QL-BridgeSentinel BSR-200 – Bridge Health Monitoring Radar for Real-Time Structural Safety Assessment

QL-SlopeGuard™ XR-300 is a high-precision, all-weather slope stability radar designed for real-time landslide and geohazard monitoring. Using advanced SAR and interferometry, it provides 360° coverage and sub-millimeter deformation detection with ultra-low power consumption. Ideal for long-term, unmanned monitoring of slopes, mines, dams, and critical infrastructure.

OVERVIEW

Description

Real-Time Bridge Deformation Radar for Continuous Structural Health Monitoring

The QL-BridgeSentinel™ BSR-200 is a one-dimensional deformation radar system based on high-resolution radar remote sensing imaging and phase interferometry. Using electromagnetic waves as the medium, it performs real-time, dynamic, non-contact measurements of very small deformation on targets such as bridges, high-rise buildings, towers, and tunnels.

The complete system consists of a deformation radar host, display/control terminal, support structure, and power supply module. The display/control terminal connects to the radar host via a wireless network, and each terminal can control a single radar unit to achieve precise one-dimensional deformation measurement of the selected target span or structural element.

Compact, low-power, and field-ready, QL-BridgeSentinel BSR-200 is ideal for bridge load tests, long-term structural health monitoring, and rapid safety assessments with minimal traffic disruption.
