Tunnel anemometer

Tunnel anemometer is used for highway tunnel environment detection，It adopts ultrasonic detection principle and can accurately measure wind speed and direction in the tunnel.Tunnel anemometer is a tunnel application type.The detection probe is installed on the tunnel wall to provide the tunnel main control room with detection values of wind speed and wind direction in the tunnel as the basic basis for ventilation and operation.The Tunnel anemometer 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 anemometer 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 anemometer 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.
