  • Patent number: 10209095
    Abstract: The present invention provides an eddy current sensor, comprising: a housing; a plurality of probes which are all disposed inside the housing, probing ends of the probes being all disposed at inner side of an exterior surface of the housing to avoid the probing ends of the probes from protruding out of the exterior surface of the housing. Because the probing ends of the plurality of probes are all located at the inner side of the exterior surface of the housing, the housing will protect the probes when the eddy current sensor is hit by an external force, thereby avoiding damage of the probes due to the impact, which reduces fault rate of the probes, enhances use reliability of the eddy current sensor, and prolongs service life of the eddy current sensor.

  • Publication number: 20170370958
    Abstract: 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.
