Abstract
A monitoring device for a rotary machine is a monitoring device for monitoring a clearance of a rotary machine including a casing for housing a rotating part and a stationary part, including: at least one position sensor disposed outside the casing and configured to detect a relative position of the casing to the rotating part in a radial direction; and an estimation unit configured to obtain an estimated value of an internal clearance between the rotating part and the stationary part in the casing, based on a measured value detected by the at least one position sensor.
