DECKAXE-SHM

Accelerometer

Wireless triaxial sensor for acceleration monitoring The Accelerometer is a wireless, battery-powered sensor that measures structural vibrations on three axes with high resolution. Designed for dynamic monitoring and modal analysis, it records acceleration events with a programmable sampling rate from 40 to 640 Hz. It can acquire threshold-triggered events automatically when a threshold is exceeded, or can be set in programmed mode when high synchronization accuracy among different sensors is required. Ideal for many applications, it enables synchronized data acquisition with high time synchronization for advanced structural diagnostics and long-term monitoring strategies.

Everything you need, built In

All Move Solutions sensors share the same foundation: precision, reliability, and seamless integration.

Wireless connectivity

Long-range, low-power data transmission ideal for remote and large-scale sites.

Long-term battery autonomy

Multi-year operation with adjustable sampling and transmission settings.

Full remote configuration

Configure settings, calibrate sensors, and manage alarm thresholds, all in one platform.

Durable hardware

IP66/IP67-rated for reliable use in harsh environments.

Main features

High-speed data. Structural dynamics in motion.

Captures high-resolution triaxial acceleration for modal analysis and vibration studies, supporting synchronized campaigns across assets.

Triaxial vibration measurement

Captures structural acceleration on three axes with high resolution, enabling comprehensive detection of even minor vibrational modes.

Dual acquisition modes: programmed and threshold-triggered

Programmed (time-triggered) mode – synchronized (with high accuracy) acquisition at fixed intervals: 1, 2, 6, 12, 24 h Threshold-triggered mode – event-based acquisition when a predefined acceleration threshold is exceeded

Compatible with MyMove Modal Analysis Tool

Thanks to sub-millisecond synchronization (±500 μs), multiple accelerometers can be configured for modal analysis via MyMove's Modal Analysis Tool. This enables computation of: • Modal frequencies • Mode shapes • Damping ratios Perfect for dynamic characterization of bridges, towers, and large-scale structures, the tool provides time-aligned data visualization, automatic frequency identification, and cross-sensor correlation

Perfect for synchronized modal analysis

Multiple accelerometers can be precisely synchronized to analyze structural dynamics and perform frequency-domain assessments across complex structures.

What this sensor measures

Triaxial acceleration

Records X, Y, and Z axis acceleration during vibration events, measured in mg. Enables modal identification and peak detection.

Dominant frequency

Calculates the dominant frequency component of each vibration event within the selected bandwidth, useful for dynamic system characterization.

Temperature

Included in each event to correlate structural behavior with ambient conditions.
