Tunnel wind speed and direction detector

Tunnel wind speed and direction detector is a tunnel application type. Tunnel wind speed and direction detector is a device used to measure the wind speed and direction inside the tunnel, and monitor and record the wind speed and direction data inside the tunnel.The detection probe is installed on the tunnel wall to provide the tunnel main control room with detection values of wind speed and direction in the tunnel as the basic basis for ventilation and operation. Tunnel wind speed and direction detector can observe the operating status and detection data of the instrument in real time on site. At the same time, the analog and switching signals output by the data output interface can be connected to the PLC in the nearby sub-control room, and then connected to the main control room through the data optical terminal and optical fiber.

Tunnel wind speed and direction detector main features:

1. Cast aluminum body with anodized surface to adapt to harsh environment in tunnels

2. The sampling area spans the traffic lane in the tunnel to more realistically reflect the gas flow rate in the tunnel.

3. Adopts ultrasonic detection principle and is not affected by ambient temperature

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

Tunnel wind speed and direction detector installation method:

According to the requirements of the joint design drawings, it is installed directly on the tunnel wall, in the direction of tunnel traffic, on the right side of the tunnel wall, at a height of 3 to 4 meters. The transmission signal cable uses 2 twisted pair shielded wires or RVVP4*0.3.
