Device for measuring displacement. |
摘要 |
<p>A device for measuring displacement comprises a pair of sensor elements (4, 4) of which output voltage changes stepwise in dependence upon displacement of a measurement object, a differentiating circuit (6) for detecting time points at which the output voltage of the pair of sensor elements suddenly changes, and a counter (8) for counting the sudden change time points of the output voltage detected by the differentiating circuit.</p> |
