Wind sensor FSG

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.

The Indicator
contains an electronic LED circular bar graph display with a maximum limiting position contact, adjustable from outside.

The measuring value is represented in form of a green bar graph display. By a read-out potentiometer on the front side the limit value mark can be preselected within the chain of diodes. If the green shining actual value display passes over the red shining mark of the preselected limiting value, the colour of the actual value display changes to red. At the same time, the limit value relay switches over and signalises the passing over the maximum value by switching over a floating contact.

The switchgear
is an electronic comparator, constructed as a plastic casing, surface-type, suitable for screwing or rail mount according to DIN 46 277.

For the application range of crane and excavator measuring technique the delivery program contains among other things even additional measuring components, for instance:

• live ring and rope winch shaft encoders
• rope length and cable drum transmitters
• uniaxial and biaxial tilt angle transmitters
• X/Y-control transmitters
• pedal actuated control transmitters

Up to a maximum of four limit indicators/comparators can be integrated in one casing unit, their switching points can be adjusted separately by means of trimming potentiometers between 0 and 100% of the input quantity. The output signals are available via floating relay contacts
