Tunnel Ultrasonic wind sensor (SMKB-Wsonic1)
SMKB-Wsonic1 ultrasonic wind speed and direction sensor is specially designed for the tunnel application, it’s installed on the tunnel wall and providing real-time tunnel wind data to total control room, as a basic basis for ventilation and operation. At the same time, the analog and digital signals output from sensor can be connected to the PLC in the nearby sub-control room and then to the general control room through optical fiber
Main Features
- Cast aluminum body, anodized surface for harsh environments in the tunnel
- Ultrasonic measurement free from influence of ambient Temperature
- Non-contact detection, no moving parts, reduce the failure rate
