Cup thermo-anemometer IceFree3

The electrically heated NRG IceFree3 Anemometer's simple, robust design provides a proven and reliable solution in icing environments. Features * Made of cast aluminum with black anodized finish and heat-resistant paint * Efficiently transfers heat from encapsulated, self-regulating heaters * Easily mounts to a 27 mm (1.05") diameter mounting pipe * Powered by 24V AC or DC * Compatible with a wide range of remote site equipment Performance * Signal output is a variable amplitude sine wave, where frequency is proportional to wind speed * Patented off-axis correction minimizes errors in measuring up-slope or down-slope winds * Operating temperature range: -40 °C to 60 °C (-40 °F to 140 °F)
