Tunnel anemometer: compact in size, compact in structure, and flexible in installation, it can adapt to different tunnel environments. [Model recommendation: TH-SQX1, IoT integrated device, cloud environment Tianhe supports customized services] As a key equipment for tunnel environment monitoring, tunnel anemometer can efficiently adapt to different tunnel environments (such as narrow spaces, complex sections, high humidity/high dust, etc.) with its core advantages of compact size, compact structure, and flexible installation, providing reliable data support for ventilation control and safety warning. By adopting ultrasonic transducer miniaturization technology (such as probes with a diameter ≤ 5cm), the overall volume of the instrument is reduced by more than 60% compared to traditional mechanical anemometers, and the weight is reduced to less than 1kg, making it easy to install handheld or deploy with the assistance of drones. Integrated high-precision temperature sensor, supporting wide temperature operation from -40 ℃ to+70 ℃, suitable for tunnels in cold regions (such as Northeast China) and high-temperature tunnels (such as smoke exhaust ducts in Southern China). Using a metal shell or conductive coating to shield strong electromagnetic fields (such as high-voltage cables and variable frequency fans) from interference inside the tunnel, ensuring data transmission stability. A certain highway tunnel reduced ventilation energy consumption by 15% and increased CO concentration compliance rate to 99% through flexible deployment of detectors.

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.

Product Features:
