4310 Precise ultrasonic anemometer
- Highly accurate ultrasonic anemometer with RS485 output compatible with FIEDLER recording units
- Robust design of the device without moving parts
- High measurement accuracy given by optimized aerodynamic design of ultrasonic sensors
- Supply voltage in a wide range of 9 to 36 VDC
- Variant design with outputs RS422, 0..10V, 4-20 mA, CAN, ...
Optimized design
The design of the mechanical design of the ultrasonic anemometer was also made with the help of SW simulation. As a result, turbulence occurring on ultrasonic transducers was minimized.
Reducing turbulence to a minimum resulted in a maximum increase in the accuracy of wind speed and direction measurements.
Application
- Professional weather stations
- Intelligent building management (heating, clinization, ventilation, ...)
- Industrial buildings and security of building structures
- Science and research - environmental monitoring
