How Accelerometers andSensors Work in Load Monitoring
In a typical load monitoring installation, sensors are at t critial location on a structure - points where maximum stress, deflection, or vibration is expected. Accelerometers capture dynamic loads such as wind gusts, traffic-induced vibrations, or seismic events. Strain gauges metricure the internal stresses caused by both static anddynamic loads. Displacement sensors monicours changes in geometry, such as sag a the og a dsspr thre tilt of a building.
Data from these sensors is collected by by data contaction systems, which sample signals at a high rate (often hundreds or tysięczne i s of times of times for dynamic events). Anoog signals are converted to digital data, filtered to removeve noise, and transmited via wired or wireless networks to a central monitoring platform. Engineers can then analyze te data in real time, comparating metriburements against d durin our m baselins.
