Overview

YF6 wind speed alarm device 4-20mA with 20 meter cable YF6 wind speed alarm device applies photoelectric three cup wind speed sensor and single-chip technology to measure instantaneous wind speed (three second average value) in real time, and automatically compares the real-time value with the pre-set forecast alarm value and alarm value. 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. The instrument can also output a set of analog signals (0-10V voltage or 4-20mA current)

Product Details

YF6 wind speed alarm 4-20mA with 20 meter cableThe YF6 wind speed alarm uses a photoelectric three cup wind speed sensor and microcontroller technology to measure the instantaneous wind speed (three second average) in real time, and automatically compares the real-time value with the pre-set forecast alarm value and alarm value. 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. The instrument can also output a set of analog signals (0-10V voltage or 4-20mA current).

YF6 wind speed alarm 4-20mA with 20 meter cable：

1、 Basic 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 measures the frequency of the wind speed signal every 1 second, and then performs a 3-second sliding average on the frequency per second to calculate the 3-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 YF6 wind speed alarm has a simple structure and high degree of automation, and 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 use for real-time monitoring and alarm of wind speed.
