FTQN-J Wireless Data Transmission Bridge Deflection Detection System

I. Overview

It can perform real-time time-domain analysis of the deflection at the mid-span and designated points of railway bridges when trains pass through. The deflection waveform is recorded via USB drive, and the analysis software can conduct time-domain analysis on the waveform, with graphical and report display and printing capabilities.

II. Principle Introduction

Utilizes the FTWY series displacement sensors to measure the real-time vibration of the bridge. The sensors transmit data to the host unit via wireless transmission modules, which then relay the data to a computer through a USB port. The sensors are powered by lithium batteries, eliminating the need for extensive wiring during on-site measurements, making them convenient to use.
