荷兰 Kipp & Zonen SP Lite2 日射强度传感器产品介绍
中文介绍
SP Lite2 日射强度传感器是由荷兰 Kipp & Zonen 公司专为太阳辐射的常规测量而研发的新型设备。它继承了 Kipp & Zonen 数十年来的优秀品质，同时具备响应迅速、体积小巧、价格合理和维护方便等优点。该传感器适用于各种气象条件，能够测量来自整个半球范围内的太阳能量，广泛应用于光伏太阳能产品监测、农作物蒸散量评估、空气污染扩散计算以及日常教学等领域。
SP Lite2 采用硅光电二极管传感器，能够提供电压输出信号。其独特的扩散器设计使得灵敏度与入射光线入射角的余弦成线性变化，从而确保测量数据的准确性和一致性。此外，该传感器的外形设计使其在有降水的气象条件下不易形成积水，且易于清洁。内置水平泡的设计方便用户在安装时进行调平操作，以确保测量数据的准确性和可靠性。两个 SP Lite2 还可以采用“背靠背”的方式安装在一起，形成一个简单的反照率测量仪。产品标配 5 米电缆，用户也可以根据实际需要选配 15 米的电缆线。
SP Lite2 的主要技术参数包括：光谱范围 400~1100nm，灵敏度 60~100μV/W/m²，响应时间（95%）小于 500ns，最大辐射 2000W/m²，非稳定性（年变化）小于 2%，非线性（0~1000W/m²）小于 1%，定向响应小于 10W/m²（<80°，1000W/m²），温度依赖性为 -0.15%/℃（-30℃~70℃），工作温度范围为 -30℃~70℃，典型信号输出为 0~100mV，阻抗为 50Ω，视角为 180°。
English Introduction
The SP Lite2 Pyranometer is a new type of solar radiation measuring device developed by Kipp & Zonen in the Netherlands for routine solar radiation measurement. It inherits the excellent quality of Kipp & Zonen over the past decades and features fast response, compact size, reasonable price, and easy maintenance. The sensor can be used in all weather conditions to measure solar energy from the entire hemisphere and is widely used in photovoltaic solar product monitoring, crop evapotranspiration assessment, air pollution dispersion calculation, and daily teaching.
The SP Lite2 uses a silicon photodiode sensor that provides voltage output signals. Its unique diffuser design ensures that the sensitivity varies linearly with the cosine of the angle of incidence of incoming radiation, guaranteeing the accuracy and consistency of measurement data. Additionally, the sensor s design prevents water accumulation and is easy to clean during rainy weather. The built-in bubble level facilitates leveling operations during installation to ensure accurate and reliable measurement data. Two SP Lite2 sensors can be installed back-to-back to form a simple albedometer. The product comes with a standard 5-meter cable, and users can also choose a 15-meter cable according to their needs.
The main technical parameters of the SP Lite2 include a spectral range of 400–1100 nm, sensitivity of 60–100μV/W/m², response time (95%) of less than 500ns, maximum irradiance of 2000W/m², non-stability (annual change) of less than 2%, non-linearity (0–1000W/m²) of less than 1%, directional response of less than 10W/m² (<80°, 1000W/m²), temperature dependence of -0.15%/℃ (-30℃ to 70℃), operating temperature range of -30℃ to 70℃, typical signal output of 0–100mV, impedance of 50Ω, and a viewing angle of 180°.
