Ultrasonic Anemometer Thies 3D – Heating for Extreme Icing Conditions
Extreme-icing 3D ultrasonic anemometer with whole-sensor heating, providing precision X/Y/Z wind vectors, direction and acoustic virtual-temperature measurements for severe winter environments.
Typical Applications
- Extreme cold-climate wind assessment
- Severe icing environments
- High-altitude meteorological stations

- Three-dimensional turbulence studies
- Wind turbine research
- Atmospheric boundary-layer research
- Gust and extreme-event monitoring

The Thies 3D Ultrasonic Anemometer S83300H is an advanced three-dimensional ultrasonic wind sensor engineered for professional measurements in extreme icing and severe winter environments. It measures horizontal and vertical wind velocity, wind direction and acoustic virtual temperature using three orthogonal ultrasonic measurement paths formed by six acoustic transducers.
The S83300H provides inertia-free measurements across the X, Y and Z axes, making it suitable for turbulence analysis, gust measurement, atmospheric research and advanced wind-energy assessments. Digital signal processing supports configurable averaging, standard deviation, covariance and other statistical functions. Unlike the standard heated S83100H, the S83300H employs extra-strong heating across the sensor arms, ultrasonic converters and housing, helping maintain measurement availability during severe icing conditions.
Key Features
- Extreme-icing 3D ultrasonic wind sensor
- IEC 61400-12-1:2017 classified
- Measures X, Y and Z wind vectors
- Horizontal and vertical wind measurement
- Acoustic virtual-temperature measurement
- 0–85 m/s specified wind-speed range
- Measurement output up to 99.99 m/s
- 0.01 m/s starting threshold
- RS485 / RS422 digital interfaces
- Configurable analogue outputs
- Up to five analogue inputs
- 32-bit DSP processing
- Up to 285 measurement sequences per second
- Extra-strong whole-sensor heating
- Heated sensor housing for severe icing conditions
The housing heater is the key reason to choose S83300H instead of S83100H. In severe icing environments, keeping only the acoustic transducers clear may not be enough; S83300H additionally heats the housing so that ice accumulation on the broader sensor structure is less likely to interfere with long-term measurement availability.
