The Thies 2D Ultrasonic Anemometer S82800H Overhead is a precision 2-axis ultrasonic wind sensor specifically configured for upside-down installation and winter operation. It measures horizontal wind speed, wind direction and acoustic virtual temperature using ultrasonic propagation-time measurement, allowing accurate and inertia-free detection of rapidly changing wind conditions without moving components. The S82800H incorporates heating of the sensor arms and ultrasonic converters, RS485/RS422 digital interfaces, configurable analogue outputs and an internal measurement rate of up to 400 measurements per second. Its overhead mechanical configuration provides an alternative installation arrangement for specialised meteorological and cold-climate monitoring sites.
Key Features
- Dedicated overhead installation configuration
- Designed for upside-down winter operation
- IEC 61400-12-1:2017 classified
- 2-axis ultrasonic measurement
- Wind speed measurement
- Wind direction measurement
- Acoustic virtual-temperature measurement
- 0–75 m/s wind-speed range
- ±0.1 m/s low-speed accuracy
- ±2% high-speed accuracy
- ±1° wind-direction accuracy
- RS485 / RS422 communication
- Configurable analogue output
- Heated arms and ultrasonic converters
- IP67 protection
The defining feature is the overhead mounting orientation. Thies specifically designed S82800H for upside-down winter installation while retaining heated sensor arms and ultrasonic converters, giving system designers an additional mounting option where a conventional upright installation is unsuitable.
