In today's world, accurate crack measurement is essential for assessing the safety and integrity of buildings, bridges, and infrastructure. Small cracks can gradually grow due to load, temperature changes, ground movement, or material fatigue. Without continuous monitoring, these changes are often detected too late. Our IoT sensors for crack measurements provide real time insight into crack movement and structural strain, enabling early intervention and informed maintenance decisions.
Our IoT sensors continuously monitor the critical parameters required for reliable crack measurement and structural assessment.
Linear Position Way
Linear position sensors are installed across a crack with one mounting point on each side. They measure changes in distance over time, providing precise data on crack opening or closing in millimeters or centimeters. This allows gradual movement and sudden shifts to be detected accurately.
Vibrating Wire for Strain
Vibrating wire strain sensors measure internal strain within structural components near or around a crack. By monitoring changes in strain, these sensors provide insight into load distribution, stress development, and potential structural weakening beyond visible crack movement.
By combining linear displacement and strain measurements, crack monitoring systems provide a complete picture of how cracks develop and how structures respond to stress. This enables proactive maintenance, improved safety, and longer asset lifecycles.

Early Detection of Structural Changes
Real time monitoring reveals crack growth and strain development before damage becomes critical.
Improved Structural Safety
Continuous insight supports timely interventions and reduces the risk of sudden structural failure.
Reduced Manual Inspections
Automated monitoring minimizes the need for frequent visual inspections and site visits.
Objective and Traceable Data
Accurate measurements provide reliable data for engineers, reports, and compliance documentation.
Better Maintenance Planning
Trend analysis enables maintenance and repair decisions based on actual structural behavior.
Remote Monitoring Capability
Sensors deliver continuous insight in hard to access or high risk locations such as bridges, tunnels, and façades.
Structural cracks rarely fail without warning. Measure crack movement and strain in real time and act before small changes become major risks.
