The solar radiation sensor operates on the photoelectric principle to measure solar radiation in the range of 0.3~3μm. It features a high-precision photosensitive element with wide-spectrum absorption, high absorption efficiency, and excellent stability. A dust cover with up to 95% light transmittance is installed over the sensing element. The cover undergoes special treatment to reduce dust accumulation and effectively prevents environmental interference, enabling more accurate measurement of solar radiation. The product supports standard Modbus-RTU communication protocol, allowing direct reading of real-time solar radiation values with ease. Compact and sleek design requires minimal installation space. Suitable for applications in solar energy utilization, meteorology, agriculture, building material aging studies, and air pollution monitoring. High-precision sensor with strong full-spectrum absorption capability. Includes leveling base and adjustment handwheel for convenient on-site calibration. Features a highly transparent dust cover with superior light sensitivity and special surface treatment to minimize dust adhesion.
