1,Introduction: The wind speed monitoring device is mainly used for measurement on speed of wind in engineering machinery (crane, crawler crane, gantry crane, tower crane), railway, port, wharf, power plant, meteorology, ropeway, environment, greenhouse, aquaculture, air conditioning, energy monitoring, agriculture, health care, clean space areas etc. This product is a kind of monitoring device designed according to industry standard. It has series of advantages, such as convenient installation, simple debugging, reliable work, high measurement precision etc. The main function is monitoring of the current wind speed in real time. When the wind speed reaches a certain scale, it appears sound and light alarm signals on the instrument of product. 2, The main technical indicators: 1) Instrument performance indicators The integrated error does not exceed ± 5%; Rated power: 5W; Operating voltage: AC220V, 50 ~ 60HZ (allowable voltage fluctuation range + 10% ~ -15%); Host protection grade: IP64; Relay contact form: NC, capacity 6A / 250VAC; Environment: -20 ºC ~ +65 ºC, 90% RH; Instrument function: Display current wind speed in real time Display indicating wind speed in real time (optional function). 2)Performance indicators of wind speed sensor Sensor protection grade: IP65; Type of the current output: 4-20Ma; Power: DC5-24V; Wind speed resolution precision: 0.1m/s; Start wind power: 0.4-0.8m/s weight less than 0.5Kg. 3, The main working principle: The wind speed monitoring device is mainly monitor scale and direction of wind. The wind direction sensor displays the current wind direction in real time. The direction of Wind direction sensor refers to is the direction of the wind. The 8 blue LED on instrument respectively represent different directions, such as the East, South, West and north direction etc. When the wind direction sensor pointed to corresponding LED light of the direction instrument, it indicates the right direction. Calibration for wind direction sensor: Have the arrow of wind direction sensor to the north direction when Power-on. Press the button for 3-5 seconds when the wind direction sensor is stable and it calibrates successfully.
The wind speed sensor displays the current wind speed level in real time. When the wind level reaches the warning point (5.4 m / s <wind speed <10.7 m / s) set by the instrument, the dashboard flashes and the current wind level is displayed. The yellow LED light is on and the buzzer tweets intermittently. When the wind level reaches the alarm point (wind speed> 10.7 m / s), the digital tube of instrument flashes and displays the current wind level, the red light and yellow light is on, the buzzer is always tweeting, and the relay is disconnected to control the external device.
