Epson Motion Sensor Modules - precision monitoring and measurement for critical infrastructure, navigation and stabilisation applications

Seiko Epson Corp. offers a comprehensive range of motion sensor devices capable of delivering high performance in compact packages. Their Inertial Measurement Units offer low power consumption, in the world's smallest size for this category. They also offer highly sensitive Accelerometers which support high dynamic range, low drift and digital output. We had the pleasure of catching up with the Epson team in Munich in November and getting our hands on the modules for ourselves.

Harnessing Precision: The Epson MA352-AD10 Accelerometer in Action

Introduction: Bridging the Micro and the Macro

In the realm of structural health and seismic monitoring, precision is key. The Epson MA352AD10 accelerometer stands as a testament to this principle. Our recent demonstration, featuring a model train setup, serves not just as a visual treat but as a profound insight into the intricate world of vibration monitoring and analysis.

The video illustrates a scaled-down yet powerful representation of how minor movement can be indicative of larger structural behaviours. The model train, moving back and forth on its track, simulates the kind of vibrations and movements structures might experience during seismic activities.

Understanding the Epson MA352-AD10 Accelerometer


  • High Sensitivity: This accelerometer detects even the slightest movement, essential for early seismic detection and accurate structural monitoring

  • Wide Frequency Range: It covers a broad spectrum of vibrations, ensuring no critical data is missed

  • Real-Time Data Analysis: The near-instantaneous data processing capability is crucial for timely decision-making in critical situations

  • Superior Noise to Signal ratio: Achieves low noise and high stability performance

  • High Stability: Achieves high stability and high resolution by resonance frequency change detection


Construction and civil engineering customers

  • Vibration-based structural health monitoring (e.g., monitoring the vibration characteristics of structures and judging their health & integrity)

  • Measurement of low-frequency environmental vibration, etc.

Large machines and large structures

  • Monitoring the safety of large structures (e.g., pipelines and large plants)

Seismic sensing

  • Measurement of vibrations accompanying earthquakes

What Does the MA352-AD10 accelerometer tell us?

Epson's model train setup is more than a demonstration; it's a micro-analysis of structural behaviour. The accelerometer's data, as seen in the video, showcases:

  • Displacement and Vibration Patterns: Understanding these patterns is vital in predicting the behaviour of larger structures under stress.

  • Reaction to Variable Forces: Just as the train's speed and direction vary, so do seismic forces, and the accelerometer's response to these changes demonstrates its adaptability.

Real-World Implications: From the Lab to the Field

This demonstration is a leap from theoretical to practical application. In real-world scenarios, the Epson MA352-AD10’s capabilities translate into:

  • Enhanced Safety Protocols: In earthquake-prone areas, its use can lead to better-prepared structures, reducing the risk of collapse.

  • Predictive Maintenance: For engineering teams, this means proactive rather than reactive maintenance, saving time and resources.
