Rotational motion fluid loop sensor using magnetically levitated detecting element |
摘要 |
A rotational motion sensor has a circular, tubular body (1) filled with a fluid. A sensor head (6) forming part of the body houses a movable detecting element in the form of a piston (7) which is magnetically levitated so that it is kept out of contact with the sensor body. Movement of the piston is detected in a number of different ways including using a variable magnetic reluctance pick-off (4, 5).
