技术说明
CM120作为便携仪器安装设备有多种应用。在气象应用领域，可将多种传感器安装在三脚塔上，例如风向传感器、太阳辐射传感器、温湿度传感器。气压计、土壤温度/水分传感器，雨量计也可安装在以三脚塔为基础的气象站；对于非气象应用，也可将机箱和天线安装在三脚塔上。
CM120包括抗紫外绑扎带，接地套件和6个钢钎。
提供两种金属底垫套件用于固定斜拉线（请参看订购信息)。如果不使用这个配件，线缆会松动，脱离三脚塔。它能够帮助固定，从而使三脚塔可安装在风级较高的地方。
2007年三月开始Campbell供应不锈钢材质的CM120，在此之前所采用的材质为铝。

Additional Compatibility Information
Enclosures
The ENC16/18 cannot be mounted to the CM120's leg base, as the enclosure is too large for the space.
Enclosure Brackets
The “-MM” mount option for our environmental enclosures is intended for mounting the enclosure to a tripod's mast. An enclosure ordered with this option will be shipped with a three-piece bracket mounted to the top of the enclosure and an identical three-piece bracket mounted to the bottom of the enclosure.
The "-LM" mount option for our environmental enclosures allows the enclosure to be attached to the leg base of the CM120. This option includes a metal flange, two brackets, and a 2.5" u-bolt. The brackets attach to the right and left side of the enclosure, and the flange attaches to the tripod near the mast. The flange fits into a notch in one of the brackets, and the other bracket connects to a tripod leg via the u-bolt.

Installation time varies and depends on the instrumentation to be attached to the mast, as well as how the guy wires are anchored (for example, to the feet or using Duckbill anchors). On level ground with the guy wires attached to the feet, the installation time is approximately 60 minutes. Campbell Scientific recommends the assistance of one person at the base of the mast and two additional people to help raise the mast with the guy wires.
