    The Hottest Static Wind Sensor Around

    The static hotwire air flow meters, also known as Thermal Anemometer, is specially designed for extreme environmental conditions including very cold-climates. With no movable elements, it can withstand winds of up to  0...100 m/s and measure wind speeds of up to 65 m/s. Extremely robust and compact sensor has a high-quality, pollutant-resistant housing made of anodised aluminium.

    Static Wind Sensor Features

    • no movable measuring elements
    • measures wind direction and wind speed
    • standard RS 422 interface with ESD protection
    • ASCII data protocol according to NMEA 0183
    • simple, space-saving assembly
    • analogue output 4...20 mA for wind speed and wind direction
    • power supply 18...32 VDC with integrated overvoltage protection
    • integrated sensor head heating and heating ring in the base prevent a build-up of ice and snow at the sensor
