Anemometer
Affordable and accurate non-directional heated needle anemometer for low wind speeds. The East 30 Sensors anemometer uses heat transfer to monitor air flow as it passes the needle. It is appropriate for many settings including:, Air flow monitoring in greenhouses, Point wind speed determination, Wind speed determination in all types of plant canopies, Low wind speed monitoring. The East 30 Sensors anemometer is designed to be simple and robust while still providing very accurate data. This sensor consists of a thermistor and a heating element to measure the heat transfer associated with air movement across the needle. This is then calibrated to wind speed. Accuracy will decrease significantly if the needle is wet or dirty.

The Heated Needle Anemometer is designed to be robust and reliable, especially in low wind speeds. It is intended to be used with a Campbell Scientific Datalogger. For more information see datalogger compatibility or if you have no experience with these dataloggers see Turn-Key Solutions.
The Heated Needle Anemometer is calibrated in the factory, and then is ready to use in conjunction with a Campbell Scientific datalogger. No additional accessories are needed.
The East 30 Sensors Anemometer uses a durable configuration with a stainless-steel needle to measure windspeed. This sensor uses the heat transfer to determine non-directional windspeed across the needle in a range from 0-15 m/sec. To take a measurement, a baseline temperature is recorded followed by a precisely timed heating step, during which temperature is recorded. The difference is then taken between the baseline temperature and the final temperature. By using the same heating time and monitoring the change in temperature, wind speed can be calculated using the provided factory calibration.
