Product Summary
The FT702LM is a solid-state wind sensor which uses a patented Acoustic Resonance airflow sensing technique to measure accurately both wind speed and direction.
The acoustic resonance sensing technique coupled with state-of-the-art signal processing gives the anemometer a wind speed range of 0 to 50m/s with a resolution of 0.1m/s.
Comprehensive measurement data (up to 5 readings per second) is available via a serial RS422 interface featuring full-duplex operation. The highly compact and symmetrical arrangement of the acoustic resonant cavity results in a physically small (50mm x 78mm), lightweight (250g) and robust anemometer.
When mounted on a suitable enclosure the FT702LM is environmentally sealed to IP66 allowing it to be used in a wide range of demanding applications. The FT702LM is ideal for battery powered applications and is able to operate at supply voltages as low as 3.5V (@ 12mA typical current drain).
The FT702LM is available with an optional electronic compass module so that the wind direction output can be obtained relative either to magnetic North or, by using the declination angle function, to true North.
There is an integral heater to prevent icing. It can either be switched on and off as required or it can be automatically controlled by the sensor.
