First Sensor is launching a new generation ofhigh-accuracy capacitive silicon inertial sensorsaimed at applications in the fast-growing market of smart structural monitoring. The new sensors offer the resolution and low noise density required for recording vibrations or changes of inclination in wind turbines, bridges, and high-rise buildings, thereby uncovering risks in the structure or material at an early stage.
Integrated in smart solutions, these highly cost-effective sensors ensure the safety of structures both in everyday operation and following events such as storms, earthquakes, large loads or changes in the foundations. The sensors for measuring tilt, acceleration and vibration consist of a silicon sensor element made in accordance with a patented micromechanical process (HARMS, AIM) in conjunction with a signal-processing ASIC in a hermetically sealed SMD housing.
Ensuring the safety of exposed structures such as bridges and wind turbines still usually involves time-consuming visits and inspections. Remote structural monitoring using smart sensors creates an attractive growth market because these technologies can be used to continuously monitor and analyze the condition and loading of buildings, bridges and wind turbines. Repairs and safety measures can be organized much more effectively, while potential risks following extraordinary events such as earthquakes, storms and landslides can be better assessed.
To perform these tasks, the inertial sensors from First Sensor achieve resolutions of 10 µg or 0.0005° (2 arc seconds) depending on the bandwidth. In addition to standard models, First Sensor also develops modules that are mechanically and electrically adapted for special customer applications. To support projects and developers, evaluation kits are available for the quick and easy evaluation and configuration of the sensors.
