Selfpowered wind speed sensor with no external power required Generates a voltage signal directly from wind rotation No power source needed to operate the sensor How it works When horizontal wind interacts with the wind cup, its special structure causes rotation in a specific direction The builtin sensor converts this rotation into a voltage signal The voltage is proportional to the rotation speed and is displayed by the specially customized pointer instrument Benefits and readings Direct, analog reading of winddriven rotation without the need for batteries or power supply Simple connection to the customized pointer instrument for realtime display Maintenance design with no external wiring for power Key attributes Function: winddriven voltage generation proportional to rotation speed; display via pointer instrument Compatibility: designed to connect to and be read by the specially customized meter/pointer instrument Size: dimensions vary by model; refer to specific product datasheet for exact size Material: construction details vary by model; refer to specific model specifications Performance: selfpowered; voltage signal corresponds to rotation speed under horizontal wind conditions Specifications and model notes The sensor's size and materials are modeldependent; consult the product datasheet for exact figures Reading requires the specified customized pointer instrument to interpret the voltage output Use scenarios Remote outdoor installation with limited or no power supply, where continuous wind monitoring is needed Greenhouse or ventilation monitoring to assess wind flow and its effect on internal conditions Educational demonstrations or field experiments to illustrate windinduced voltage generation and analog readouts Additional guidance Ensure wind direction is predominantly horizontal for accurate operation Use only with the designated pointer instrument to view the voltage signal For installation and integration details, refer to modelspecific documentation
