Wintersense SDI-12是一款远程路面温度传感器,设计用于道路天气信息系统(RWIS)。它是一种易于部署、无创、紧凑、重量轻的传感器,可以安装在现有的路边结构上,如路灯柱或RWIS塔。Wintersense SDI-12具有电缆连接,用于与RWIS站或数据采集器进行电力和通信,用于数据存储和转发。
通过准确、实时的路面温度数据,您可以预测冬季道路护理情况,防止交通事故和潜在的生命损失。
Wintersense SDI-12配备了一个热电堆传感器,可检测目标表面是否存在热辐射。该传感器还具有一个集成的光学滤波器,可切断可见光和近红外辐射通量,消除环境和阳光的干扰。这些功能与八秒信号平均算法相结合,为您提供了这些测量参数的最佳数据:
