Structural Health Monitoring


Structural Health Monitoring is a term increasingly used to describe the possible implementation of a range of automated monitoring systems able to assist operators and inform about the ‘fitness for purpose’ of structures under gradual or sudden changes to their state.

SHM is very cost intensive

Monitoring systems are becoming increasingly sophisticated and accurate. But also very expensive, which is the main market barrier.

Difficult and long engineering process

A significant challenge is that every structure is unique, which means custom projects = difficult and long engineering processes.

Only on very selected targets

Due to cost reasons, to date, most infrastructure and buildings are void of any form of Structural Health Monitoring.

Application fields with difficult solutions

Application of monitoring solutions to rods, pipelines and penstocks is extremely challenging, so is retrofit of existing structures.

The InStar System gives a valid response to the growing need for cost effective,easy to handle and
remote Stuctural Health Monitoring technology able to increase the resilience
and security of infrastructure and buildings, reduce maintenance costs
and simplify remaining live prediction.

INSTAR Sensor System


The InStar Sensor System offers a completely new approach to SHM: it’s a standard, low cost and stand-alone solution able to adapt to custom projects. At the heart of the system is an innovative, patented Smart Skin Deformation Sensor, based on the use of advanced composite material.

Four Values


Each Smart Skin Sensor measures four main values: strain, temperature, tilt and seismic activity, further values are easily integrable.

Strain

Next generation strain sensor. Static, perfectly resistant to external agents and requires no wiring.

Temperature

Temperature sensor included in the sensor system. Accuracy of +/- 0,1°C (-30/+75°C range)

Tilt

Integrated tilt measurement for data contextualization. Accuracy of 0,1° on three axes.

Seismic activity

Integrated seismometer, able to trigger higher acquisition frequency (oversampling).

Cloud Architecture


Pilot Installations


InSensus Project is running Pilot Installations on high profile targets such as an historic tyre plant in Nothern Italy, completely remodeled in 2012 and a hydro power plant in Aosta Valley. In2017 two more Pilot Installations will follow -one in an Alpine Base Tunnel, the other in an Alpine Road Tunnel.
