HR II anemometer-wind vane (cable-free)

The NKE HR II anemometer-vane is a high-precision wind sensor designed for performance sailing and advanced cruising. It provides detailed measurements of apparent wind speed and angle, as well as air temperature. It stands out for its high angular resolution (0.02°) and speed measurement linearity (approximately 1%).

The HR II wind transducer / vane anemometer provides an angular resolution of 0.02° for wind angle and a measurement linearity of approximately 1% for wind speed.

The HR II anemometer and wind vane sensor measures apparent wind speed and angle, as well as air temperature. If the installation is equipped with a speed log, it can also provide true wind speed and angle. With a Topline compass, it can display true wind direction.

The anemometer's sensitivity allows it to measure wind speeds below 2 knots and up to 80 knots.

The HR II wind transducer / vane anemometer has a measurement frequency of 200Hz for optimal responsiveness.

The HR II wind transducer/vane anemometer consumes 25mA of electrical power.

The anemometer-vane alone weighs 180g. The mounting plate and bracket weigh 160g.

The HR II wind transducer / vane anemometer is designed to operate within a temperature range of -10°C to +50°C.

The air temperature measurement by the sensor operates within a range of -10°C to +50°C.

The NKE HR II wind transducer / vane anemometer has an IP67 waterproof rating, ensuring resistance to humid marine environments.

Yes, the HR II wind transducer / vane anemometer integrates a 3D attitude sensor (IMU) for three-dimensional calculations at the masthead, which optimizes wind data accuracy while underway.

The HR II wind transducer / vane anemometer communicates via NMEA0183-HS protocols at 38400 baud (with MWV sentences at 50Hz for wind data and XDR at 1Hz for air temperature) and NKE Topline.

Yes, it is compatible with existing NKE navigation systems thanks to its NKE Topline communication protocol.

Yes, thanks to its NMEA 0183-HS protocol, it can be seamlessly integrated with other NMEA-compatible equipment.

Yes, the sensor’s power supply ranges from 10 to 16 VDC, making it compatible with a standard 12 VDC power supply.

The sensor must be mounted as high and as far as possible from any equipment that could mask or disrupt airflow to ensure accurate measurements.

The system allows for stored correction of the wind transducer's mechanical offset. To do this, ensure the anemometer-vane shaft is aligned with the boat's axis and calibrate the transducer by adjusting the offset value based on the average apparent wind angles on starboard and port tacks.

If the apparent wind speed reads 0.0 and the air temperature channel shows "Error", the anemometer-vane sensor may be disconnected or damaged. Check the cable and connection to the display unit.

If the apparent wind speed reads 0.0 regardless of actual wind speed, check that the calibration coefficient is not 0.0 and that the anemometer is not jammed.

If the apparent wind angle is inconsistent, check that the wind transducer vane is aligned with the boat's axis and perform a vane calibration to correct the offset.
