KQS-ZSYT Fully Automatic Direct-Diffuse Integrated Radiation Monitoring Instrument with High Accuracy Dual Tracking Global Applicability and Multiple Communication Options
The KQS-ZSYT fully automatic direct-diffuse integrated radiation monitoring instrument is a comprehensive, all-weather, unattended system designed for continuous measurement of direct solar radiation, diffuse radiation, and global (total) solar radiation.
The system adopts an advanced dual tracking mechanism: a four-quadrant optical tracking system and a GPS-based solar trajectory tracking system. The high-precision four-quadrant optical tracking automatically compensates for installation errors, significantly reducing installation requirements. The GPS solar trajectory algorithm enables accurate sun-position tracking under cloudy or overcast conditions.
The device can be equipped with various types of solar radiation sensors. It offers stable performance, strong payload capacity, and excellent environmental adaptability, allowing reliable operation under extreme climatic conditions. It is widely used in photovoltaic environmental monitoring, solar radiation observation, agricultural and forestry research, and related fields.
- Global applicability: Suitable for use worldwide between 60°S and 60°N latitude, unaffected by geographic location.
- High accuracy dual tracking system:
- Active tracking (four-quadrant optical tracking): accuracy < 0.1°
- Passive tracking (GPS solar trajectory calculation): accuracy < 0.5°
- Multiple communication options: Standard RS485 communication; optional 4G and Bluetooth communication for flexible deployment.
- Easy installation: Simple setup, no external transmitter required; radiation data is processed and directly readable by users.
- High reliability: All-weather operation with high stability, resistance to extreme temperatures, and no need for manual intervention.
