Nederlands ES-W3033 Ultrasonic Wind Speed sensor For Tunnel is a special type for tunnel. The detection probe is installed on the tunnel wall to provide the wind speed and wind direction detection value in the tunnel for the tunnel general control room as the basic basis for ventilation and operation. At the same time, the analog and switch signal output from the data output interface can be connected to the PLC in the nearby sub control room, and then the data optical transceiver and optical fiber can be connected to the main control room.
