Ultrasonic Anemometer Thies 2D – Heating in Arms
IEC-classified 2D ultrasonic anemometer for maintenance-free wind speed, direction and virtual-temperature measurement, featuring high-speed acquisition, digital/analogue outputs and heated sensor arms.
Typical Applications
- Wind resource assessment
- Wind turbine power-performance measurement
- Wind-farm monitoring
- Meteorological stations
- Wind measurement in cold climates
- Gust and peak-wind measurement
- Met-mast installations
- Environmental monitoring
- Research stations
- Professional wind measurement campaigns
The Thies 2D Ultrasonic Anemometer S82100H is a high-precision, maintenance-free 2-axis ultrasonic wind sensor designed to measure horizontal wind speed, wind direction and acoustic virtual temperature without moving mechanical components. The sensor determines airflow by measuring differences in ultrasonic sound propagation time across two orthogonal measurement paths, enabling inertia-free response to gusts and peak wind speeds. Classified according to IEC 61400-12-1:2017, the S82100H combines digital RS485/RS422 communication, configurable analogue outputs, high-speed internal measurement and heating of the sensor arms for reliable wind-energy and meteorological operation in cold conditions.
Key Features
- 2-axis ultrasonic wind measurement
- IEC 61400-12-1:2017 classified
- Measures wind speed
- Measures wind direction
- Measures acoustic virtual temperature
- 0–75 m/s wind-speed range
- 0.01 m/s starting threshold
- ±0.1 m/s accuracy up to 5 m/s
- ±2% accuracy above 5 m/s
- ±1° wind-direction accuracy
- RS485 / RS422 digital interface
- Configurable analogue outputs
- Up to 400 internal measurements per second
- Heated supporting arms
- IP67 environmental protection
Unlike a cup anemometer, the S82100H has no rotor inertia or moving bearings. This makes it particularly valuable where accurate capture of short-duration gusts and peak wind events is important, while also reducing the mechanical maintenance associated with conventional wind sensors.
