Thies First Class POT Wind Vane
High-precision electronic POT wind direction sensor with classic potentiometer-compatible wiring and wear-free electronic sensing, available in standard and heated configurations.
Typical Applications
- Wind resource assessment
- Wind-farm monitoring
- Wind turbine site assessment
- Meteorological stations
- Existing potentiometric measurement systems
- Met-mast installations
- Wind direction monitoring
- Environmental stations
- Wind-energy research
- Cold-climate installations with S21230H
The Thies First Class POT Wind Vane is a robust, high-precision analogue wind direction transmitter for wind-resource assessment, meteorological stations and wind-energy monitoring. Instead of relying on a mechanically stressed conventional potentiometer, its electronics emulate potentiometer behaviour while avoiding mechanical wear and ageing, while retaining wiring compatibility with classic potentiometric wind vanes and Ammonit data-acquisition systems. The First Class platform provides full 0–360° wind direction measurement, low starting threshold, short dynamic response and rugged outdoor construction, while the S21230H configuration adds electronically regulated heating for cold and icing-prone installations.
Key Features
- Active electronic POT measurement
- 0–360° wind direction range
- Approximately ±1° precision for the active First Class POT architecture
- 0.35° resolution
- Analogue output
- Potentiometer-compatible wiring
- No mechanical potentiometer wear
- Low starting threshold
- Short 1.8 m distance constant
- Damping ratio greater than 0.3
- Aluminium construction
- IP55 environmental protection
- -50°C to +80°C operating range
- Optional electronically regulated heating
- 24 V AC/DC heating system
The POT version is useful when an existing station is already wired for traditional potentiometric wind vanes. Its electronic architecture maintains compatible analogue behaviour while removing the mechanical contact wear normally associated with a physical potentiometer.
