Wind speed & wind direction

Anemometer with a wind vane. Exceeds WMO and MEASNET Class 1 accuracy standards for meteorology & wind resource assessment. Very low 4mA combined power consumption and integrated triple layer lightning & surge protection for reliable operation. Protected oversize bearings with high dirt and weather resistance proven to provide long-term measurement stability & reliability in dirty & dusty environments.

Serviceable bearing & cups with high dirt resistance

  • Serviceability of rotor bearing, anemometer cups and wind vane
  • Special double-arm reinforced cup design with over-size bearings for robustness.
  • Highest level of 3 stage lightning, EMC, Surge & ESD protection
  • Industry standard RS-485 output
  • Simple & robust MODBUS RTU and ASCII communication protocol is user selectable
  • Long-term tested dirt resistance in highly dusty environments with salt-spray
  • All models feature a weather proof locking bayonet connector

Dual arm reinforced cup design for all weather reliability

  • WMO & MEASNET conforming wind speed and direction.
  • 10Hz sampling rate to accurately capture wind gusts.
  • Fast response and minimal over-speeding for accurate
  • wind gust measurement.
  • Robust two arm reinforced rotor cup design
  • Special flat elliptical cups offer superb snow shedding
    with very good hail resistance
  • All-metal replaceable wind direction vane.
  • Strong all-metal anodized-aluminum body

Heated anemometer with wind vane 20 Watts of heat for all weather reliability

  • Built in dual heater distributes heat where it is needed most.
  • Heater can be controlled manually from a data logger or automatically based on anemometer temperature or based on anemometer temperature and wind speed.
  • Safe operation from 5V up to a 24V DC power source.
  • Heater output of can be controlled by input voltage
  • 20W at 24V for high reliability all weather deicing
  • 5W at 12V with user selectable automatic or manual control for solar powered AWOS/AWS weather stations
  • Patented flat elliptic cup design offers superb winter snow
    shedding even without heating.
