The mining wind speed and direction sensor is a measuring instrument that uses the time difference of ultrasonic waves propagating in the air to measure wind speed. It utilizes the time difference that occurs when ultrasonic waves travel the same distance with and against the flow of the fluid. This time difference is related to the flow velocity of the fluid being measured, allowing the fluid velocity to be derived from the measured time difference. The host device collects ultrasonic signals through two ultrasonic probes, and after data analysis and calculation, the specific wind speed is obtained. The sensor is equipped with a drive mechanism to enable full-section wind speed scanning measurement. The ultrasonic probes can be fitted with a cleaner, driven by an intrinsically safe motor. When wind speed data fluctuations exceed the limit, the host sends a cleaning command, the cleaner performs the cleaning, and stops once the wind speed data stabilizes. The cleaning can be completed within 5 minutes, and scheduled operation can also be set.
