HY-WTE Tunnel Ultrasonic Wind Sensor, High Precision Ultrasonic Anemometer Measuring Wind Speed and Direction for Highway, Railway and Subway Tunnel Ventilation System
Introduction
A built-in time delay, variable from 00-99 seconds can be set to prevent very short duration gusts from causing false alarms. Only when wind speed reach preset value limit and last time exceed time delay, will the corresponding relay be triggered.If additional connections are made, the alarm can cause a remote warning light to flash, sound a remote horn or siren, and automatically actuate the crane brakes to prevent the crane from rolling.
