초록

A rotary apparatus comprises a shaft having a rotational axis, a rotation indicator formed on the shaft, a target feature proximate the rotation indicator, and a sensor proximate the target feature. The target feature extends circumferentially about the shaft, with a radial face transverse to the rotational axis and a circumferential face along the rotational axis. The sensor is oriented toward the rotation indicator to sense a rotational speed of the shaft, and oriented toward the target feature to sense transverse vibrations based on a radial distance ...
