Description Overview GAOTek 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. Features Cast aluminum body, anodized surface for harsh environments Diverse sampling area can truly reflect the air flow rate in tunnel Ultrasonic measurement free from influence of ambient temperature Non-contact detection, no moving parts, low failure rate Technical Specifications Principle Ultrasonic technology Installation Wall of tunnel on one-side Range Wind speed – 30 m/s to 30 m/s Accuracy Wind speed ± 0.1 m/s Average Time 0.1 s to 60 min adjustable Relay Output 2 ways dry-contact relay output Digital Interface RS 232, RS 485 Analog Output 4 mA to 20 mA output (load < 500 Ω) Power Supply 220 V AC ± 10 %,50 Hz (or) 60 Hz Protection Grade IP 66
