Key Technical Advantages
Designed for precision and durability, the transducer features an integrated transceiver design with optimized impedance matching. This ensures high sensitivity and a superior signal-to-noise ratio, critical for detecting low-velocity air movement and rapid wind gusts.
High-Frequency Precision: The 200kHz resonance frequency allows for shorter wavelengths, significantly improving the resolution of phase-shift calculations in wind speed algorithms.
Environmental Robustness: Housed in a hermetically sealed, chemically resistant enclosure, the sensor remains stable in extreme conditions ranging from -40°C to +70°C. It is immune to corrosion, dust, and icing, making it ideal for marine and offshore applications.
Acoustic Performance: The probe delivers a wide bandwidth with minimal ringing (afterglow), enabling faster sampling rates and more accurate measurement of wind vectors.
Applications
This ultrasonic transducer is the preferred OEM solution for developing:
Meteorological Stations: Automatic Weather Stations (AWS) requiring WMO-standard accuracy.
Renewable Energy: Wind turbine control systems for pitch and yaw optimization.
HVAC & Air Quality: Precision airflow monitoring in tunnels and smart buildings.
Marine Navigation: Solid-state wind sensors for ships and buoys.
