Bridge structural safety monitoring is a core measure to ensure long‑term stable operation of transportation infrastructure. Under the influence of vehicle load, temperature change and geological settlement, bridges will produce tiny deformation and displacement. The KTC pull‑rod linear displacement sensor can capture these micro‑changes in real time, providing reliable data support for bridge health assessment.
The KTC linear displacement sensor adopts a rigid pull‑rod structure with an aluminum alloy shell, featuring compact size and easy field installation. It delivers high‑precision continuous position feedback with excellent linearity and repeatability. The internal conductive plastic measuring core ensures stable output signal, strong anti‑interference ability, and adapts to outdoor complex environments such as humidity and dust. With long service life and low maintenance cost, it can work stably for a long time in unattended monitoring sites.
In practical bridge monitoring projects, the sensor is fixed at key deformation positions of the bridge. It is installed on bridge expansion joints to detect the telescopic displacement caused by temperature fluctuation, judge whether the expansion device works normally. Mounted on bridge piers and support structures, it monitors settlement and offset displacement generated by foundation deformation. It is also applied in the strain monitoring of main girders, recording the micro‑displacement under dynamic vehicle loads, so as to analyze the stress state of bridge components.
Real‑time displacement data collected by KTC sensors is transmitted to the monitoring system. When the deformation value exceeds the safety threshold, the platform will trigger an early warning prompt. Engineers can evaluate the structural aging degree and potential risks of the bridge through long‑term data comparison, arrange maintenance plans in advance and avoid safety accidents.
As a cost‑effective displacement measuring device, the KTC linear displacement sensor realizes automatic and continuous bridge health monitoring. It reduces manual inspection workload and improves the intelligence level of bridge safety management, which is widely used in daily safety monitoring of highway bridges, viaducts and large‑span bridges.
