High-Precision One-Dimensional Deformation Measurement Radar from China Suppliers and Factory for Bridge Health Monitoring
i
Product Introduction
One-dimensional deformation radar is a product based on high-resolution radar remote sensing imaging and phase interferometry measurement technology, using electromagnetic waves as the medium to conduct real-time, dynamic, and non-contact measurements of small deformation variables in targets such as bridges, high-rise buildings, towers, and tunnels.
The radar system consists of a deformation radar host, a display control terminal, a support component, and a power supply component. The display control terminal connects to the deformation radar host via a wireless network, and one display control terminal controls one deformation radar host to achieve one-dimensional deformation measurement of the target.

Frequently Asked Questions
-
QWhat types of structures can the one-dimensional deformation radar monitor?The radar is designed for a wide range of structural targets including bridges, high-rise buildings, towers, and tunnels. It supports simultaneous measurement of multiple points, making it highly versatile for civil infrastructure health monitoring projects.
-
QHow accurate is the deformation measurement?The system delivers a deformation measurement accuracy of ≤0.1mm with a data update rate of ≥200Hz, providing extremely high sensitivity suitable for detecting subtle structural changes in real time.
-
QDoes the device require physical contact with or installation on the monitored structure?No. The radar uses electromagnetic waves for fully non-contact measurement. In most cases, no reflectors or targets need to be installed on the measured structure, greatly simplifying deployment and reducing setup time and overall cost.
-
QCan the radar operate in adverse weather conditions or at night?Yes. The device is not affected by rain, snow, fog, or changes in lighting conditions and supports 24/7 continuous operation. Its IP66 protection rating makes it well suited for long-term outdoor and field monitoring applications.
-
QWhat is the maximum effective monitoring range of the device?The maximum measurement distance is ≥500m. A key advantage is that the accuracy of both deflection and frequency measurements remains consistent and is largely independent of the distance to the target structure.
-
QHow is measurement data processed and transmitted?The system adopts an edge computing architecture, so all data calculations are completed within the device itself without relying on external servers. It supports automatic remote data transmission, and the control terminal displays real-time displacement data while automatically saving data files for subsequent analysis.
