Frequently Asked Questions FAQs

Frequently Asked Questions: 03101-L


  1. Instead of purchasing the entire 03001-L R. M. Young Wind Sentry Set, can I purchase just the Wind Sentry anemometer or Wind Sentry wind direction sensor to replace a bad unit from a previously purchased set?

    The sensor could be sent in for repair if it isn't a total loss. Remember to call for an RMA (return material authorization) number before sending in the sensor.
    • Replacing the wind speed sensor:
      • Purchase a 03101-L to replace the anemometer. This unit comes with a pipe mount adapter that can be removed and used with the 40-cm Wind Sentry crossarm. Remember to purchase the correct cable length to match the damaged sensor.
    • Replacing the wind direction sensor
      • Additional options come with this sensor. Don't forget the cable length!
      • Purchase a 03301-L-NM for just the wind-direction sensor and cable.
      • Purchase a 03301-L-SM to add a wind-direction sensor to an existing 03101-L anemometer and the 40-cm Wind Sentry crossarm.
      • Purchase a 03301-L-P for a wind-direction sensor with a pipe-mount adapter.




  2. I am currently using a Met-One 014A; however, I have to replace the reed switches and bearings regularly. Due to the design of the Met-one and the location of my field site, I am experiencing problems due to soil accumulating inside the assembly cup. I am collecting data on a 12V system with a CR23X. How does the R.M. Young 03101-L compare in both durability and price?

    Before considering replacing your 014A-L please read over the specifications for both sensors. See if the RM Young 03101-L meets your specifications.

    RM Young 03101 Specifications
    Accuracy: ±1.1 mph (0.5 m/s)
    Gust survival: 134 mph (60 m/s)
    Threshold (w/ shielded bearings): 1.1 mph (0.5 m/s)
    Distance constant: 7.5 ft (63% recovery)

    014A Specifications
    Operating range: 0 to 100 mph (0 to 45 m/s)
    Threshold: 1 mph (0.45 m/s)
    Accuracy: ±0.25 mph (0.11 m/s) or ±1.5%
    Distance constant (aluminum cups): 15 ft (4.6 m)
    Distance constant (optional fast response Lexan cups): < 5 ft (1.5 m)

    Any mechanical wind speed sensor will need to have its bearings replaced on a regular basis.
    The RM Young 03101-L is a less expensive sensor and does not have a reed switch to replace. It’s easier to work on plus the bearings are less expensive. The turret covering the bearings is longer and protects the bearings better from dust and debris. See the RM Young manual for instructions on testing wind speed bearing performance in the field with paper clips. The cups and sensor body are plastic and more fragile so careful handling is required but hold up well once the sensor is installed.

    Replacing a 014A-L with a 03101-L might require a new right angle mount for mounting to an existing cross arm. The 03101-L comes with a ¾” pipe vs. the 1” pipe with the 014A-L.



  3. Is this unit capable of delivering a 0-5VDC square wave output for the wind speed?

    No. But using a LLAC4 will convert the AC signal for up to four 03101-L sensors (and other AC output anemometers) to individual 0-5VDC TTL level square wave outputs. Please see information on the LLAC4 on CSI’s website for specifications.
