Overview

The UT20 is a durable instrument tower that can be used for a variety of applications. The UT20 tower provides a sturdy mount for many meteorological monitoring applications—especially fire weather stations, where a 6 m (20 ft) measurement height for wind sensors is standard. It also holds antennas, solar panels, environmental enclosures, radiation shields, and crossarms. It is a versatile instrument mount: many of the same sensor mounts that are used with either our tripods or other towers can be used with the UT20.

Technical Description

The UT20 tower includes two 3-m (10 ft) sections and one extendable mast. It has a 1.5-m (5 ft) length and a 3.175-cm (1.25 in.) outer diameter [swagged to 2.5 cm (1 in.) OD]. The 3-m sections are constructed from 2.5-cm (1 in.) OD aluminum tubing.

Top 3 m Section

This section's width is 33.3 cm (13.1 in) on a side (center of tubing to center of tubing).

Bottom 3 m Section

This section's width is 43.2 cm (17 in) on a side (center of tubing to center of tubing).

Mounting Base, Grounding Kit, and Guying Kit
This tower requires a mounting base and grounding kit. Campbell Scientific also recommends guying the UT20 with our UTGUY Guy Kit. See Ordering Info on web page for more information.

Maximum Wind Load Recommendation

B18 Base (unguyed): 177 km/h
(110 mph)
RFM18 Base (with UTGUY): 177 km/h
(110 mph)
UTBASE (unguyed): 177 km/h
(110 mph)
-NOTE-: Wind load endurance is affected by quality of anchoring and installation; guy wire tension; soil type; guy angle; and number, type, and location of instruments fastened to the tower.

Wind load recommendation assumes proper installation, proper anchoring, adequate soil, and total instrument projected area of less than 0.19 m² (2 ft²) at the height of the tower.

For the RFM18 base, the wind load recommendation also assumes that the UTGUY’s turnbuckles are preloaded just enough to equalize tension and that the tower is guyed at a 60 degree angle relative to the ground (maximum).

Enclosure Brackets

The “-TM” mount option for our environmental enclosures is used to attach our enclosures to a UT20 tower. An enclosure ordered with the “-TM” 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. This mounting bracket option uses the same three-piece brackets as the "-MM" option, except the pieces are rearranged so that the flanges are on the side of the bracket instead of in the middle. The distance between the centers of each flange needs to be 17”.

Note:
Enclosures with the "-TM" option are shipped configured for the UT10 tower. UT20 customers will need to: (1) remove the bolts attaching the bracket to the enclosure, (2) slide out the flange sections so that the distance between the center of each flange is 17", and (3) reattach the bracket to the enclosure using the original bolts.
