Abstract
PURPOSE: To calibrate the distance with the surface of measured body, by providing the measured section with definite size at the gap sensor measuring point of measured material and obtaining the change in the sensitivity of the gap sensor with the change in the gap sensor voltage produced at measured section.
CONSTITUTION: The gap sensor pick up 3 is provided at the external surface of the rotary shaft 2, the gap sensor pick 3 is fixed on the casing 6, and notch as measured section is provided at a part on the measuring circle of the rotary shaft 1 opposing to the gap sensor pick 3. When the rotary shaft 1 turns toward the arrow A, the output signal of the gap sensor 3 is as shown in Figure. That is, since the maximum value Vmax of the voltage change is the maximum depth (100μm) of the notch 7, even if the sensitivity of the gap sensor is changed, the voltage at the notch 7 can tell the relation between the change in the length and th voltage. Thus, always accurate phenomenon can be grasped.
