可以装进运输包里
概览
CM375是一种便携式的9.1米长的设备固定杆，可以用于安装传感器、机箱、太阳能板及天线。传感器通过横臂（例如CM202、CM204或CM206）连接到CM375主桅杆上。CM375的组装快速便捷，两个人可以在短短几分钟内就将CM375组装并竖立起来。为了安全稳固，在12英尺和24英尺高度都斜拉钢丝绳，再用地锚和钢丝绳坚固锁调节合适的坚固张力。

技术说明
CM375由5节1.8米长镀锌管、一个不锈钢基座、斜拉钢丝绳、一根一米长横臂及固定托架所组成。需要配置地锚。标准重载地锚套件作为通用附件（见订货信息）提供。
CM375含有一个2米长的运输包，所有的部件都可以装入运输包中，方便运输。
产品规格
| Material | Galvanized pipes |
| Guy Configuration | Three guy cables at two levels. Guyed at 3.6 m (12 ft) and at 7.2 m (24 ft). |
| Recommended Guy Wire Pretension |
45.4 kg (100 lb) each Check and adjust guy wire tension at least once a month, and after wind gusts exceeding 80 km/h (50 mph). |
| Wind Gust |
136 km/h (85 mph) The wind gust value assumes: (1) proper installation; (2) adequate soil for guy anchors/base support; (3) guy anchors at 6.1 m [20 ft] from base with 120° of separation; (4) guy tension of 45.4 kg [100 lb] each; (5) no ice buildup; and (6) standard air quality or wind assessment configuration [see table in manual]. The amount of wind gust that this mount can withstand is affected by quality of anchoring and installation, guy wire tension, soil type, guy angle, and the number, type, and location of instruments fastened to the CM375. |
| Base Radius | 6 m (20 ft) to each of three guy points; 120 degrees apart |
| Length | 10 m (32.8 ft) total for mast |
| Weight | 30 kg (66 lb) |
| Mounted Equipment Maximum Weight | 34 kg (75 lb) |
Mast |
|
| Sections | 5 |
| Main Mast Diameter | 48.26 mm (1.9 in.) |
| Top Section Mast Diameter | 44.2 mm (1.74 in.) |

Guy Duckbill Anchor Kits
Two duckbill anchor kits are offered as common accessories. (See the Ordering information.) The 19282 Guy Duckbill Standard Anchor Kit is adequate for most loamy soils. Clay soils and other soils with higher corrosive properties will require the 25699 Guy Duckbill Heavy Duty Anchor Kit. These corrosive soils, also known as aggressive soils, have one or more of the following properties:
- High electrical conductivity (>0.33 dS m-1)
- High acidity (pH < 5)
- High chloride concentration (> 1000 ppm)
- High sulfate concentration (> 500 ppm)
- Poor aeration
Contact Campbell Scientific if your site has the type of sandy soils found near the coastline.
常见问题解答
CM375: 7

-
The CM375 can endure extreme temperatures, such as almost 400°F on the high end.
-
The actual load on the mast can be approximately 34 kg (75 lb). If there is a lot of ice on the guy cables, they would need to be re-tightened more frequently. Campbell Scientific recommends checking the guy cables at least twice during an ice season. The guy cables should be positioned a little more vertically so that the ice doesn't pull them down so hard.
-
While there are no guarantees, as environmental conditions are unique from location to location, we expect that the mast of the CM375 would endure for 20 to 25 years in most coastal regions. In non-corrosive environments, we estimate the mast would endure for 50+ years. Having said that, because most of the parts are galvanized steel or stainless steel, they will corrode over time and eventually need to be replaced.
-
Consider using climbing anchors, such as those sold by sporting goods stores.
-
The mast has a lightning rod.
-
A stake kit, such as pn 16773, could be used to stake the base plate down. For very rocky areas, consider using concrete anchors.
-
No. The CM375 requires an anchor kit, and there are several options to choose from and order. Both standard and heavy-duty anchor kits are available, as well as a guy cable tensioning kit. These options are listed in the Common Accessories section of the Ordering information area on the CM375 product page.
