Your present location:HomeproductsWind Speed Direction - RK100-02 Wind Speed Sensor
  • Product Name: RK100-02 Wind Speed Sensor

The RK100-02 Wind Speed Sensor uses a sensitive 3-cup anemometer designed to measure wind speed and wind run. The cups are made of carbon fiber material, with high intensity and low starting threshold. The signal processing units are built in the housing shell. It can be widely used in meteorology, marine, environmental monitoring, airport, harbor, laboratory, industrial and agricultural areas.

FEATURES

  * Low starting threshold
  * Overall carbon fiber material
  * Strong corrosion resistant ability
  * Light structure
  * Various output signals optional
  * Easy Installation

APPLICATIONS

  * Weather monitoring stations
  * Safety monitoring of high altitude equipment
  * Ports
  * Solar and wind power generation
  * Mobile weather monitoring vehicles
  * Marine vessels
  * Remote airports & helipads
  * Road & rail tunnels n
