The ultrasonic wind sensor u[sonic] was specially designed for extreme environmental conditions. It comes without any moving measuring elements and is ideal for high wind speeds. The extreme robust, compact sensor has a high-quality, pollutant-resistant housing made of hard anodized aluminium and stainless steel.Features– Measure three parameters in one device: wind direction, wind speed and virtual temperature
– Without movable measuring elements
– No abrasion, low maintenance
– Standard RS 485 interface with ESD protection
– ASCII data protocol according to NMEA 0183
– Power supply (without heating) 6…60 VDC or 12…42 VAC
– Power supply (with heating) 24 V AC/DC +/- 20 %
– Simple, space-saving assembly on 50 mm standard pipe
– Analogue output 0…20 mA, 4…20 mA, 0…5 V or 0…10 V for wind speed and wind direction
– Heating power 60 W, 120 W, 240 W (standard)Applications– Under icing conditions- Onshore and offshore applications- Wind turbines- Railway line monitoring- Traffic meteorology- Chemical and industrial facilities- Power plants, sewage plants and landfills
