The 50.5 Solid State Wind Sensor is a continuation of the development work started with NOAA on sonic wind sensors over 25 years ago. This sensor design contains the same wind distortion algorithm and factoring that has been proven and accepted in applications around the world.

No other sensor technology has the history of time-proven field performance as the 50.5 sensor.

  • No moving parts
  • Digital and analog outputs
  • Built-in sensor emulation
  • 16-point wind tunnel calibration with each sensor
  • Data output is field-set to user requirements
  • Optional heating unit allows continuous operation in ice and snow
  • Low maintenance
