Multi-channel logger for displacement transducers and dial gauges, used in bridge deflection, settlement, creep and load tests.
Overview
The multi-channel displacement data-acquisition system is a bench-top static/quasi-static logger for bridge deflection, structural deformation, foundation settlement, creep and loading tests. It simultaneously connects several dial gauges, micrometers, resistive displacement transducers, LVDTs or magnetostrictive displacement sensors, converts their output to standard voltage/resistance, performs high-speed A/D sampling, digital filtering, linearisation and temperature compensation. A front-panel LCD shows each channel's displacement in real time; peak-hold, zeroing, channel scanning and on-board storage are supported, and USB/Ethernet links to a PC for long-term unattended logging and curve analysis. Channel count is expandable, resolution is at the micrometre level; widely used in bridge inspection, structural testing, settlement monitoring, universal-testing machines and R&D.
Applications
• Road and highway engineering laboratory testing
• Construction material quality control and acceptance
• Research and teaching laboratories
• Third-party inspection and certification bodies
Features
• Large LCD display showing real-time test parameters and results
• USB / RS232 data export to PC for further analysis
• 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 Multi-Channel Displacement Data Acquisition System comply with?
A1: The Multi-Channel Displacement Data Acquisition System 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 Multi-Channel Displacement Data Acquisition System 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.
