總輻射傳感器BL-ZFS
產品概述
BL-ZFS總輻射傳感器是一款基于熱電效應原理設計的高精度太陽輻射測量設備，主要用于測量光譜范圍為0.28-3μm的太陽總輻射。該產品采用繞線電鍍式多接點熱電堆作為核心感應元件，表面涂覆高吸收率黑色涂層，通過冷熱接點產生的溫差電勢實現輻射能量與電信號的線性轉換。傳感器配備精密光學冷加工磨制的石英玻璃罩，有效減少環境溫度及外界因素對測量精度的影響。16
技術特點
該傳感器具有優異的穩定性和線性響應特性，靈敏度范圍為7~14μV/W·m⁻²，響應時間≤30秒（99%），在-20℃至+40℃工作環境下溫度特性誤差控制在±2%以內。雙層石英玻璃罩設計進一步降低了空氣對流干擾，內罩可有效阻隔外罩紅外輻射。產品支持0~20mV模擬信號輸出，配合變送器可轉換為4~20mA標準電流信號，適用于各類數據采集系統。余弦響應偏差在太陽高度角10°時不超過±5%，年變化率穩定在±2%以內。146
應用領域
BL-ZFS廣泛應用于太陽能資源評估、氣象觀測、農業生態研究、建筑材料老化測試及環境監測等領域。通過調整安裝方向，可靈活測量水平面總輻射、斜面入射輻射、反射輻射（感應面向下）及散射輻射（加裝遮光環）。其緊湊結構設計（重量約1.5kg）便于野外安裝，標配防護罩能適應多種氣候條件，為可再生能源開發、氣候研究和環境分析提供可靠數據支持。138
Product Overview
The BL-ZFS Pyranometer is a high-precision solar radiation measuring device based on thermoelectric principle, designed for measuring total solar radiation within 0.28-3μm spectral range. Its sensing element features a wire-wound electroplated thermopile with high-absorption black coating, converting radiative energy into electrical signals through temperature gradient between hot junctions (on sensing surface) and cold junctions (inside housing). The precision-ground quartz glass dome provides effective protection against environmental interference. 16
Technical Features
This sensor demonstrates outstanding stability with linear output, offering 7~14μV/W·m⁻² sensitivity and ≤30s response time (99%). Temperature compensation ensures ±2% accuracy across -20℃ to +40℃ range. The dual-layer quartz dome minimizes air convection effects while inner dome blocks infrared interference. Standard 0~20mV analog output can be converted to 4~20mA via transmitter. Cosine response deviation remains within ±5% at 10° solar elevation angle, with annual stability of ±2%. 4626
Applications
Widely adopted in solar energy assessment, meteorological observation, agricultural research and environmental monitoring, the BL-ZFS supports versatile measurements including global horizontal irradiance, tilted surface radiation (via angular mounting), reflected radiation (downward-facing) and diffuse radiation (with shading ring). Its rugged construction (1.5kg weight) and weather-resistant design facilitate field deployment, delivering reliable data for renewable energy projects, climate studies and material durability analysis. 3813
