Met One 014A Wind Speed Sensor 1. Introduction The 014A is a three-cup anemometer that monitors horizontal wind speed for the range of 0 to 45 m s–1 with a threshold of 0.45 m s–1. It connects directly to a Campbell Scientific datalogger, which measures the 014A’s pulse signal and converts the signal to engineering units (mph, m s–1, knots).

Met One 014A Wind Speed Sensor 4.2 Use SCWin to Program Datalogger and Generate Wiring Diagram Short Cut is an easy way to program your datalogger to measure the 014A and assign datalogger wiring terminals. The following procedure shows using Short Cut to program the 014A. 1. Install Short Cut by clicking on the install file icon. Get the install file from either www.campbellsci.com, the ResourceDVD, or find it in installations of LoggerNet, PC200W, PC400, or RTDAQ software. 2.
Met One 014A Wind Speed Sensor 4. Select Datalogger Model and Scan Interval (default of 5 seconds is OK for most applications). Click Next. 5. Under the Available Sensors and Devices list, select the Sensors | Meteorological | Wind Speed & Direction folder. Select 014A Wind Speed Sensor. Click to move the selection to the Selected device window. The wind speed defaults to meters/second. This can be changed by clicking the Wind Speed box and selecting one of the other options.

Met One 014A Wind Speed Sensor 7. Installation If you are programming your datalogger with Short Cut, skip Section 7.3, Wiring, and Section 7.4, Programming. Short Cut does this work for you. See Section 4, Quickstart, for a Short Cut tutorial. 7.1 Siting Locate wind sensors away from obstructions (for example, trees and buildings). As a general rule, there should be a horizontal distance of at least ten times the height of the obstruction between the sensor and the obstruction.
Met One 014A Wind Speed Sensor 7.3 Wiring The 014A is typically connected to a datalogger’s pulse port (see TABLE 7-1). TABLE 7-1.

Met One 014A Wind Speed Sensor NOTE Short Cut cannot edit programs after they are imported and edited in CRBasic Editor. A Short Cut tutorial is available in Section 4.2, Use SCWin to Program Datalogger and Generate Wiring Diagram. If you wish to import Short Cut code into either CRBasic Editor or Edlog to create or add to a customized program, follow the procedure in Appendix A.1, Importing Short Cut Code into a Program Editor.
Met One 014A Wind Speed Sensor 8.1.2 12 to 24 Month Service Replace sensor bearings. 8.1.3 24 to 36 Month Service A complete factory overhaul of the sensor is recommended. Contact Met One directly for wind speed sensor repair and recalibration service. This repair and calibration service includes disassembly and detailed inspection of all moving mechanical parts and all electronic components. Service includes replacement of bearings, shaft, and set screws as well as a functional test of the sensor.

Appendix A. Importing Short Cut Code This tutorial shows: • • How to import a Short Cut program into a program editor for additional refinement. How to import a wiring diagram from Short Cut into the comments of a custom program. A.1 Importing Short Cut Code into a Program Editor Short Cut creates files that can be imported into either CRBasic Editor or Edlog program editor. These files normally reside in the C:\campbellsci\SCWin folder and have the following extensions: • • • • • • • • .
Appendix A. Importing Short Cut Code 5. The program can now be edited, saved, and sent to the datalogger. 6. Import wiring information to the program by opening the associated .DEF file. Copy and paste the section beginning with heading “-Wiring for CRXXX–” into the CRBasic program, usually at the head of the file. After pasting, edit the information such that a ' character (single quotation mark) begins each line.
Appendix B. Example Programs B.1 Pulse Port Examples The following CR1000 and CR10X programs use a pulse port to measure the 014A every 5 seconds. The programs store mean wind speed (in m s–1) every 60 minutes. Wiring for the examples is given in TABLE B-1. TABLE B-1.

Appendix C. Sensor Maintenance C.1 Reed Switch Replacement Procedure To verify parts and locations, refer to the cable and parts diagrams (FIGURE C-2 and FIGURE C-3) and the parts list (TABLE C-1). A. Remove sensor from mounting arm and disconnect cable. B. Remove the cup assembly. C. Remove the three Philips screws at the top of the sensor and lift out the bearing mount assembly. D. Unsolder the leads of the reed switch and remove the switch from the two mounting terminals, see the parts diagram.
Appendix C. Sensor Maintenance C. Insert a right-angle type of tool, such as an Allen wrench, into bearing. Cock it slightly to one side and remove both bearings. D. Install new bearings. Be careful not to introduce dirt particles into bearings. CLEAN HANDS ONLY! DO NOT ADD LUBRICATION OF ANY KIND. E. Reassemble the sensor in reverse order. Be sure to include spacers over the bearings when replacing the shaft in the bearing mount.

Appendix D. Theory of Operation D.1 Mechanical The sensor’s cup assembly consists of three aluminum cups mounted on a cup assembly hub. A stainless steel shaft, which rotates on precision-sealed ball bearings, connects the cup assembly to a magnet assembly. When the shaft is rotated, the turning magnet assembly causes a reed switch to close. There are two contacts (reed switch closures) per revolution. The frequency of closures is linear from threshold to 45 m s–1. D.
