Detailed Description

The 05106 Wind Monitor-MA is made out of rigid UV-stabilized thermoplastic with stainless steel and anodized aluminum fittings. The thermoplastic material resists corrosion from sea air environments and atmospheric pollutants. It uses stainless-steel precision-grade ball bearings for the propeller shaft and vertical shaft bearings.

To make it more durable in offshore and marine applications, the 05106 has waterproof bearing lubricant and a sealed, heavy-duty cable pigtail instead of the standard junction box.

The 05106 measures wind speed with a helicoid-shaped, four-blade propeller. Rotation of the propeller produces an ac sine wave that has a frequency directly proportional to wind speed. The ac signal is induced in a transducer coil by a six-pole magnet mounted on the propeller shaft. The coil resides on the non-rotating central portion of the main mounting assembly, eliminating the need for slip rings and brushes.

Wind direction is sensed by the orientation of the fuselage-shaped sensor body, which is connected to an internal potentiometer. The data logger applies a known precision excitation voltage to the potentiometer element. The output is an analog voltage signal directly proportional to the azimuth angle.

Additional Compatibility Information

Mounting

The Wind Monitors can be attached to a CM202, CM204, or CM206 crossarm via a 17953 NU-RAIL fitting or CM220 Right Angle Mounting Bracket. Alternatively, the Wind Monitors can be attached to the top of our stainless-steel tripods via the CM216 Sensor Mounting Kit.

Wind Profile Studies

Wind profile studies measure many wind sensors. For these applications, the LLAC4 4-Channel Low Level AC Conversion Module can be used to increase the number of Wind Monitors measured by one data logger. The LLAC4 allows data logger control ports to read the wind speed sensor’s ac signals instead of using pulse channels. Data loggers compatible with the LLAC4 are the CR200(X) series (ac signal ≤1 kHz only), CR800, CR850, CR1000, CR3000, and CR5000.

Data Logger Considerations

The 05106's propeller uses one pulse count channel on the data logger. Its wind vane requires one single-ended channel and access to an excitation channel (the excitation channel can be shared with other high impedance sensors).

Programming

The 05106's propeller is measured by the PulseCount Instruction in CRBasic and by Instruction 3 (Pulse Count) in Edlog. The wind vane is measured by the BrHalf Instruction in CRBasic and by Instruction 4 (Excite-Delay-SE) in Edlog. The measurements are typically processed for output with the Wind Vector instruction (not present in the CR500 or CR9000 but is present in the CR9000X).

Expand AllCollapse All

  1. Is a separate extension cable for a 05106-L available? The current cable is approximately 13 ft long, and it would be helpful to extend the cable another 20 ft.

    Campbell Scientific does not sell an extension cable. A replacement cable can be ordered and built to the desired length (pn 05106CBL-L). This replacement cable has a connector that mates with the connector at the end of the 3 ft cable attached to the 05106-L.

  2. If an existing wind set is replaced with a wind monitor (05103-L, 05103-45-L, 05106-L, 05305-L), will more than the multiplier and offset have to be changed in the data logger program?

    The measurement instructions will likely remain the same. However, in addition to the multiplier and offset, the type of pulse may change for the wind speed, and the excitation voltage may change for the wind direction. For an explanation of how the data logger needs to be programmed, see the instruction manual.

  3. If the speed indicator on a wind monitor stops working, is there a part that can be replaced, or does the whole unit need to be replaced?

    This depends on what is broken. Typically, Campbell Scientific can repair the unit, and the user does not have to purchase a new one.

  4. Can the output of a wind monitor (05103-L, 05103-45-L, 05106-L, or 05305-L) be changed to analog dc voltage?

    No.

  5. What is the power consumption (mA) of the 05103-L, 05103-45-L, 05305-L, and 05106-L anemometers?

    The short answer is less than 0.01 mA. The wind speed signal requires no power. The wind direction portion of the sensor only uses a maximum of 0.5 mA when excited with 5 Vdc, and then it is only on for 0.016 s for every measurement. When the wind direction is measured every second (typical), the average current drain is less than 0.01 mA.

  6. What is the procedure for orienting a wind monitor (05103-L, 05103-45-L, 05305-L, or 05106-L) to the cardinal directions so that the wind direction readings are correct?

    Orientation of the wind monitor is done after the data logger has been programmed, and the location of True North has been determined. True North is usually found by reading a magnetic compass and applying the correction for magnetic declination, where magnetic declination is the number of degrees between True North and Magnetic North. Magnetic declination for a specific site can be obtained from a USFA map, local airport, or through a computer service.

  7. If a sensor automatically ships with a calibration sheet, what information is included on it?

    The information included on a calibration sheet differs with each sensor. For some sensors, the sheet contains coefficients necessary to program a data logger. For other sensors, the calibration sheet is a pass/fail report.

  8. What are the different cable length choices available for Campbell Scientific sensors?

    Most Campbell Scientific sensors are available as an –L, which indicates a user-specified cable length. If a sensor is listed as an –LX model (where “X” is some other character), that sensor’s cable has a user-specified length, but it terminates with a specific connector for a unique system:

    • An –LC model has a user-specified cable length for connection to an ET107, CS110, or retired Metdata1.
    • An –LQ model has a user-specified cable length for connection to a RAWS-P weather station.

    If a sensor does not have an –L or other –LX designation after the main model number, the sensor has a set cable length. The cable length is listed at the end of the Description field in the product’s Ordering information. For example, the 034B-ET model has a description of “Met One Wind Set for ET Station, 67 inch Cable.” Products with a set cable length terminate, as a default, with pigtails.

    If a cable terminates with a special connector for a unique system, the end of the model number designates which system. For example, the 034B-ET model designates the sensor as a 034B for an ET107 system.

    • –ET models terminate with the connector for an ET107 weather station.
    • –ETM models terminate with the connector for an ET107 weather station, but they also include a special system mounting, which is often convenient when purchasing a replacement part.
    • –QD models terminate with the connector for a RAWS-F Quick Deployment Station.
    • –PW models terminate with the connector for a PWENC or pre-wired system.
  9. Where are the available cable termination options listed for a particular sensor?

    Not every sensor has different cable termination options. The options available for a particular sensor can be checked by looking in two places in the Ordering information area of the sensor product page:

    • Model number
    • Cable Termination Options list

    If a sensor is offered in an –ET, –ETM, –LC, –LQ, or –QD version, that option’s availability is reflected in the sensor model number. For example, the 034B is offered as the 034B-ET, 034B-ETM, 034B-LC, 034B-LQ, and 034B-QD.

    All of the other cable termination options, if available, are listed on the Ordering information area of the sensor product page under “Cable Termination Options.” For example, the 034B-L Wind Set is offered with the –CWS, –PT, and –PW options, as shown in the Ordering information area of the 034B-L product page.

    Note: As newer products are added to our inventory, typically, we will list multiple cable termination options under a single sensor model rather than creating multiple model numbers. For example, the HC2S3-L has a –C cable termination option for connecting it to a CS110 instead of offering an HC2S3-LC model. 

  10. Using Short Cut, how can the average wind direction be calculated?
    1. Using Short Cut, click the applicable wind direction sensor in the Selected Sensors list of the Outputs screen.
    2. The two output options enabled are Sample and WindVector. Select WindVector.
    3. The WindVector instruction has output options. Select an option with mean wind direction in it.
