Sensors for environmental monitoring wind, NESA

Systems for environmental monitoring and remote control

Biaxial heated ultrasonic anemometer (x,y)


Ultrasonic sensor for the measuring speed and wind direction with heating, capable of measuring the characteristics of the wind along two orthogonal axes X, Y on the horizontal plane and their cartesian result. Made of resin and aluminum anodized alloy; the heating of the transducers expands the standard range of operation and ensures measurements in adverse weather conditions. Linear, accurate and extremely reliable in all conditions, high dynamic response. Easy to interface with each data logger. The sensor is equipped with electrical protections and is available with various signal outputs.


  • Ultrasonic sensor for the measurement of wind on horizontal plane
  • No moving parts, low maintenance and service costs.
  • Integrated heating system for applications in cold climates
  • Heavy construction, suitable for continuous operation even in harsh environmental conditions
  • Typical range: up 0÷60m/s (speed), 0÷359 ° (direction)
  • Resolution: 0.01 m/s (speed), 1° (direction), temperature compensated
  • Accuracy ± 2% of reading
  • Low power consumption (~10W max with heater on)
  • Output signal: 4÷20mA, or RS485/Modbus
  • Operating conditions: -40 ÷ +80°C
  • Power supply: 10÷30Vdc
