Brief Introduction
HY-WDS21E 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.
