Description
It measures the magnitude of acceleration, its changes, and the resulting velocity at a specific point on a structure to analyze structural stability and dynamic effects.
For long-term stable data acquisition, the housing and signal cable are fully watertight and moisture-proof, enabling use in harsh civil engineering environments while protecting against external impacts.
▣ Applications
① Measuring dynamic behavior of bridge cables
② Analyzing modal shapes, natural frequencies, and vibration acceleration
Composition & Characteristics
▣ Components
① Acceleration sensor & housing
② Signal cable
③ Mounting jig for sensor fixation
▣ Features
① High stability in extreme environments
② Excellent reproducibility and responsiveness, unaffected by cable length or resistance changes
③ Optimized design with high sensitivity for specialized applications
