Abstract
An electronic measuring device for measuring and displaying a linear displacement of a horizontal screw mechanism, the device comprising: a gravity acceleration sensor adapted for measuring an angle of rotation value of a horizontal rotational shaft of a screw mechanism; a data processing unit for converting the angle of rotation value into a linear displacement value according to characteristics of the linear screw mechanism; and a digital display unit for displaying the linear displacement value; in which the gravity acceleration sensor, the data processing unit, and the digital display unit are electronically or electrically connected.
