Dynamic Displacement Sensor

The Dynamic Displacement Sensor measures structural movements when a displacement threshold is exceeded. It then captures a time window around the trigger and wirelessly transmits the data via LoRaWAN — ensuring efficient, event-based monitoring of dynamic structural behavior.

Durable hardware

Built for reliable use in harsh environments.

Dynamic motion. Measured directly.

Monitors structural displacement under dynamic conditions with millimetric precision—ideal for bridges, decks, and structural joints.

Dynamic displacement measurement

Measures relative motion along a single axis. Ideal for detecting structural motion caused by traffic, wind, or construction activity.

Event-based acquisition

Automatically triggers data capture when vibration exceeds a configured threshold. Each event includes 32 seconds of data: 12 seconds before and 20 after the trigger point.

Frequency analysis

Performs frequency extraction in the 0.7–15 Hz range, allowing modal identification and correlation with vibrational phenomena.

Rugged and weatherproof design

Aluminum IP67-rated enclosure ensures long-term durability in harsh environmental conditions, suitable for permanent outdoor installations.

What this sensor measures

Dynamic displacement

Measures displacement of the structure in mm with high precision.

Frequency

Identifies the main frequency component of each recorded event, supporting structural modal analysis and trend tracking.

Temperature

Onboard temperature sensor records data during each acquisition to support data correction and correlation.

Frequently asked questions

The DDS (Dynamic Displacement Sensor) sensor measures uniaxial dynamic displacements using a high-sensitivity MEMS accelerometer with double integration processing. It captures vibration-induced displacement in a single axis, with two selectable full-scale ranges: ±1.5 mm and ±3.0 mm. The sensor also records temperature for environmental compensation. It is specifically designed for structural health monitoring applications where detecting small, dynamic movements is critical.

The sensor operates on a threshold-based trigger system. When the detected displacement exceeds a user-configurable threshold, the device records a complete event consisting of 1600 samples at 50 Hz, corresponding to a 32-second window. Each recorded event includes the full displacement waveform, peak displacement value, dominant frequency, and temperature at the time of acquisition. Events are stored locally and transmitted wirelessly via LoRaWAN.

The sensor supports two selectable ranges: ±1.5 mm and ±3.0 mm. Corresponding resolutions are 0.012 mm and 0.024 mm, respectively. These can be configured through MyMove to match the precision and amplitude requirements of each specific use case.

Mounting orientation must match the sensor version. The vertical model must be installed with the “UP” arrow facing upward, while the horizontal model must respect specific lateral orientations to maintain measurement accuracy. It can be mounted to floors, walls, or ceilings using the supplied fixing plate and hardware.

With a typical configuration of 5 events per hour, battery life is estimated at around 2 years. However, frequent triggering, high structural vibration, or poor radio signal quality can significantly reduce autonomy. Optimal battery duration is achieved by calibrating the activation threshold appropriately and ensuring good line-of-sight connectivity to the nearest gateway.
