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 <500uAmps on SymphoniePRO wind vane channels, there is no need to increase the size of the standard power supplies you use today to accommodate the 200M.
