The W200 series windvanes are high quality instruments for measuring wind direction, which have proven themselves over many years in applications from general meteorology to wind assessment. Two basic types are available: The W200P and W200P/L. The W200P is a high resolution instrument fitted with a 1K ohm potentiometer of robust design. The W200P/L is a "Light Duty" instrument fitted with a low-torque 2K ohm potentiometer, and is more responsive to light winds than the standard W200P (but is less robust).

Our windvanes are robustly constructed using weather resisting plastics, anodised aluminium and stainless steels enabling them to withstand continuous exposure to the weather including marine environments. The fixed-reference W200 Series Windvanes all share the same basic construction and use the same F20 series Fins (vane-arms), different internal modules/components are used to provide different output signals. The Self-Referencing SRW1 Series Windvanes (special order product) which include an internal compass system are also available and are poular for use on mobile platforms such as buoys at sea.   Available windvane types include: Potentiometric (1K Pot) - W200P Windvane (A durable, robust windvane ideal for most data-loggers and demanding applications) Potentiometric (2K Pot) - W200P/L Windvane (Low-Torque, Light Duty) (also ideal for most data-loggers and for Light Duty applications like general meteorology, agrometeorology etc) Self-Referencing Encoder (Gray-code output) - SRW1G Windvane Options common to all the windvanes include: marine versions/fins mounting adaptors anti-icing heaters (for the W200 Series). Unlike some other manufacturers, we do not manufacture a "combined" wind speed and wind direction sensor. With our product range you have the flexibility to chose an anemometer and windvane with appropriate output signals and mount them together at the top of a mast using one our 405-1 series mounting arms.
