Celebrating more than 50 years manufacturing & servicing High Quality Vector Instruments Anemometers and Windvanes at Windspeed Ltd
/SE and /WR3 Severe Environment / Marine (Offshore) Versions
of Anemometers, Windvanes, Rotors
 
Severe Environment Anemometer variant  
 The "Severe Environment" ( /SE ) option is now available for the First Class A100 Series Anemometers for applications where extra measures are necessary to improve performance/reliability in extreme conditions.

The well proven First Class R30 rotor has been subtly refined to produce a variant which retains all of the external features/dimensions of the original R30 rotor and therefore maintains it's First Class performance characteristics.

The subtle rotor refinements are designed to enhance operation and reliability in arduous conditions, and together with additional improvements to the anemometer body shell sealing the "/SE" option is an ideal choice for A100 Series Anemometers which will be used in Severe Environments where First Class performance is required together with high accuracy and reliable performance, such as in Offshore Wind Assessment or Wind Turbine Control applications.

APPLICATIONS:

- Off-Shore and Coastal/Marine
- Desert/Dusty Environments
- Cold/Icing Environments
- Dirty Industrial sites


Key Features:

** First Class Performance
- Bearings, External Rotor/Cup dimensions, and anemometer body dimensions are identical to the standard product so the First Class performance of the standard R30 rotor is maintained for this variant.

** Enhanced Sealing - Close tolerance features on the rotor hub together with improved anemometer top-seal, and additional bearing protection, significantly reduce the likelihood of water/sand/dust entering the bearings which prolongs bearing life and hence maintains accuracy/calibration for longer.

** Black cups and Anti-icing heater
- Provides improved operation in low-temperature & icing conditions, incorporating 12V or 24V "internal" HE-4 heater to ensure bearings/rotor continue to rotate, and black rotor cups for improved natural (solar) cup de-icing.

** Improved Rotor Gravity/Locking Catch
- The proven standard gravity catch design has served well for many years, however the rotor supplied as part of the /SE option includes additional refinements to yield more consistent locking of the rotor assembly to the anemometer body, especially when the rotor is to be fitted when the anemometer body is not vertical such as situations where the rotor needs to be fitted at a time when the anemometer is close to the horizontal (for example: when anemometers are assembled to booms on tall guyed towers resting along the ground before they are raised).

** Additional Rotor Locking-Screw
- A clamping screw supplements the improved rotor gravity catch to ensure reliable fixing of the rotor in applications where high levels of shock and vibration might occur (e.g. Off-Shore masts, very tall masts, or during raising of guyed masts/towers).

** Superior Performance compared to older "/WR" (marine) Rotor variants
- Tests indicate that anemometers with the "/SE" option perform significantly better than our older "/WR" (marine) variants in terms of excluding water/sand/dust, while providing First Class performance (which the older "/WR" variants did not). Standard anemometer electrical/performance specifications & dimensions are unaffected when the /SE option is specified.

To order, add the "/SE" suffix to the A100 Series Anemometer catalog number.

A matching /SE option for W200 Series Windvanes is also now available.

WARNING: These instruments must not be submerged in water/sea-water, and are not suitable for use where the rotor/cups/fin may be continually/regularly impacted by waves or material/objects thrown up by waves/wind. Unsuitable installation/positioning close to the sea surface, or where tidal/storm-surge changes in sea-level may cause the instrument to be immersed in water, or inappropriate installation very close to the surface of the sea, may all lead to water-ingress/corrosion and/or impact-damage and any such damage is NOT covered by the product warranty/guarantee as this is considered to be misuse of the product.

/WR3 Marine Option


Also available is the alternative "/WR3" option, which is a lower-cost "marine" option which is also now available for both A100 Series Anemometers and W200P Series Windvanes. The /WR3 is an up-rated/improved version of the older/discontinued "/WR" marine option, and includes elements of both the /SE (above) and the discontinued /WR option to give increased protection against water/dirt ingress. /WR3 eliminates the old "rubber touching seals" of the /WR option, and instead includes a close-fitting metal seal (non-touching) plus a side-clamping screw on the rotor/fin for additional security in severe conditions (see images below).

Note that the /WR3 option does not include an anti-icing heater, and is not suitable for "First Class" wind-assessment applications.
