1. Introduction The UT6 and UT10 are durable, lightweight instrument towers used for a variety of applications. They support a 1.8 m (6 ft) or 3 m (10 ft) measurement height for wind sensors as well as sturdy attachment points for antennas, solar panels, environmental enclosures, radiation shields, and crossarms.
Inspect the shipping cartons for visible damage. Report any damage to the shipping company. Open all shipping cartons. Check the contents of the cartons against the invoice. Contact Campbell Scientific immediately if any parts are missing. 3.2 Outdoors Locate a suitable site for the tower (Siting and exposure (p.
Install the instrumentation enclosure (Tower installation (p. 9)). Install sensors. 3.3 Tools required Tools required to install and maintain a Campbell Scientific tower: Shovel Rake Open end wrenches: 3/8 in, 7/16 in, 1/2 in, (2) 9/16 in Socket wrench set...
Position the height of the opening as low as possible, but high enough to avoid splashing from the ground. Wind shields, such as Campbell Scientific 260 953 Alter-Type Rain Gage Wind Screen, are recommended for open areas.
The UT6 and UT10 towers provide a versatile mount for sensors, antennas, solar panels, environmental enclosures, radiation shields, and mounting crossarms. The 2m (6 ft) height of the UT6 and 3m (10 ft) height of the UT10 allows for wind measurements at each height. The main tower frame (FIGURE 5-1 (p.

2 square feet. The amount of wind load that this mount can withstand is affected by the quality of anchoring and installation, soil type, and the number, type, and location of instruments fastened to the tower. UT6 and UT10 Universal Towers...
The tower provides a support structure for mounting the weather station components. FIGURE 7- (p. 9) shows a typical tower equipped with an instrumentation enclosure, meteorological sensors, and a solar panel. FIGURE 7-1. Weather tower UT6 and UT10 Universal Towers...
CAUTION: It is common for air to be trapped behind the knee portion of a J-bolt. Use a stick or rod to stir and tamp around each J-bolt to ensure proper anchoring. UT6 and UT10 Universal Towers...
Loosen the two bolts at the top of the tower and insert the mast. For the UT6 at a 1.8 m mounting height, or the UT10 at 3 m, rest the bell reducer against the top of the tower. Tighten the two bolts to secure the mast.

Align the hole in the bottom of each mounting foot with one of the J-bolts in the concrete base. Slide the tower onto the J-bolts. 5. Place a 5/8-inch flat washer, a 5/8-inch split washer, and a 5/8-inch nut on each J-bolt. Do not tighten the nut (FIGURE 7-6 (p. 14)). UT6 and UT10 Universal Towers...

Mounting sensors on a crossarm allows the sensor to be moved away from the midline of the tower, reducing the effects of the mount on the sensor measurement. Campbell Scientific provides a variety of lengths in aluminum or stainless steel. Table 7-1 (p. 19) shows the different lengths available.
