BBOX 2.0 · Monitoring

How continuous structural monitoring works

Structural Health Monitoring to follow how the structure evolves over time, seismic monitoring to record its response during the event. Two modes in the base configuration of the same system.

The two modes

SHM and seismic monitoring compared

Both modes run on the same sensors and answer different questions. Structural Health Monitoring follows the structure in ordinary service; seismic monitoring records its response during an event.

System expansion

Project-specific configurations

Through ESA expansion units, the BBOX 2.0 Datalogger integrates sensors other than accelerometers. It accepts any sensor with a 4-20 mA output, and others through a dedicated adapter: instrumentation already installed on a structure, common on bridges, joins the same system. A single Datalogger manages the whole set, keeping acquisition, transmission and data access centralised.

Strain gauges
Local deformations of beams, columns, and slabs.
Crack meters and displacement transducers
Crack opening and relative displacements between parts of the structure.
Advanced inclinometers
High-precision static inclination measurement.
IEPE accelerometers
For specific frequency bands or interfaces.
Temperature and humidity
Environmental correlation essential in SHM.

SHM and event-based monitoring in the base configuration. Project-specific configurations when the project requires them.

Both operating modes are available with no additional components, with remotely configurable parameters. Expansion with different sensor types is activated when the required information goes beyond accelerometry.

Monitoring applied to your type of structure

Requirements change with the structure: a production plant, a bridge and a historic church raise different questions. Each page describes the objectives, the measured quantities and the report contents for that context.

Which configuration suits your structure?

MOSI supports the definition of the most appropriate technical configuration, based on the structure, the monitoring objectives, and the operational context.
