Overview

The CM375 is a corrosion-resistant 10 m (30 ft) mast for applications requiring a tall yet portable instrument mount. It can support sensors, an environmental enclosure, a solar panel, and an antenna. Sensors are attached to the CM375 mast via mounts such as the CM202, CM204, and CM206 crossarms. To reinforce the mount, the CM375 is guyed at 3.7 m (12 ft) and 7.3 m (24 ft) heights. Duck-bill anchors and
the guy-wire tensioning kit ensure proper guying.

Detailed Description

The CM375 comes with five 2 m (6.56 ft) galvanized pipes, a stainless-steel base, guy cables, a 1 m (3.3 ft) crossarm, and a mounting bracket. An anchor kit is required; standard and heavy-duty anchor kits are offered as Common Accessories (see Ordering Info). A guy tensioning kit is also available as a Common Accessory.

A 2 m (80 in) bag is included with the CM375; all of the CM375's components fit inside the bag, allowing the CM375 to be carried from site to site.

Guy Duckbill Anchor Kits

Two duckbill anchor kits are offered as common accessories (see Ordering Information). The 19282 Guy Duckbill Standard Anchor Kit is adequate for most sandy and 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

Specifications

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
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.)
Section Length 2 m (6.56 ft)
Total Length 10 m (32.8 ft)
