Description

This durable 2-axis ultrasonic anemometer facilitates the measurements of wind speed and direction and the U-V Cartesian components of wind speed. Operating according to the ultrasonic principle, it is unaffected by inertia and can therefore detect extremely low wind speeds to a high degree of accuracy.

The sensor requires a 10-30 VDC power supply, making it particularly suitable for remote applications. As it contains no moving parts, this ultrasonic anemometer can be left for up to two years without the need for maintenance or re-calibration. The sensor has a very small power draw, making it ideal for remote solar-powered or wind-powered systems.

This lightweight sensor can be fitted to any 40 mm diameter pole/mast. The inbuilt compass makes installation and alignment quick and easy. Optionally, it can be fitted with a heater to prevent the accumulation of ice and snow in low temperatures.

The sensor’s analogue outputs are 0-1 VDC, 0-5 VDC or 4-20 mA. The serial outputs are RS232 and RS485 following communication protocols SDI-12, MODBUS or NMEA.

This instrument can also be supplied with integrated sensors to measure temperature, relative humidity, barometric pressure and solar radiation (please state if this functionality is required when requesting a quotation).
