This  2-axis  ultrasonic  wind  sensor offers  maintenance free wind speed and direction monitoring for true  ‘fit and forget’ wind sensing. It  is  a  genuine  low  cost  alternative  to  conventional  cup  and  vane  or  propeller  wind  sensors,  with  all  of  the advantages  of  solid-state  ultrasonic  technology.  With  no  moving  parts  to  jam,  break  or  wear  out,  this  ultrasonic wind  sensor  is  ideal  for  use  in  harsh  weather  conditions  and eliminates  the  need  for  expensive  on-site maintenance. Wind  speed  and  direction data is  output via  one  serial  or  two  analogue
channels.  To  confirm  correct  operation, serial outputs are transmitted together with an instrumentation status code. Low power consumption, no moving parts and the corrosion free exterior make the WindSonic ™M ideal for a wide range  of  wind  monitoring  applications.   

Particularly  suited  to  marine  &  offshore  (wind  farms, ships,  data  buoys) and land based installations, especially in remote locations where access is difficult and power availability limited. The serial data output is ideal for interfacing with a WS-15A Display Unit or for data logging to a  SpaceLogger®WindLogger.
