Ultrasonic wind speed and direction detector in tunnel

The tunnel ultrasonic wind speed and direction detector adopts the principle of ultrasonic time difference method to obtain the wind speed and wind direction value in the tunnel.> The tunnel ultrasonic wind speed and direction detector has a cast aluminum body with anodized surface treatment, which is suitable for the harsh environment in the tunnel and has stronger stability. The FT-SQX1> tunnel ultrasonic wind speed and direction detector is a tunnel application type. The detection probe is installed on the tunnel wall to provide the tunnel master control room with the detection value of wind speed and wind direction in the tunnel as the basic basis for ventilation and operation. The detector can observe the operating status and detection data of the instrument in real time on site. At the same time, the analog and switch signals output by the data output interface can be connected to the ground PLC in the nearby sub-control room, and then connected to the main control room through the data optical transceiver and optical fiber.

Main features of tunnel ultrasonic wind speed and direction detector:

1. Cast aluminum body, surface anodized treatment, adapt to the harsh environment in the tunnel

2. The sampling area spans the traffic lane in the tunnel, which more realistically reflects the gas flow rate in the tunnel

3. Using ultrasonic detection principle, not affected by ambient temperature

4. Non-contact detection, no moving parts inside, reducing failure rate

Tunnel ultrasonic wind speed and direction detector installation method:

According to the requirements of the joint design drawings, it is directly installed on the tunnel wall, in the direction of tunnel driving, on the right side of the tunnel wall, at a height of 3 to 4 meters. The transmission signal cable uses two twisted-pair shielded wires or RVVP4*0.3.
