PRODUCT DESCRIPTION
The TBS-YG5 is an advanced unattended solar radiation measurement instrument, designed to eliminate the need for manual maintenance commonly required by traditional systems—especially for direct and diffuse radiation measurements. It fully meets the requirements of automated measurement by integrating robotic control technology with radiation sensing systems.
The system combines optical sun tracking, rotational angle measurement, irradiance measurement, and automated tracking operation, ensuring high-precision solar tracking. It simultaneously measures five key solar parameters: global radiation, diffuse radiation, direct radiation, sunshine duration, and solar elevation angle.
The instrument features powerful communication capabilities, enabling measurement data to be remotely transmitted to designated servers. It is widely applicable in meteorology, solar energy, photovoltaics, agriculture, construction, and scientific research.
2. Working Principle
The TBS-YG5 is designed to measure solar radiation intensity at different directions and times, and is widely used in atmospheric monitoring and satellite calibration.
The system consists of an optical head, control unit, and dual-axis stepper motor system. The optical head includes two sight tubes:
- One for direct solar radiation measurement (without focusing lens)
- One for sky radiation measurement (with focusing lens)
A quadrant detector is also integrated for fine adjustment during automatic sun tracking. The control unit contains two microprocessors, responsible for data acquisition and motor control. The dual-axis system enables movement in azimuth and elevation, using time-based calculations for initial positioning and the quadrant detector for precise tracking. The instrument is composed of a base, mounting frame, lead screw, gearbox, motor, controller, radiation sensors, and power supply. It operates using a combination of solar trajectory calculation and optical tracking, with 2-axis automatic tracking and automatic adjustment of the solar declination angle, enabling real-time, all-weather sun tracking.
Multi-parameter monitoring (radiation, sunshine duration, solar angle, GPS data)
Fully automatic, unattended operation with 2-axis sun tracking
Durable all-weather design (waterproof, dustproof, lightning protection)
Automatic zero calibration to eliminate cumulative errors
High-precision tracking with GPS support (stable under cloud/low-light conditions)
Flexible signal output & communication (0–20 mV, RS485/Modbus compatible)
