概览

CS215-PWS为带有特殊接头的温度和相对湿度传感器，可连接到PWS100机箱。  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。CS215-PWS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。

优势与特点

  • Accurate and stable measurements
  • Field changeable element allows on-site recalibration
  • Each sensor element is individually calibrated so no further adjustment of the probe is required
  • Low power consumption
  • Digital SDI-12 output
  • Simple data logger programming

技术说明

该版本的CS215温湿度探头，线缆不是尾线方式，而是连接到PWS100机箱的快速接头；线缆长度为 1米。

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，可心大多数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。
