Title:
EDDY CURRENT SENSOR FOR ROTARY SHAFT, AND ROTARY SHAFT APPARATUS
Document Type and Number:
WIPO Patent Application WO/2016/127627
Kind Code:
A1
Abstract:
An eddy current sensor for a rotary shaft (100), and a rotary shaft apparatus. The eddy current sensor comprises: a housing (10); one or more position detection probes (20, 30) provided on the housing (10); and a rotating speed detection probe (50) provided on the housing (10). The eddy current sensor integrates position detection probes (20, 30) and a rotating speed detection probe (50). That is, while the eddy current sensor is used for detecting position displacement of a rotary shaft (100), a rotating speed of the rotary shaft (100) can be simultaneously detected, thereby aiding in more comprehensive detection and monitoring of the rotary shaft (100). Moreover, detected position data and rotating speed data of the rotary shaft (100) correspond to each other in real time, and therefore, a working state of the rotary shaft (100) can be more carefully analysed using the corresponding data.
