Bridge deflection detector for measuring deflection of bridge spans during load tests and structural health assessment. Contact iRoad for details.
Overview
The bridge deflection detector measures the vertical deflection of bridge spans under static and dynamic loads. It is used in bridge load tests, acceptance testing and long-term structural health assessment of highway and railway bridges. Measurement points are set at key positions along the span, and the system records deflection in real time and outputs deflection curves and test reports for evaluating bridge stiffness and load-carrying capacity.
Applications
• Bridge load testing and acceptance inspection
• Long-term structural health monitoring of highway and railway bridges
• Bridge safety assessment after natural disasters or overloading
• Research and educational laboratories
Features
• Robust construction suitable for both laboratory and field use
• Compliant with relevant Chinese and international testing standards
• Complete with calibration certificate and operation manual

FAQ
Q1: What standards does the Bridge Deflection Detector comply with?
A1: The Bridge Deflection Detector is designed and manufactured in accordance with relevant Chinese national (GB) and transport industry (JTG) standards, as well as applicable ASTM and AASHTO international standards. A calibration certificate traceable to national standards is provided with each unit.
Q2: How often should the Bridge Deflection Detector be calibrated?
A2: We recommend annual calibration by authorized technicians or by iRoad after-sales service center. For high-frequency laboratory use, semi-annual calibration is advised. The instrument is supplied with a factory calibration certificate.
Q3: What is the lead time and do you provide training?
A3: Standard units are usually shipped within 7-15 working days. Custom configurations may require 20-30 days. iRoad provides on-site installation, commissioning and operator training for major equipment; remote video guidance is available for standard laboratory instruments.
