  • Patent number: 11187514
    Abstract: The capacitance-grating type digital display measuring tape includes a shell, a tape box, a tape body and a capacitance-grating sensor. A rotatable central shaft is disposed in the shell in an axial direction thereof. The tape box is mounted at one side in the shell close to the back side in the shell by the central shaft. A mainspring configured to pre-tighten the tape box is disposed in the tape box. The tape body is wound and collected in a groove in the outer circumference of the tape box. The capacitance-grating sensor is located in a position close to the front side in the shell. A self-adjusting mechanism is disposed at a position, corresponding to the outlet, on the inner wall of the shell. The self-adjusting mechanism automatically adjusts the speed at which the tape body extends out of or retracts into the shell.

  • Publication number: 20120105082
    Abstract: An absolute position measuring device suitable for wide-angle range measurement and providing the advantages of high precision, high resolution, and easy data processing. The measuring device includes a disk capacitive sensor, a measurement signal processing unit, a data processing unit, and a display unit. The disk capacitive sensor includes a rough division sensor and a fine division sensor. The pitch point value of the fine division sensor is at least two times higher than two resolutions of the rough division sensor. The rough division sensor and the fine division sensor have the same zero position. The grids of the two rough division and fine division sensors are independent to each other, are free of electric coherence, and are fixed relatively to each other. The grid has an exclusive absolute displacement value within a single pitch measurement range.
