| description | In order to monitor gas countercurrent leaded by coal mine gas outburst accidence, a mine-used ultrasonic transducer of wind speed and direction was designed based on principle of ultrasonic time difference method. The relationship between the wind speed and direction and the time difference of ultrasonic transmitting and receiving is applied to operate and obtain the wind direction and speed. The testing results show that the transducer has strong stability and high measurement accuracy, wind speed measurement range is 0.4-15 m/s, its error is no more than 0.3 m/s and wind direction measurement range is 0-360 degree, error is no more than three degree. |
