YF5 Wind Speed Alarm/Tower Crane Three Cup Wind Speed Sensor

YF5 Wind Speed Alarm/Tower Crane Three Cup Wind Speed SensorThe YF5 wind speed alarm uses a photoelectric three cup wind speed sensor and microcontroller technology to detect instantaneous wind speed(Three second average)）Perform real-time measurements and automatically compare real-time values with pre-set pre alarm and warning values. If the measured value exceeds the above set value, the instrument will give a pre alarm and an alarm through sound and light signals. When the pre alarm and alarm are generated, the instrument can also control external equipment through their respective sets of conversion relay contacts.

YF5 Wind Speed Alarm/Tower Crane Three Cup Wind Speed SensorBasic principle:

The instrument uses a three cup rotating frame wind speed sensor. A cover plate is installed on the rotating shaft of the rotating frame, and a photoelectric switch and cover plate are used to convert the rotational speed of the rotating frame into a pulse frequency signal, which is output to the alarm host. The host shapes the pulse sent by the wind speed sensor and sends it to the microcontroller for counting/The input port of the timer, each time the hostMeasure the frequency of the wind speed signal once per second, and then measure the frequency per secondCalculated using a 3-second sliding average processing3-second average wind speed. Every second, the measured sliding average wind speed is compared with the wind speed forecast alarm value and alarm value. If the measured value is greater than the forecast alarm value or alarm value, the microcontroller will activate the corresponding forecast alarm relay and alarm relay. Their set of switching contacts can be used to control external devices and also provide sound and light alarm signals.
twoBasic purpose:The FYF5 wind speed alarm has a simple structure and high degree of automation, which can continuously monitor instantaneous wind speed. It is suitable for departments that are very concerned about wind speed, such as airports, ports, tower cranes, and fire prevention, to conduct real-time monitoring and alarm of wind speed.
