Anemometr-wiatromierz HR II (bez kabla)

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 standalone wind transducer/vane anemometer 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 is performed within a range of -10°C to +50°C.

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

Yes, the HR II wind transducer 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 frames 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 NMEA0183-HS protocol, it can be seamlessly integrated with other NMEA-compatible equipment.

Yes, the sensor's power supply is between 10 and 16VDC, making it compatible with standard 12VDC power.

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 mechanical offset of the wind transducer. To do this, ensure the anemometer-vane shaft is aligned with the boat's axis and perform a vane calibration 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 faulty. Check the cable and connection to the display unit.

If the apparent wind speed reads 0.0 regardless of wind speed, you must check that the calibration coefficient is not 0.0 and that the anemometer is not obstructed.

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