總輻射傳感器BL-ZFS
產(chǎn)品概述
BL-ZFS總輻射傳感器是一款基于熱電效應(yīng)原理設(shè)計(jì)的高精度太陽輻射測量設(shè)備，主要用于測量光譜范圍為0.28-3μm的太陽總輻射。該產(chǎn)品采用繞線電鍍式多接點(diǎn)熱電堆作為核心感應(yīng)元件，表面涂覆高吸收率黑色涂層，通過冷熱接點(diǎn)產(chǎn)生的溫差電勢實(shí)現(xiàn)輻射能量與電信號的線性轉(zhuǎn)換。傳感器配備精密光學(xué)冷加工磨制的石英玻璃罩，有效減少環(huán)境溫度及外界因素對測量精度的影響。16
技術(shù)特點(diǎn)
該傳感器具有優(yōu)異的穩(wěn)定性和線性響應(yīng)特性，靈敏度范圍為7~14μV/W·m⁻²，響應(yīng)時(shí)間≤30秒（99%），在-20℃至+40℃工作環(huán)境下溫度特性誤差控制在±2%以內(nèi)。雙層石英玻璃罩設(shè)計(jì)進(jìn)一步降低了空氣對流干擾，內(nèi)罩可有效阻隔外罩紅外輻射。產(chǎn)品支持0~20mV模擬信號輸出，配合變送器可轉(zhuǎn)換為4~20mA標(biāo)準(zhǔn)電流信號，適用于各類數(shù)據(jù)采集系統(tǒng)。余弦響應(yīng)偏差在太陽高度角10°時(shí)不超過±5%，年變化率穩(wěn)定在±2%以內(nèi)。146
應(yīng)用領(lǐng)域
BL-ZFS廣泛應(yīng)用于太陽能資源評估、氣象觀測、農(nóng)業(yè)生態(tài)研究、建筑材料老化測試及環(huán)境監(jiān)測等領(lǐng)域。通過調(diào)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(yīng)面向下）及散射輻射（加裝遮光環(huán)）。其緊湊結(jié)構(gòu)設(shè)計(jì)（重量約1.5kg）便于野外安裝，標(biāo)配防護(hù)罩能適應(yīng)多種氣候條件，為可再生能源開發(fā)、氣候研究和環(huán)境分析提供可靠數(shù)據(jù)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
