SODI Ultrasonic Wind Detector is specifically for the research and design of tunnel environment that provides a high performance of detecting solutions, detection sensor would be installed on the tunnel wall, provide tunnel wind speed and direction to control rooms, so as to be a fundamental basis of ventilation and operations. The output analog of data output interface and switch signal can access points near the PLC control indoor, then access control rooms by data optical transceiver and fiber. It has excellent performance, the character of high precision, low maintenance and low operation cost.
