Ferraris Acceleration Sensor - Principle and Field of Application in
نویسنده
چکیده
The Ferraris principle for measurement of the relative acceleration has been known for more than 100 years. In academic works the potential of this sensor principle has been demonstrated again and again /1, 2/. But only commercial production which has been started some years ago opened up possibilities for the sensor principle in industrial applications. The simple and robust design, combined with non-contact object measurement, predetermines the sensor for application in rotary and linear motion axis. Ferraris sensors can be used either for analysis of motion behaviour or for improved control of servo drives of all kind. This lecture describes the principle, the design and the profitable application fields of the relative acceleration sensor.

Scale-Dependent Dynamic Behavior of Nanowire-Based Sensor in Accelerating Field
The accelerating fields (e. g. centrifugal acceleration and constant acceleration) can change the physical performance of nano-sensors significantly. Herein, a new size-dependent model is developed to investigate the scale-dependent dynamic behavior of nanowire-fabricated sensor operated in an accelerating field. The scale-dependent equation of motion is developed by employing a consolidation o...
