HD51.3D 2-axis ultrasonic anemometer for harsh environments

Product Description

The HD51.3D Ultrasonic Anemometer is designed for precise measurement of wind speed, direction, and U-V components, with reliable performance even in demanding environments.

Using ultrasonic technology with no moving parts, it ensures long-term stability with minimal maintenance. The sensor supports high wind speeds (up to 100 m/s for selected models), making it suitable for applications such as wind farms, infrastructure monitoring, and marine environments.

With flexible configuration options, the HD51.3D can also integrate additional measurements such as temperature, humidity, pressure, and solar radiation, providing a compact and adaptable environmental monitoring solution.

Key Features:

• 2-axis ultrasonic wind measurement (speed, direction, U-V components)
• Supports high wind speeds up to 100 m/s (model dependent)
• No moving parts → low maintenance and long-term reliability
• Configurable wind gust and averaging calculations
• Optional sensors: temperature, humidity, pressure, solar radiation
• Built-in compass and tilt sensor for accurate installation
• Outputs: RS232, RS485, RS422, Modbus RTU, analog outputs
• High resistance to corrosion, vibration, and harsh environments
• Optional heating system for operation in snow and icing conditions
• Suitable for wind energy, marine, infrastructure, and environmental monitoring

HD51.3D is a 2-axis ultrasonic anemometer suitable for harsh environments (e.g. corrosive environment, strong vibration, or high wind speed). The anemometer meets the requirements of MIL-STD-810G Method 509.6 (salt spray corrosion test) and is suitable for deployment in coastal areas.

HD51.3D can be integrated with other environmental sensors. For example, HD51.3DP147 is similar to HD52.3DP147, with temperature, humidity, barometric pressure, and solar irradiance measuring capabilities.

The outputs by HD51.3D are also very similar to HD52.3D.
