Model 020C Wind Direction Sensor

1. Introduction

The Model 020C Wind Direction Sensor measures azimuth with research­grade accuracy and precision. Campbell Scientific recommends the 020C for
wind farm power performance research, such as on eighty- and ninety-meter
met towers. The 020C is especially suited to applications requiring a low
starting threshold, a high damping ratio, or a short delay distance.

Before installing the 020C, please study

• Section 2, Cautionary Statements

• Section 3, Initial Inspection

• Section 4, Quickstart

2. Cautionary Statements

• The 020C is a precision instrument. Please handle it with care.

• If the 020C is to be installed at heights over six 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 020C or before raising a
tower.

3. Initial Inspection

• Upon receipt of the 020C, inspect packaging and contents for damage.

File damage claims with the shipping company.

• 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 Installation

Figure 4-1 shows the 020C installed with a CM220 Right Angle Mounting Kit.

Please review Section 7, Installation, for complete guidelines. Install the 020C

using:

• 28798 020C Mounting Bushing

• CM220 Right-Angle Mounting Kit, or

• 1049 ¾ x 1 inch NURAIL Crossover Fitting

1. Remove the orientation screw from the base of the sensor column. Place

the sensor column in the bushing such that the hole in the bushing aligns
with the hole just vacated by the orientation screw. Replace the screw and
tighten until snug. Do not over-tighten.

2. Place the sensor and bushing in the right-angle mounting bracket or

Nurail

fitting.

3. Rotate the sensor and bushing such that the vane and orientation screw

point true south, ensuring that the notches on the sensor hub and column
align.

4. Tighten the u-bolt (CM220) or set screws (pn 1049).

5. Attach the sensor cable to the six-pin male connector on the 020C.
