Constructed of rugged Lexan cups molded in one piece for repeatable performance. Includes calibration certificate.

A four-pole magnet induces a sine wave voltage into a coil producing an output signal with frequency proportional to wind speed. The #40C is constructed of rugged Lexan cups molded in one piece for repeatable performance. A rubber terminal boot is included.

Features
This anemometer is often used for wind resource assessment for wind turbines, they are 1% accuracy and have a resolution better than 0.1m/s to match the IEC-61400-12 standards for wind measurement and wind turbine performance analysis.

The #40C anemometers are manufactured with exceptional quality control meeting new standards- all units are tested mechanically and electronically before shipping.

This anemometer is compatible with our GSM wind monitoring system only

This product is for the hobbyist enthusiast, when you know what you are doing and don't mind getting your hands dirty a bit... Community WINDLogger is here.

So what is it?

It is the well known WINDLogger that has been manufactured over the last 10 years, the only difference you have to assemble it yourself. Everything else is exactly the same, same firmware, same quality, same data. 

What do you get?

You get the WINDLogger electronic circuit board, the battery holder, the battery lead connector and the screws to attach to the circuit board. 

What do you need to add?

You need to find your own IP rated enclosure to house the WINDLogger electronics, cable glands and of course making sure you do a great job at assembling it!

You will also need to add a good microSD card with less than 2GB capacity - this is important! The smaller the card, the less power it uses. 

Or you can buy it from us, a proper industrial grade memory card to work on extreme conditions and with a really good writing cycle specs. Good industrial and reliable memory cards are not cheap.

What about support?

We will support you via email. If for whatever reason you feel unsure about the community edition, then please have a look at WINDTracker or WINDLogger itself.

• The new LeWL WindLogger has been manufactured since 2008. We have sold thousands of these little wind data loggers all over the world and they have an excellent reputation for their stability, accuracy and endurance.

  
  The new WindLogger has been re-designed with major enhancements, thanks to the small wind enthusiastic community. We have listened to their feedback and have made several improvements: Simpler than ever installation, just plug the Pro-D anemometer into the internal 6P4C connector. If you use any other type of anemometer, that is ok too. You can connect it directly to its internal sensor input connection block. Automatic anemometer detection system. The new WindLogger will let you know if there's an anemometer connected and working before leaving site.

• The new WindTracker is one of the simplest to use wind site assessment tools out there, yet it shares the high specification of the more advanced new WindLogger. 
  The new WindTracker automatically measures all the wind statistics for you. Just connect the wind sensor and let the Windtracker run. (No setup required if sensor bought from us)

  When you are ready to collect the information, just pop in the microSD card (supplied with the logger) and the WindTracker will transfer all of its data statistics to a simple text file on the memory card. Upload this file to our FREE online reporting tool and you'll have a simple yet very informative wind report for small scale wind turbines.

• This kit utilises the new WindLogger feature of having 2 anemometer inputs recording data simultaneously, so you can measure the wind speed at two different heights.

  What is this good for? Mainly to calculate wind shear or more commonly used to extrapolate wind speed at a higher heights. Imagine you want to know the wind speed at 23 meters but your wind mast only reaches up to 18 meters. You could connect the top anemometer at 18 meters and the second one at 12 meters for example. With these two values you could extrapolate your wind speed at 23 meters without having to physically measure it. Just keep in mind it is not recommended to extrapolate more than 2/3rds of the top measurement point. 

  This kit brings all the key features from a professional wind monitoring system but at an entry level price. The kit comes with:

   • new LeWL WindLogger
   • 1 x Combined anemometer with wind vane, with 13 meters of cable and attachment support for the mast
   • 1 x Vortex anemometer with 10m of sensor cable
   • Quick guide installation
   • Industrial grade batteries and industrial grade microSD card.

• This wind kit will give you an accurate representation of the potential of your site for a small scale wind turbine. It includes one of the best wind speed and direction sensors (for its price!) you can buy today.

  The new WindTracker wind speed and direction kit comes with all you need to start measuring accurately the potential of your new site. It does even come with the accessories to attach the anemometer to a pole. You will need to source your own small wind mast, we have seen amateur radio masts (10 and 15 meters) used for this and they work great. Alternatively, you can always use a scaffold pole (make sure you have proper cable guys in place)

  You will receive with this kit:
   • new WindTracker
   • Pro-D Anemometer with 13 meters of cable and attachment support for the mast
   • Quick guide installation
   • Industrial grade batteries and Industrial grade microSD card.
