Dynamic Displacement Sensor
The Dynamic Displacement Sensor measures high-resolution structural movements and activates only when a displacement threshold is exceeded. It then captures a time window around the event and wirelessly transmits the data via LoRaWAN — ensuring efficient, event-based monitoring of dynamic structural behavior.
Everything you need, built In
All Move Solutions sensors share the same foundation: precision, reliability, and seamless integration.

IP66/IP67-rated 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.

High-resolution dynamic displacement measurement
Measures relative motion along a single axis with high accuracy. 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.

Built-in frequency analysis
Performs real-time 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.

The DDS (Dynamic Displacement Sensor) sensor measures uniaxial dynamic displacements, capturing oscillations relative to the structure’s resting position. It is available in two distinct models: vertical (DECK002-V), which measures displacements aligned with the gravitational axis, and horizontal (DECK002-H), which captures motion along the ground plane. Both versions are optimized to detect structural responses to dynamic events such as vehicular loading, wind, or seismic activity.
The sensor operates on a threshold-based trigger system. When structural displacement exceeds the configured threshold, an event is recorded. Each event includes 32 seconds of high-resolution data sampled at 50 Hz: 12 seconds before and 20 seconds after the trigger. Displacement values and temperature readings are both stored and transmitted to the cloud 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.
