Hukseflux DR02 一級直接輻射表
產(chǎn)品概述
Hukseflux DR02是一款研究級直接太陽輻射傳感器，也稱為太陽熱量計，專為高精度太陽輻射測量設(shè)計。該傳感器采用獨特的熱電堆技術(shù)，可快速響應太陽輻射變化，并配備窗口加熱功能，有效消除鏡頭結(jié)露對測量精度的影響。DR02需要配合雙軸太陽跟蹤器使用，特別適合太陽能研究和光伏應用領(lǐng)域。12
產(chǎn)品特點
DR02具有快速響應特性，95%響應時間僅需1秒，能夠準確捕捉瞬態(tài)太陽輻射變化。其低功率窗口加熱器（0.5W@12VDC）通過循環(huán)開啟/關(guān)閉模式，在日出前自動消除鏡面結(jié)露現(xiàn)象，顯著提升清晨時段的測量準確性。傳感器的熱隔離設(shè)計和精密光學系統(tǒng)確保了長期穩(wěn)定的測量性能。產(chǎn)品出廠前均經(jīng)過嚴格校準，靈敏度達到10μV/W/m²。26
技術(shù)參數(shù)
該產(chǎn)品視角為5°，溫度依賴性為0.1%/℃，標準配備5米電纜并可延長。工作環(huán)境適應性強，可部署于各類氣候條件下。測量時需連接具備10mV測量能力的數(shù)據(jù)采集設(shè)備，配合全自動太陽跟蹤器平臺使用。其緊湊結(jié)構(gòu)和輕量化設(shè)計便于安裝維護，廣泛應用于氣象觀測、太陽能資源評估等領(lǐng)域。217
Product Introduction
The Hukseflux DR02 is a research-grade pyrheliometer designed for direct solar radiation measurement. As a high-performance solar energy sensor, it features rapid response characteristics and integrated window heating technology. The instrument requires mounting on a sun tracker for accurate normal incidence irradiance (DNI) measurement, making it particularly suitable for solar energy research and photovoltaic system monitoring applications.911
Key Features
This sensor stands out with its 1-second response time (95%) and unique thermal isolation design. The low-power window heater (0.5W@12VDC) operates in cyclic mode to prevent dew formation before sunrise, ensuring reliable dawn measurements. Its precision optical system with 5° opening angle delivers consistent performance under varying environmental conditions. Each unit is individually calibrated with sensitivity of 10μV/W/m².1416
Technical Specifications
The DR02 pyrheliometer demonstrates minimal temperature dependence (0.1%/℃) and comes standard with 5m cable (extendable). When combined with automatic sun tracker and data acquisition system (minimum 10mV resolution), it provides accurate DNI data for solar resource assessment, meteorological observation, and renewable energy research. Its robust construction and maintenance-friendly design support long-term outdoor deployment.1720
