistance, and waterproof performance.
• Low power consumption : Efficient operation for continuous monitoring.
• Flexible communication : RS485 output for easy integration with telemetry systems.
Application Scenarios
• Agricultural solar radiation monitoring
• Environmental protection and ecological research
• Meteorological observation stations
• Energy, transportation, and construction projects requiring light monitoring
