摘要： The present application provides an eddy current sensor for a rotary shaft and a rotary shaft apparatus. The eddy current sensor comprises: a housing; one or more position detecting probes provided on the housing; and a rotating speed detecting probe provided on the housing. By applying the technical solution of the present application, 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, it may also simultaneously detect the rotating speed of the rotary shaft, which facilitates detecting and monitoring the rotary shaft more comprehensively; besides, the detected position data and rotating speed data of the rotary shaft are corresponding to each other at any time, such that the working state of the rotary shaft may be analyzed more intensively.

摘要： A Ferraris sensor for measuring acceleration contains a scanning head (6) which consists of magnets (2) and detector coils (3) which are disposed alternately in a direction of acceleration (X). The scanning head (6) has a yoke structure surrounding an eddy-current body (1) and a compact structure. Magnetic fields (2a, 4a) and detector coils (3) are arranged in a perpendicular position with respect to the surface (1) of the eddy-current body (1), enabling good signal generation. It is particularly advantageous to arrange the magnets (2) and detector coils (3) on a ferromagnetic support structure (5) and to arrange a ferromagnetic counter structure (7) on the side of the eddy-current body (1) opposite the scanning head (6)
