CS215是使用瑞士制造的元件,加工成的温度和相对湿度传感器。测量结果精确而稳定。元件基于Sensirion公司的CMOSens技术开发而来,在阿尔卑斯山脉条件下经过了2年多的测试。CS215采用SDI-12信号输出方式,可由大多数Campbell Scientific数据采集器来测量。
CS215采用Sensirion SHT75型组合式相对湿度和温度元件,来提供精确而稳定的测量。Sensirion SHT75元件可在野外更换,消除了由重校准产生的下线时间。CS215输出SDI-12信号,可由大多数Campbell Scientific数据采集器来测量。
CS215应该被固定在防辐射罩内,通常为41303-5A。41303-5A 6页防辐射罩为自然通风方式,可固定在主桅杆、横臂或直立塔的立柱上。

When exposed to sunlight, the CS215 must be housed in a 41303-5A radiation shield. To attach the 41303-5A to a CM202, CM204, or CM206 crossarm, place the 41303-5A’s U-bolt in the bottom holes. To attach the radiation shield directly to a tripod mast, tower mast, or tower leg, place the U-bolt in the side holes.
The CS215-L Temperature and RH sensor can also be housed in the 43502 if a special adapter from R. M. Young (R. M. Young pn 43537) is used.
