Tunnel wind speed and direction detector: capable of detecting even fainter changes in wind speed, meeting the strict requirements of tunnel ventilation management. [Model recommendation: TH-SQX1, IoT integrated device, customized service supported by Yunjing Tianhe] As the "sensing nerve" of the tunnel ventilation system, the tunnel wind speed and direction detector can capture subtle changes in wind speed as low as 0.01m/s through the combination of high-precision sensors and intelligent algorithms, and accurately analyze wind direction, providing real-time and reliable data support for tunnel ventilation management. Ultrasonic frequencies (usually 20kHz-100kHz) should be kept away from environmental noise bands to avoid interference from dust, rain, fog, and other sources. When the external wind speed is less than 0.5m/s, it is still necessary to monitor the air flow inside the tunnel to prevent the accumulation of pollutants. Under low wind speed conditions (such as 2-5m/s), accurately adjust the fan frequency to avoid energy waste caused by excessive ventilation. Support 10Hz-100Hz high-frequency sampling (i.e. updating data every 0.01-0.1 seconds), quickly capturing the piston wind effect when vehicles pass by (wind speed transients can reach 10m/s/s). The total delay from signal acquisition to data output is less than 0.5 seconds, meeting the real-time requirements of emergency scenarios such as fire and smoke exhaust.

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".
