Precautions

DANGER — MANY HAZARDS ARE ASSOCIATED WITH INSTALLING, USING, MAINTAINING, AND WORKING ON OR AROUND

TRIPODS, TOWERS, AND ANY ATTACHMENTS TO TRIPODS AND TOWERS SUCH AS SENSORS, CROSSARMS, ENCLOSURES,
ANTENNAS, ETC. FAILURE TO PROPERLY AND COMPLETELY ASSEMBLE, INSTALL, OPERATE, USE, AND MAINTAIN TRIPODS,

TOWERS, AND ATTACHMENTS, AND FAILURE TO HEED WARNINGS, INCREASES THE RISK OF DEATH, ACCIDENT, SERIOUS
INJURY, PROPERTY DAMAGE, AND PRODUCT FAILURE. TAKE ALL REASONABLE PRECAUTIONS TO AVOID THESE HAZARDS.
CHECK WITH YOUR ORGANIZATION'S SAFETY COORDINATOR (OR POLICY) FOR PROCEDURES AND REQUIRED PROTECTIVE
EQUIPMENT PRIOR TO PERFORMING ANY WORK.

Use tripods, towers, and attachments to tripods and towers only for purposes for which they are designed. Do not exceed design
limits. Be familiar and comply with all instructions provided in product manuals. Manuals are available at www.campbellsci.com or
by telephoning [phone] (USA). You are responsible for conformance with governing codes and regulations, including safety
regulations, and the integrity and location of structures or land to which towers, tripods, and any attachments are attached. Installation
sites should be evaluated and approved by a qualified engineer. If questions or concerns arise regarding installation, use, or
maintenance of tripods, towers, attachments, or electrical connections, consult with a licensed and qualified engineer or electrician.

General

• Prior to performing site or installation work, obtain required approvals and permits. Comply

with all governing structure-height regulations, such as those of the FAA in the USA.

• Use only qualified personnel for installation, use, and maintenance of tripods and towers, and

any attachments to tripods and towers. The use of licensed and qualified contractors is highly
recommended.

• Read all applicable instructions carefully and understand procedures thoroughly before

beginning work.

• Wear a hardhat and eye protection, and take other appropriate safety precautions while

working on or around tripods and towers.

• Do not climb tripods or towers at any time, and prohibit climbing by other persons. Take

reasonable precautions to secure tripod and tower sites from trespassers.

• Use only manufacturer recommended parts, materials, and tools.

Utility and Electrical

• You can be killed or sustain serious bodily injury if the tripod, tower, or attachments you are

installing, constructing, using, or maintaining, or a tool, stake, or anchor, come in contact with
overhead or underground utility lines.

• Maintain a distance of at least one-and-one-half times structure height, 20 feet, or the distance

required by applicable law, whichever is greater, between overhead utility lines and the
structure (tripod, tower, attachments, or tools).

• Prior to performing site or installation work, inform all utility companies and have all

underground utilities marked.

• Comply with all electrical codes. Electrical equipment and related grounding devices should

be installed by a licensed and qualified electrician.

Elevated Work and Weather

• Exercise extreme caution when performing elevated work.

• Use appropriate equipment and safety practices.

• During installation and maintenance, keep tower and tripod sites clear of un-trained or non-

essential personnel. Take precautions to prevent elevated tools and objects from dropping.

• Do not perform any work in inclement weather, including wind, rain, snow, lightning, etc.

Maintenance

• Periodically (at least yearly) check for wear and damage, including corrosion, stress cracks,

frayed cables, loose cable clamps, cable tightness, etc. and take necessary corrective actions.

• Periodically (at least yearly) check electrical ground connections.

WHILE EVERY ATTEMPT IS MADE TO EMBODY THE HIGHEST DEGREE OF SAFETY IN ALL CAMPBELL SCIENTIFIC PRODUCTS,
THE CUSTOMER ASSUMES ALL RISK FROM ANY INJURY RESULTING FROM IMPROPER INSTALLATION, USE, OR
MAINTENANCE OF TRIPODS, TOWERS, OR ATTACHMENTS TO TRIPODS AND TOWERS SUCH AS SENSORS, CROSSARMS,
ENCLOSURES, ANTENNAS, ETC.

NOTE

Met One 034B Wind Set

1. Introduction

The 034B Wind Set combines a 3-cup anemometer and vane into a single
integrated package to measure wind speed and direction. It is cabled for use
with our dataloggers, and can provide measurements for a variety of
applications.

