Detecting Small Changes in Inclination and Acceleration with Inertial Sensors
First Sensor features an extremely innovative technology system for manufacturing high-precision inertial sensors for condition monitoring, geo-engineering or navigation applications. The MEMS sensors allow for versatile customization to fit the specific application requirements of the user.
Inclinometers and Accelerometers
The capacitive inclinometers and accelerometers are based on single crystal silicon sensor elements and use advanced micromachining technology to realize large signal-to-noise ratios and superior stability over temperature. Thus, they are able to detect very small changes in acceleration or inclination. Because of high aspect ratio microstructures (HARMS), the sensors feature ultra-low cross axis sensitivities. Additionally, the patented highly flexible Air gap Insulated Microstructures (AIM) technology reduces parasitic capacitances.
All inertial sensors can be tailored, and can be adapted or developed to fit specific needs or applications.
