    • The present invention relates generally to a new type of inductive displacement sensor, composed of a scale and a winding element. The scale is a conductor with two rows of parallel and uniform distribution of a grid. The scale and winding elements can be moved in the direction of the grid distribution. The winding element is spaced on opposing face of the scale; the winding elements include the first winding, the second winding, the third winding and the fourth winding. The first winding and the second winding cross wind to form the driving winding element, thereby forming the pattern, third winding fourth cross winding constitute two sensing winding elements, with the two sensing winding elements along the direction perpendicular to the grid distribution of each side of the element distribution in driving winding forming patterns. One end of the first winding is connected to one end of the second winding and form a common end which is connected with the electronic device. Both the sensing windings and the driving windings have a space along the grid distribution and aligned along the grid distribution. The present invention reduces the direct coupling between drive winding element and the sensing winding elements, reducing the potential for incompatability of assembling clearance error, and to a certain extent, reduces distortion measurements, enhancing the stability of the sensor and the accuracy of measurement.

    • The current marking gauges, mortise gauges and circle marking gauges on the market require use of a ruler to measure distances prior to marking, which is inconvenient and time consuming. Moreover, the accuracy of the marked dimension is inexact due to the low accuracy of using a ruler. Furthermore, parallax error created by transferring the measured distance between the rule and the gauges also needs to be accounted for, which reduces accuracy even further. This present invention helps to improve the accuracy of the measurement and marking of the gauges, increases efficiency, convenience, saves time and is easy to use. The new product is a digital multifunctional marking gauge, that includes a Digital Unit, Main Slider, Beam, Display, Fixed Pin, Adjustable Pin, Adjustment Slider, Fence, Calibration Frame, Calibration bar, Setting Block, Scriber, Set function button of the Digital Unit, Locking Screw, Fixing Screws and related components.
    • 目前市面上的标记量规,榫眼和圆圈标记仪要求使用尺子来测量标记之前的距离,这是不方便和耗时的。 此外,标尺尺寸的精度由于使用标尺的准确度低而不准确。 此外,还需要考虑通过传递规则和量规之间的测量距离而产生的视差误差,这进一步降低了精度。 本发明有助于提高量规的测量和标记的精度,提高效率,方便,节省时间,易于使用。 新产品是数字多功能标记仪,包括数字单元,主滑块,光束,显示器,固定针,可调节针,调整滑块,围栏,校准框,校准杆,设置块,划线器,设置功能按钮 数字单元,锁定螺丝,固定螺丝及相关部件。
