| What Matters Most | Typical Ultrasonic Wind Sensor | WindUltra |
|---|---|---|
| Wind speed range | Commonly up to 40-60 m/s | Accurate measurement up to 75 m/s for extreme wind environments |
| Operating temperature | Typically -20°C to +60°C | Full performance from -40°C to +70°C |
| Cold-weather reliability | May require optional heating or reduced performance in icing conditions | Integrated heating option maintains accuracy in freezing and icing conditions |
| Ingress protection | Common IP65-IP67 | IP69K dust, water jet and impact protection with additional IP66/IP68 robustness |
| Weight & mounting | Wider variation; often bulkier housings | Ultra-compact, low-profile, lightweight (~270g) for easy installation in tight or mobile settings |
| Maintenance | Solid-state but may still require periodic checks or cleaning | Zero moving parts, low maintenance, long operational life |
| Protocol flexibility | Often one or two outputs | Multiple outputs (RS-485, MODBUS, NMEA, SDI-12) standard |
| Application range | Suitable for general wind sensing | Purpose-built for extreme-environment monitoring including offshore, deserts, mountains, UAVs, smart infrastructure and industrial sites |

Reliable operation in the most aggressive conditions including dust and sand.
High data accuracy is required at all times to report and manage local conditions.
Continuous wind measurement is essential for the operation and maintenance of offshore wind farms. (MEASNET certification optional).
Unmanned vehicles need high performance in a compact, tough, low maintenance and low energy format.
WindUltra takes wind measurement to a new level of accuracy and robustness in a compact unit.
Building on the highly trusted performance of Gill’s market leading range of WindSonic 2-axis ultrasonic anemometers, WindUltra demonstrates superior performance in aggressive environments (IP69k), with innovative mounting options for superfast installation.
