Model 020C Wind Direction Sensor
1. Introduction
The Model 020C Wind Direction Sensor measures azimuth with research-
grade 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.
