3.4 Tripods, Towers, Enclosures, and Power
Supplies
There are several methods of mounting and housing sensors and other
equipment for a station.
3.4.1 Tripods and Towers for Mounting
For the different mounting requirements, Campbell Scientific offers the CM6
Tripod, CM10 Tripod, UT10 Tower, and UT30 Tower. All mounting options
available from Campbell Scientific are rugged instrument mounts that provide
sturdy support for Campbell Scientific sensors, enclosures, and measurement
electronics. The CM6 and CM10 Tripods can be used as a portable instrument
mount in a variety of applications. The UT10 and UT30 Towers provide a
more sturdy long-term support.
3.4.2 Enclosures
Enclosures are needed to keep water and debris from damaging the data
acquisition equipment. Campbell Scientific, Inc. enclosures are designated as
“rain-tight,” and are designed to mount to a tripod or tower. Following is a
description of the standard enclosures.
3.4.2.1 CR10X and CR23X Enclosures
Campbell Scientific offers two enclosures for housing a CR10X or CR23X and
peripherals. The fiberglass enclosures are classified as NEMA 4X (water-tight,
dust-tight, corrosion-resistant, indoor and outdoor use). A 1.25” diameter
entry/exit port is located at the bottom of the enclosure for routing cables and
