CYLINDER POSITION MEASURING DEVICE AND CYLINDER POSITION MEASURING METHOD |
摘要 |
<p>An arithmetic processing portion is configured to perform a correction process for resetting an original position of the stroke position by using at least detection results of a voltage value of a first magnetic force sensor as well as a second magnetic force sensor according to the piston movement, and further not to perform the correction process to reset the original position of the stroke position by using the detection result of the first magnetic force sensor and the second magnetic force sensor right after an abutment when the piston is abutted to the stroke end based on a detection result of a stroke end abutment detecting system.</p> |
