Wind Sensor

Wind velocity indicators are used for detecting and in connection with the appropriate indicator, monitoring a maximum wind velocity. They are used mainly in safety and monitoring systems of cranes and excavators. Two models are available. One with pendulum orientation, especially suited for the attachment on jibs of mobile cranes, and a common one, pedestal mounted or mounted on a vertical post. The output signal, being proportional to the wind velocity is taken either from a built-in tachometer generator in form of a voltage or from an optoelectronic impulse transmitter with frequency-current converter in form of a current signal in two-wire technique. For applications in the temperature range down to minus 50 °C there is optionally available for both models a mounting arrangement for a temperature controlled heating device. Cross arms feed-through sleeve and crown are splash-proof, degree of protection IP 65.
