Analog output speed and direction sensor FAR3

digital outputnon-contactcompact

The FAR3 is an ultrasonic wind sensor that measures wind speed and direction simultaneously, engineered for harsh environments in wind power, marine, meteorology and transport sectors. It combines a high-power heater and digital signal processing to maintain reliable measurements in freezing rain, blizzard, heavy rain, salt spray and high electromagnetic interference.

Key features

• Time-difference ultrasonic measurement method providing strong resistance to environmental interference.
• Built-in 240W high-power heater with integrated temperature sensor for automatic response to freezing rain, blizzard and low-temperature conditions.
• High-efficiency filtering algorithm with dedicated compensation technology for rain, fog and snow.
• Anodized magnesium-aluminum alloy housing offering durable corrosion resistance (NSS 720h).
• Lightweight, compact dimensions and full protection rating (IP67).

Product description and application

• FAR3 uses ultrasonic technology and advanced digital signal processing to simultaneously measure wind speed and direction. The robust heating system and filtering algorithms make it suitable for wind farms, marine vessels, meteorological stations, transport infrastructure and other industrial installations requiring continuous operation in severe weather and electromagnetic environments.
