Featuring an anodized aluminum body and Luran cups, it operates without power consumption and offers a frequency output (reed relay) for seamless integration with LSI LASTEM data loggers and third-party systems. Ideal for wind farms and long-term environmental monitoring.
Overview
The DNA202.1 compact anemometer delivers reliable wind speed measurements in extreme conditions. Featuring an anodized aluminum body and Luran cups, it operates without power consumption and offers a frequency output (reed relay) for seamless integration with LSI LASTEM data loggers and third-party systems. Ideal for wind farms and long-term environmental monitoring.
Precision Wind Monitoring for Demanding Environments
Engineered for resilience, the DNA202.1 withstands severe weather and winds up to 75 m/s. Its anodized aluminum housing and UV-resistant Luran cups ensure corrosion-free operation from -35°C to 70°C. Perfect for wind energy assessments, meteorological studies, and remote sites requiring zero maintenance.
Plug-and-Play Integration
With a pulse output (2.6–2.8 Hz per m/s), this anemometer pairs effortlessly with LSI LASTEM’s E-Log and Alpha-Log data loggers. The IP66-rated 7-pin connector supports DWASxxA cables (sold separately), while optional STB/MSB accessories convert signals to 4–20 mA or Modbus-RTU outputs.
Key Advantages
- Zero power consumption—ideal for solar/wind-powered sites
- ISO17025-accredited factory calibration for traceable accuracy
- Reed-relay frequency output for broad compatibility
- IP66 protection against dust and water ingress
- Mounts on standard 48–50 mm masts (DYA046 coupling bar optional)

Usage Guidelines
Installation & Maintenance
Mount vertically on a stable mast using the 7-pin IP65 connector. Avoid icing conditions beyond operational limits. For signal conversion, use STB (DEA420.1) or MSB (MDMMA1010.1) accessories. Calibration certificates (ISO17025/ISO9001) available upon request.
Safety Notes
Do not exceed 75 m/s wind speeds. Use only compatible DWASxxA-series cables. In subzero environments, ensure ice does not accumulate on cups.
