Tunnel anemometer

Tunnel anemometer is a professional tunnel environment monitoring equipment to monitor the wind speed and direction in the tunnel, which can be real-time monitoring all weather.Tunnel anemometer is a tunnel application type. The detection probe is installed on the tunnel wall to provide the tunnel control room with wind speed and wind direction detection values in the tunnel as the basic basis for ventilation and operation. Tunnel anemometer can observe the instrument operation status and detection data 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 underground 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, anodized surface, suitable for harsh environment in tunnels

2. The sampling area spans the lanes in the tunnel, which more truly reflects the gas flow rate in the tunnel

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

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

Tunnel anemometer installation method:

According to the requirements of the joint design drawings, it is directly installed 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 cables or RVVP4*0.3.
