技术说明

这个版本的HMP45C，线缆配有军品规格的快速接头，并具有用户指定的长度。探头的快速接头连接到RAWS-P 机箱，后者可固定在CM6/CM10 三脚塔、CM110系列三脚塔或UT系列直立塔上。探头使用HUMICAP电容型薄膜多聚物传感器来测量相对湿度，和一个PRT传感器来测量温度。 相对湿度的量程是0 到 100% RH，温度的量程是 -40° 到 +60°C。

兼容性

The sensor cable terminates in a military style connector and a user-specified lead length. The connector attaches to the RAWS-P enclosure.

Mounting

The HMP45C-LQ should be housed in a 41003-5 10-plate naturally-aspirated solar radiation shield. This radiation shield mounts to a tripod or tower mast, crossarm, or user-supplied pole.
