Display unit and wind speed sensor with pre-alarm and alarm. Ideal in conjunction with the Anemo4403 sensor.

Adaptable to a wide range of anemometer sensors.

Pre-alarm (ALARM1) and Alarm (ALARM2).

Designed for panel mounting, such as in electrical cabinets. Especially designed for construction cranes. For installation on DIN RAIL see model WM44-P.



  • 3-digit wind read out.
  • 2 alarm indicator LEDs enabled “AL1 and AL2”.
  • Wind speed in km/h and mph.
  • Programming in kilometres/hour ( km/h) or in miles/hour (mph).
  • P01 You can switch between km/h and mph at any time by pressing “Select”, a user accessible button.


The alarm is triggered when the programmed value is reached or surpassed and it has includes a delay to prevent false alarms due to short gusts. The alarm is disabled when the wind speed drops below the programmed value and provided this condition persists for a minimum period. When ALARM 2 is enabled ALARM 1 is disabled. When ALARM 2 is enabled, the reading on the display will blink, as a warning.

Alarms can be programmed for the following: trigger values, intermittent or continuous, interlocked (only alarm2). The alarm outputs are through voltage-free relay contacts. Choice between: on contact open or on contact close. Possibility of alarm interlock 2. With the alarm disabled when the unit’s power supply is cut off.


Suitable for a wide range of sensors: Power supply sensors: 20 V or 10 VDC, from the unit itself. types : 3-wire and 2-wire (see examples on faceplate connections from the unit itself). We RECOMMEND pairing the unit with our Anemo4403 model.


In addition to user-programmed another, alternative programming can be saved in memory. This can be retrieved any time by going to the program step. P00 option 4.
