Tunnel ultrasonic wind speed and direction detector: supports 24-hour uninterrupted monitoring, with fast data update frequency. [Model recommendation: TH-SQX1, IoT integrated device, customized service supported by Yunjing Tianhe] The tunnel ultrasonic wind speed and direction detector achieves 24-hour uninterrupted monitoring through ultrasonic time difference method or Doppler effect. The data update frequency can reach milliseconds (such as 0.5 seconds/time), and can capture subtle changes in wind speed and direction inside the tunnel in real time, providing key data support for ventilation management, fire warning, and emergency response. By shortening the interval of ultrasonic pulse transmission (such as once every 0.1 seconds) and combining it with a high-speed signal processor (sampling rate ≥ 1kHz), the high-frequency data update capability enables it to timely reflect sudden changes in airflow inside the tunnel (such as piston wind effect when vehicles pass through), providing a basis for dynamic control of the ventilation system. By measuring the time difference of ultrasonic propagation in the downwind and upwind directions, combined with a multi probe layout (usually two or four sets of ultrasonic transducers arranged in a cross pattern), the wind speed is accurately calculated and the wind direction is synthesized.

Product Overview:

The SQX1 tunnel wind speed and direction detector is a monitoring device tailored for tunnel environments. The detection probe is installed on the tunnel wall and uses ultrasonic time difference method to accurately measure wind speed and direction, providing wind speed and direction detection values for the tunnel control room. The data from the tunnel wind speed and direction detector supports the design and operation decisions of the tunnel ventilation system, ensuring compliance with the strict requirements of the "Design Specification for Highway Tunnel Ventilation and Lighting".

Ultrasonic wind direction and speed sensors have the characteristics of compact structure, no moving parts, and durability. It can adapt to various environments, work normally 24/7, and provide reliable data for meteorological monitoring in various fields.