This manual provides information only for CRBasic dataloggers.
It is also compatible with most of our retired Edlog dataloggers.
For Edlog datalogger support, see an older manual at

www.campbellsci.com/old-manuals or contact a Campbell

Scientific application engineer for assistance.

2. Cautionary Statements

• READ AND UNDERSTAND the Precautions section at the front of this

manual.

• The 034B is a precision instrument. Please handle it with care.

• If the 034B is to be installed at heights over 6 feet, be familiar with tower

safety and follow safe tower climbing procedures.

• Danger—Use extreme care when working near overhead electrical wires.

Check for overhead wires before mounting the 034B or before raising a
tower.

• The set screw holes must be covered with labels to prevent corrosion and

assure the warranty.

• The black outer jacket of the cable is Santoprene® rubber. This

compound was chosen for its resistance to temperature extremes, moisture,
and UV degradation. However, this jacket will support combustion in air.
It is rated as slow burning when tested according to U.L. 94 H.B. and will
pass FMVSS302. Local fire codes may preclude its use inside buildings.

3. Initial Inspection

Upon receipt of the 034B, inspect the packaging and contents for damage. File
damage claims with the shipping company. Immediately check package
contents against the shipping documentation (see Section 3.1, Ships With List).
Contact Campbell Scientific about any discrepancies.

The model number and cable length are printed on a label at the connection end
of the cable. Check this information against the shipping documents to ensure
the expected product and cable length are received.

4. Quickstart

4.1 Step 1—Mount the Sensor

The 034B Wind Set ships with:

(1) 1/16-inch Allen wrench
(1) Bushing from Met One
(1) Calibration Sheet
(3) Direction hub stickers
(1) ResourceDVD
(1) Wind Vane
(1) Sensor cable of user-specified length

Tools required:

• 1/2-inch open-end wrench (for CM220)

• 5/64-inch and 1/16-inch Allen wrenches

• compass and declination angle for the site (see Appendix C)

• small screw driver provided with datalogger

• UV resistant cable ties

• small pair of diagonal-cutting pliers

• 6-inch to 10-inch torpedo level

This quick start installs the 034B using:

• 17953, 1 x 1 inch NU-RAIL Crossover Fitting (FIGURE 4-1), or

• CM220, Right-Angle Mounting Kit (FIGURE 4-2)

Please review Section 7, Installation, for siting and other guidelines.

1. Fully insert vane arm into hub (see FIGURE 4-1).

2. Align vane with center axis of sensor (see FIGURE 4-1).

3. Using the Allen wrench, tighten set screws at the top of the hub (see

FIGURE 4-1).

4. Cover the set screw hole with one of the small round stickers included

with the 034B. One of these labels is already installed on the hub covering
the set screw that attaches the hub to the sensor. Extra labels are included
with the 034B to recover the holes if the sensor has to be disassembled for
maintenance.

The set screw holes must be covered with the labels to
prevent corrosion and assure the warranty.

5. Mount a CM200-series crossarm to the tripod or tower.

6. Orient the crossarm North-South, with the CM220 mount or 17953 NU-

RAIL on the North end. Appendix C contains detailed information on

Met One 034B Wind Set

determining True North using a compass and the magnetic declination for
the site.

7. Remove the alignment screw at the base of the 034B (FIGURE 4-1).

8. Insert the 034B into the aluminum bushing provided with the sensor (see

FIGURE 4-1).

9. Align the hole in the bushing with that in the 034B base and replace the

screw (see FIGURE 4-1).

10. Insert the 034B/bushing into the NU-RAIL fitting (FIGURE 4-1) or the

CM220’s U-bolt (FIGURE 4-2).

11. Align the sensor so that the counter weight points to true South and tighten

the set screws on the NU-RAIL or U-bolts on the CM220. Final sensor
orientation is done after the datalogger has been programmed to measure
wind direction as described in Appendix C.

12. Remove the shoulder screw to allow the vane to rotate (see FIGURE 4-1).

13. Attach the sensor cable to the six pin male connector on the 034B. Make

sure the connector is properly keyed. Finger tighten the knurled ring.

14. Route the sensor cable along the underside of the crossarm to the tripod or

tower, and to the instrument enclosure.

15. Secure the cable to the crossarm and tripod or tower using cable ties.
