Description

We LEFOO offer a series of wind speed transmitters with high-temperature and corrosion-resistant housing. These wind measuring devices, based on the heat dissipation or Pitot principle, require minimal airflow to maintain stable and reliable performance in harsh environments. Compared to conventional sensors, such as an air velocity transducer or a standard air flow sensor, they offer better stability, faster and accurate airflow measurement, a wide range ratio, and high accuracy through internal microcontroller calibration and digital compensation. Zero drift-free and long-term stability make them cost-effective. Additionally, they can withstand instantaneous high wind speed and pressure.
