概览
CS120能见度传感器使用 尝试-测试 的红外前向散射技术，并采用已验证的 42° 散射角来报告雾/雪等天气下的气象学可观测距离（MOR），量程为 10 到 30,000 m。CS120既有高技术规格参数，又有非常有竞争力的价格，可单独使用也可与自动气象站相组合用于道路、海事、航空和风能环境等应用中。
优势与特点
- 高性能的传感器，有竞争力的价格
- 包含自动防露罩式加热器，用于所有天气条件下的操作
- 使用可选的校准套件，进行简单的野外校准
- 低功耗 - 适合远程应用
- 故障或窗口问题的自动状态检查
- 传感器设计最小化对测量体积的气流扰乱

技术说明
相对很多其它的能见度传感器来说，CS120的设计意味着能见度在一个相对干净的空间中测量，因为传感器头部和躯干的位置最小化了对测量体积中气流的干扰。
CS120使用连接的高速采样，改善了在雨/冰雹等混合天气下的测量精度；在浓雾或薄雾等稳定天气事件下也提供可靠的读数。高速采样还让CS120能对突然的条件变化有更好的响应。
CS120的几个设计特征让其光路保持清洁。向下朝向的光学镜头最小化了灰尘和雪的累积；低功率加热阻止了露水的生成；更高功率的加热能阻止冰的生成。
传感器非常节电，包括防露加热器在内的正常操作期间，功率只有3 W；功耗可以进一步减小，包括减小采样频率和手动控制加热器。
