The Acceleration Sensor for Bridge is a high-performance three-axis capacitive accelerometer engineered specifically for structural health monitoring of bridges and other critical infrastructure. Designed to capture precise vibration and dynamic load data under real-world conditions, this sensor delivers reliable, continuous monitoring of bridge behavior — from traffic-induced oscillations to environmental excitations such as wind and seismic events. With a robust housing, wide frequency response, and excellent temperature stability, it serves as a foundational component in modern bridge safety and maintenance systems.
Three-Axis Vibration Monitoring: Simultaneously measures accelerations in X, Y, and Z directions for comprehensive structural dynamics analysis.
Wide Frequency Response (0–1000 Hz): Ideal for capturing both low-frequency deformations and high-frequency vibrations.
Superior Temperature Performance: Operates reliably across a wide temperature range (-20°C to +80°C), suitable for outdoor applications year-round.
High Shock Resistance: Withstands transient shocks up to 5000g, ensuring durability under extreme or accidental loads.
Low Noise & High Sensitivity: Delivers clean, accurate signals for detecting subtle structural changes and early-stage anomalies.
Easy Installation and Integration: Supports screw mounting or adhesive attachment, with standardized voltage output for seamless connection to data acquisition systems.
