  • Data update rate

    Up to 10Hz

  • Error handling

    When the sensor detects an invalid reading an error flag is included in the wind velocity output message (see user manual for further details)

  • Overspeed Warning

    The sensor has an optional overspeed warning scheme. This scheme is disabled by default but can be enabled at the factory if requested. With the scheme enabled, if the sensor detects a wind speed greater than 75m/s a character is set in the wind velocity output message (see user manual for further details).

1All specifications subject to change without notice. Specifications calculated with the default settings and filters enabled. Kmph and knots are only available when using NMEA 0183 mode.

2Refer to user manual for further details.

3A suitable PSU capable of providing up to 0.2A maximum is recommended. RS422 current load is dependent on topology and resistor values – RS422 in ‘always enabled’ mode may draw higher currents. Refer to the user manual for further details.

4 Requires user calibration, refer to the user manual for further details.
