MeteoWind 2
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
