What is the working principle of a bridge icing sensor?

time :2025-02-05 Article Source:automatic weather station author :Small meteorological station

Bridges are a major aid for urban transportation, but in winter, whenever the temperature reaches freezing point, the freezing of the bridge deck can pose significant safety hazards to pedestrians and vehicles. Previously, it was laborious to conduct manual inspections at designated locations, but now it is different. With the bridge icing sensor, there is an automatic method.


The WX-JB1 bridge icing sensor combines IoT sensing to measure and report the icing situation of the bridge. With algorithm support, once the real-time data of water accumulation and temperature triggers the preset threshold, an alarm message will be immediately generated and pushed to relevant departments for timely disposal.


The core technology of bridge icing sensors is microwave disturbance technology. Its working principle is to monitor the icing information in the sensitive area of the sensor based on the difference in feedback signals of different substances such as ice, water, and air from microwave disturbance signals. The icing thickness is calculated based on the strength of the signal and the distribution information of icing in the sensitive area of the sensor.


The bridge icing sensor is suitable for various specifications of cables, with small size, light weight, and easy installation. It can monitor the icing situation in real time and activate the deicing system in a timely manner, changing the usual workflow of requiring inspection teams to constantly inspect and discover bridge deck icing, saving manpower and material resources.
