  • Publication number: 20250130098
    Abstract: In the case of the conventional servo-type acceleration sensor, the sensor needs to be configured within a narrow range that simultaneously satisfies the following three conflicting challenges: (1) reduction in resonance peak, (2) improvement of responsiveness, and (3) improvement of sensor sensitivity. Therefore, there is a limit to performance improvement. A mechanical damping effect of a dynamic fluid pressure in the inter-electrode void portion is reduced by forming a flow hole, a flow groove, and the like at the relative movement surface of the electrode, and this damping effect is replaced with an equivalent damping unit by using an electrical circuit in the servo amplifier. As a result, although the sensor sensitivity, determined by the gap between the electrodes and the outer diameter of the electrode, and the sensor dynamic characteristics have conventionally been in a trade-off relationship, the sensor sensitivity and the sensor dynamic characteristics can be independently set.
