Overview
The WS200-J is an all-in-one weather sensor measuring wind speed and direction, with WMO-compliant gust reporting. A drop-in replacement for the Lufft WS200, the WS200-J is an updated model built on the same trusted Lufft platform, reporting data every 5 seconds instead of every minute, and with integrated self-diagnostics. Built for Wind Energy, Meteorological Observation and Research Networks that need reliable wind data without paying for additional parameters. Now you can measure more, maintain less with the WS200-J.
Benefits
Performance & Tender- Readiness
Delivers ultrasonic wind speed, direction and an integrated compass measurements with exceptionally low power consumption. Implemented WMO compliant wind gust calculation. Ideal for installations in 10m height as well in remote and solar-powered deployments.
Wind speed is reported up to 75 m/s and as all our measured parameters 100% tested in our certified calibration process. Each WS-J comes with a FAT certificate.
Low Lifecycle Cost by Design
Ultrasonic sensing eliminates moving parts, reducing maintenance requirements and supporting dependable long-term performance.Reduced Risk, Improved Self-Diagnostics
One Platform Across Networks
