Mechanical Wind Sensors
Which model Wind Monitor should I choose?
The standard Model 05103 is recommended for general meteorology use. A number of special models exist to satisfy unique applications:
Heavy Duty sensor with enlarged shaft and ceramic bearings for extended bearing life
Marine use and exposure to saltwater, features ceramic bearings and waterproof cable.
Meets air quality monitoring requirements established by US EPA for PSD
Serial output with digital encoder for wind direction (no potentiometer)
Wind Monitor Alpine
Ice-resistant coating aids performance in freezing temperatures
Intrinsically-safe for use in hazardous environments
How do I calibrate my Wind Monitor?
The best method of calibrating any wind sensor is using a Wind Tunnel. This can be done at YOUNG or other facilities for a nominal fee. A field evaluation of Wind Monitor sensors can be done using the Anemometer Drive and other calibration accessories available from YOUNG.
How often should I replace ball bearings in my wind sensor?
Bearing replacement interval will vary depending on use. In normal use, bearings will often last 5 years or more. Exposure to harsh environments such as high wind, sea water and dust will shorten bearing life. Good practice is to inspect bearings annually. Replacement is indicated if bearing rotation is abnormally noisy or if high torque is noted. Wind speed bearing replacement is a simple procedure that can be performed in minutes. Instructions are in the manual. Your YOUNG supplier can assist with service.
The bearings in my Wind Monitor are noisy. Is this normal?
Ceramic bearings are used in the Marine (MA), Heavy Duty (HD), and Intrinsically Safe (IS) Wind Monitors. These bearings tend to be noisier than the bearings used in other Wind Monitor models, which have little to no noise. The most important feature with the bearings in any Wind Monitor is that they are able to spin freely and do not slow abruptly. Propeller and Vane Torque devices can be used to verify sensor operation.
Ultrasonic Wind Sensors
How do I calibrate my sonic anemometer?
An accurate sonic anemometer calibration can only be done in a Wind Tunnel. This can be done at YOUNG for a nominal fee. A “zero wind” check can be done to verify that sonic electronics are operating properly with no wind present.
What is a “zero wind chamber”?
One functional test of sonic anemometers is to confirm that they report zero when no wind is present. This test is performed in a zero wind chamber. The “chamber” can be as simple as a plastic bag placed over the sensor or it can be a more elaborate fitted case; the function is the same. Remember, this check confirms a correct reading only at zero wind.
Can I repair my sonic anemometer?
Sonic anemometers are very complex instruments that require specialized equipment to service. If the problem cannot be solved through changes to operating settings, then the sensor must be returned to the factory.
Displays and Indicators
Can I repair my YOUNG display?
Repairs to electronic products (displays, barometers, etc…) must be done by a qualified technician. Only YOUNG personnel or trained suppliers should perform these repairs. Any attempt to repair a circuit board will void the warranty.
My Wind Tracker is displaying either half or twice the expected value. Why?
This is typically caused when the unit is inputting a 4-20 mA current and the input selection is incorrect. An input selection of ‘Ldi’ converts the 4-20 mA to a value of 0-50 m/s (or equivalent). An input selection of ‘Ld2’ converts the 4-20 mA to a value of 0-100 m/s (or equivalent). It is important to match the sensor output to the correct input setting (ie: ‘Ld2’ setting with a 05103L that has a 0-100 m/s output scaling).
Temperature and Humidity
Can the Temperature/Humidity filter be cleaned and/or how often should it be changed?
Periodic inspection of the filter is recommended to ensure that no dust or particulates have accumulated on the surface that could impair performance. It is suggested that this be performed on an annual basis. More frequent inspections may be necessary in an environment with more dust/particulates in the air. Once dust or particulates have accumulated on the filter it is recommended that it be replaced. Although it may be possible to clean the surface of the filter the pores that allow the filter to ‘breathe’ are nearly impossible to clean and, as a result, may still impair the performance of the sensor.
Precipitation and Pressure
My barometer doesn’t agree with the barometer at the airport. Is something wrong?
Since air density varies with altitude, barometers are commonly normalized to give the equivalent sea-level value. Instructions about how to correct your barometer can be found here.
My Tipping Bucket Rain Gauge is not reporting precipitation correctly. What could cause this?
Side to side motion of the gauge could inadvertently cause the sensor ‘bucket’ to move prematurely depending upon its orientation. Care must be taken upon installation to ensure the mast/pole has no vibration and that if there is any tendency for vibration the ‘bucket’ is perpendicular to such movement.
My Siphoning Precipitation Gauge is not reporting precipitation correctly. What could cause this?
A YOUNG siphoning gauge measures the precipitation volume inside a measuring chamber. As water enters this chamber air must be allowed to vent to allow the chamber to fill. Should this vent become obstructed the chamber will not fill properly. This vent is located near the top of the measuring tube (inside the outer jacket). The design of the sensor allows for adequate ventilation, but should the customer disassemble the sensor care must be taken to ensure the vent is not blocked.
The use of a YOUNG siphoning gauge requires an initial volume of water to be put into the sensor to cause it to siphon. If this initial volume of water (or water that is put in to test its operation/calibration) is entered too quickly it could result in the intake to ‘back up’ possibly causing water to enter the circuit chamber potentially causing permanent damage. Under normal operating conditions the volume of water entering the sensor is no more than a trickle. This ‘back up’ can also happen as a result of the vent described above being obstructed.
