Product Details

Wind direction data is an important component of any wind or solar resource assessment campaign, and it is also vital for power performance tests and site monitoring once a project is operational. RNRG offers both heated and unheated wind direction vanes, ensuring access to reliable wind direction data regardless of environmental conditions.

NRG 200M Wind Vane

NRG Systems’ 200M Wind Direction Vane brings significant upgrades to the proven design of our 200P Wind Direction Vane.

NEW IN THE 200M

No Dead Band: The 200M has 360° continuous measurement, whereas the 200P has an 8° max. dead band centered on 0°.
Reduced Sensor Uncertainty: The 200M's sensor uncertainty is ±1.6° across virtually its full range, whereas the 200P's sensor uncertainty outside the dead band region is ±4.3°.
Improved Vane Orientation Precision and Repeatability: The 200M's improved mounting system makes it easier to precisely determine sensor orientation once installed on a boom.
Firmer Mounting Connection: The 200M's new mounting system enables a firmer connection between the vane and mounting boom, making it less likely that vane orientation will drift over time.
Improved Protection Against Water and Dust Ingress: The 200M's bearing and electronics capsules are fully sealed against water and dust ingress, making it less likely that corrosion or dust will damage the sensor over time.
Transparent Records of Sensor Response and Quality: Factory calibration certificates with sensor-specific scale and offset values will be available at no extra cost.

MAINTAINED FROM THE 200P

Proven Aerodynamic Performance and Robustness: The 200M utilizes the same black, UV-stabilized injection molded plastic vane wing and sensor body that the 200P has been proving in the field for decades.
Easy Sensor Traceability: Individual unit serialization makes it easier to keep track of your wind vane's unique history and ties it to its sensor-specific slope and offset values determined during the manufacturing process or in a wind tunnel.
Easy Compatibility: The 200M’s simple voltage output is compatible with all industry-standard data loggers, including legacy NRG loggers, and is designed to work seamlessly with the NRG SymphoniePRO® Data Logger.
Low Power Draw: With a current draw of 0.9° to 0.9° to
