An eddy current sensor for a rotary shaft and a rotary shaft apparatus. The eddy current sensor includes: a housing; one or more position detecting probes provided on the housing; and a rotating speed detecting probe provided on the housing. The eddy current sensor integrates the position detecting probe and the rotary speed detecting probe, such that while the eddy current sensor is detecting position displacement of the rotary shaft, the eddy current sensor may also simultaneously detect the rotating speed of the rotary shaft, which facilitates detecting and monitoring the rotary shaft more comprehensively. The detected position data and rotating speed data of the rotary shaft correspond to each other at any time, such that the working state of the rotary shaft may be analyzed more intensively.
